3. A. acidic
4. HCl is a weak acid; [tex]CH_3COOH[/tex] is a weak acid.
5. A. [tex]K_b=\frac{[OH^-][C_5H_5NH^+]}{[C_5H_5N]}[/tex]
Explanation:
1. pH is the negative logarithm of hydrogen ion concentration.
[tex]pH=-log[H^+][/tex]
Given: [tex][H^+]=5.0\times 10^{-2}=0.05[/tex]
[tex]pH=-log[0.05M]=1.30[/tex]
2. An acid is a substance which donates [tex]H^+[/tex] ions when dissolved in water.
A base is a substance which donates [tex]OH^-[/tex] ions when dissolved in water.
Thus as water ionizes to give both ions, it acts as both acid and base.
[tex]H_2O\rightarrow H^++OH^-[/tex] which is called as self ionization.
3. pH is the measure of acidity or alkalinity of a solution. \Acids have pH less than 7, neutral solutions have pH of 7 and basic solutions have pH more than 7.
As the given solution has a pH of 6.8 which is less than 7, it is an acidic solution.
4. Strong acids are those acids which undergo complete dissociation when dissolved in water.
[tex]HCl\rightarrow H^++Cl^-[/tex]
Weak acids are those acids which do not undergo complete dissociation when dissolved in water.
[tex]CH_3COOH\rightleftharpoons CH_3COO^-+H^+[/tex]
5. Dissociation constant is the ratio of product of concentration of products to the product of concentration of reactants each raised to their stochiometric coefficients.
[tex]C_5H_5N+H_2O\rightarrow C_5H_5NH^++OH^-[/tex]
[tex]K_b=\frac{[OH^-][C_5H_5NH^+]}{[C_5H_5N]}[/tex]
The concentration of water is ignored as it is in large excess and thus does not effect the dissociation of pyridine.
1. B. text messages.
Workplace communications tend to be conversational and informal in text messages because it is a type of communication that is done with colleagues mostly. There are types of communication in the workplace that are structured for specific purposes, so they are not conversational or informal.
2. D. Addressing a problem
A negative workplace writing is a type of writing that deals with the negative aspect of communication, as communicate traditionally “bad thing”, like a problem, should follow specific rules in order to address the issue in a way that could lead to the resolution of the problem in the first place.
3. B. Glossary
A glossary is a list of terms with the relative meaning, so it can help with the identification of the meaning of a scientific term. Typically, a glossary is more specific on the subject that the book is dealing with, while a dictionary contains all the words from every subject.
4. B. Quotations
Quotations typically stand out when scanning texts because usually they are formatted with italic or bold, and there is usually some space between the text from the author and the quote. These typographic elements help the quote to stand out from the rest of the text.
5. C. Telling a story
Narration is the art of telling a story. Other forms of writing typically have other purposes, while the specifical aim of a narration is to tell a story. Typically, in a narration, there is also an emotional component that in other forms of writing are not present.
6. D. Why?
The Five Ws and One H is a strategy used to tell a fact or a story with the aim of conveying all the important information. The Why? question helps to understand the reasons behind a historical fact, addressing the cause behind it and the various reasonings.
7. D. words and phrases to use.
Knowing your message and your audience is important because if you know that aspect, you could choose the words and phrases to use, as both audience and message are key aspects when you have to write something. For example, if you have to write an article for a scientific journal, your words and phrases will be different than if you have to tell a story to a group of kid.
8. B. First person
Using the first person helps to tell a story from the main character perspective, as the reader sees the narrator as the character. The first person is used with the pronoums “I”, “me” and “we” and it’s a subjective point, so the narrator doesn’t know everything, but only what he/she experience.
9. D. Tone
The tone of an email or every written text can help us determine what was the emotional state of the writer, as the way the phrases are formed and all the textual elements will form a pattern that is recognizable for the readers. So, from the tone of an email, it is possible to determine whenever the writer was pleased or angry.
10. D. Bias
A bias is something that is presented as a fact, but in reality, it hides some form of inclination or prejudices, or even a mistake or an error about the specific topic that the bias is about. Usually, a bias it is used to convince other about something, in order to maintain the prejudice behind that information.

These are the questions I can answer but for the rest I recommend to do some research on.
Solution A is a Weak Alkali, Solution B is a strong Acid.
Explanation:
At pH 10, the colour is blue, therefore it's a weak alkali.
At pH 1, the colour is red, therefore it's a strong Acid.
no solution
Step-by-step explanation:What is the solution to the system of equations?
5x – 4y = 6
–5x + 4y = –10
(4, 4)
(–2, –5)
infinitely many solutions

Part 1.
The correct option is the option C which is all cells come from the pre-existing cells.
Explanation:
Mitosis is the cell division in which one cell divides into two identical cells having same number of chromosomes.
So a cell divide into two giving two cells which further divides.
Even a whole organism come from the division of single cell which is made from the combination of an egg and sperm.
Part 2.
The correct option is the option A which is gene.
Explanation:
DNA contains all the information necessary for a whole organism.
A gene is the unit of DNA which describes a single trait.
For example gene of eye color and gene for insulin production.
So the gene is exact answer to this question while proteins and phenotype are less relevant to question.
Part 3.
Graphs are not given in this question but a graph Will be hyperbola type of inversely proportional. The line in graph descends.
Explanation:
If distance square is on x axis and intensity of light on y axis, The line will move from upward to lower direction.
In the graph at initial distance means low square of distance the intensity will be high and as the square distance increases the intensity will become low.
The line on the graph will descends as the distance square on x axis increases.
Part 4.
The correct answer will be option B.
Explanation:
The process of generating sugar from the carbon dioxide and water in the presence of light and green pigment chlorophyll is known as the photosynthesis.It occurs mostly in leaves off plants.While respiration is the breakdown of food generating energy.And digestion is simplification of complex molecules and osmosis is the transport of water across membrane.Hence photosynthesis is the correct answer.
Part 5.
The correct answer is the option D which is the population of frogs and mice would increase which would cause the population of grasshoppers to decrease.
Explanation:
Snake is the tertiary consumer in a food web and frogs and mice are secondary consumer while grasshopper is the primary consumer.
As the snake is removed from the food web the population of frogs and mice will increase due to the less pray of secondary consumers.
As frog and mice will increased they will eat more grasshopper making decrease in grasshopper population.
Part 6.
The correct answer is the option B which is the volume of block B is more than A.
Explanation:
The rate of sinking depends upon the density of blocks.
As we know both blocks sink at the same rate. Hence both blocks have same density.
Now the mass measured of block B is more than block A.
But their mass to volume ratio is same. So it means block B has more mass with more volume making density equal to block A.
Part 7.
The correct answer is the option B which is the solution is the base.
Explanation:
Litmus papers are indicators that are used to know the pH of a solution.They change color as the indication of acidic or basic solution.A red litmus paper turns into blue when the solution is basic.A blue litmus paper turns red under acidic solution.
In this question the red litmus changes color to blue it means solution would be basic or alkaline.
Part 8.
The correct answer of this question is the option D which is insulin maintain the homeostasis within the body system.
Explanation:
Homeostasis is body's condition in internal equilibrium. It actually maintains the body in internal condition into dynamic equilibrium.
As the concentration of glucose increases the insulin lowers it. And as the glucose level concentration becomes too low then an hormone known as glycogen is release by pancreas which increases the glucose level in blood.
Hence all mechanism of insulin is to maintain the homeostasis in body.
Part 9.
The correct option is A.
Explanation:
A chemical compound is the combination of two or more than two different elements forming a stable compound.While an element is the combination of 2 or more than 2 same atoms.Atoms form elements and elements forms the compounds.For example C6H12O6 is a chemical compound made from 3 types of elements.While H2 is an elements.Part 10.
The option B is the correct option. Jupiter has shortest day in given planets.
Explanation:
The time period of a day of a planet depends upon its rotation around its axis.A planet with shortest time period of rotation around its axis will have shortest day.The Jupiter has shortest day. Its spinning time around its axis is 9 hr 55 min 29.69 sec.It is because Jupiter has small axial tilt of only 3.13 degrees.
1. Multiply the second line by 4: 4x+4y=16. They are the same line so there are infinitely many solutions.
2. Substitute for y.
x+(2x+10)=-2
3x+10=-2
3x=-12
x=-4
Plug x in
-4+y=-2
y=2
Final (-4,2)
3. The answer is the first one because the solution is always where two lines intersect. The crossing of the x axis, y axis, and origin are irrelevant.
4. 2x+4=3x+1. This is because both equations define the value of y and therefore must be equivalent.
5. Infinitely many solutions. If you multiply the second equation by -3, you can tell it's coinciding or the same line.
d. The pH of the beaker`s contents will decrease.
Explanation:
Since the new substance is an acid and has a very low pH, that is 1. it will reduce a little bit the pH of the original base (NaOH). Some ions of hydrogen of the acid are going to react with the hydroxyl group of the sodium hydroxide to form water.
Since the differences of the volume is big, only a small part of the base is going to be neutralize, but at the end, the final pH of the solution is still going to be a base.
Hope this information is useful.
