  1. 1) Although it is often claimed that Christians were persecuted for their refusal to worship the emperor, general dislike for Christians likely arose from their refusal to worship the gods or take part in sacrifice, which was expected of those living in the Roman Empire.
    2)Roman Religion Challenged. Judaism and Christianity, while posing separate threats to the empire, had one thing in common - they both refused to participate in the worship of the Roman gods and make sacrifices at their temples.
    3) Islam, Judaism

  2. 1.One of the reasons was that Jesus' followers called Jesus God which proved poorly because the only one who was allowed to be called God was the emperor.
    3.Christianity, Judaism, and Islam

  3. 6). the presence of caffeine on the worm's skin

    7). the worm's heart-rate

    8). "Dripping caffeine on a worm's skin causes the worm's heart to beat faster."

    (Note: The things she observed suggest but do not PROVE that this hypothesis is true.)

  4. (A) is 0.0773 mol B2H6

    (C) is 2.79 x 10^23 H atoms


    Questions (A) and (B) are the same.

    2.14 g B2H6 x (1 mol B2H6/27.668g B2H6) = 0.0773 mol B2H6 (A)

    27.668 is the molar mass of B2H6 calculated from the period table:

    (2 x 10.81) + (6 x 1.008) = 27.668

    1.008 is the mass of H and 10.81 is the mass of B


    0.0773 mol B2H6 x (6 mol H/ 1 mol B2H6) x (6.022 x 10^23 H atoms/1 mol H)

    = 2.79 x 10^23 hydrogen atoms

    Further Explanation:

    For every 1 mol of B2H6, there are 6 moles of H (indicated by the subscript)6.022 x 10^23 is Avogrado's number and it equals to 1 mol of anything Avogrado's number can be in units of atoms, molecules, or particles

  5. 1, neutralization of hydrochloric acid with sodium hydroxide 
    ,2. balanced 

    3. reactants are sodium hydroxide also called lye and hydrochloric acid which as a gas is hydrogen chloride, also stomach acid 
    products are water and sodium chloride, also called table salt

  6. 1.Water's polarity allows it to dissolve other polar substances  easily. When a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa. ... The dissolving power of water is very important for life on Earth.2.The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.3.Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Also, water is called the "universal solvent" because it dissolves more substances than any other liquid. This is important to every living thing on earth.

  7. 3.   5x-3 = 13 -3x                                                                                                                        5x + 3x = 3 + 13                                                                                                                             2x  =  10                                                                                                                                                    x = 10/2                                                                                                                                                       x =  5
