A known mass of MgCO3 heated and 100cm3 of CO2 is collected at 27°C and at
a pressure of 100kPa. Calculate the mass of:
i. CO2 produced
ii. the orginal carbonate heated
[Mg=24.0, 0 = 16.0, C=12.0 R = 8.3kPadm3K-¹mol-¹ K-¹]

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
