Im a freshman in highschool pls how many hydrogen and oxygen are in 1 molecule of h2o2 hydrogen peroxide 2) how many atoms of aluminum sulfur and oxygen are in 1 molecule of aluminum sulfate al2(so4)3 3) how many atoms of hydrogen and oxygen are in 2 molecules of water 4) how many atoms of hydrogen and oxygen are in 8 molecules of hydrogen peroxide5) how many atoms of aluminum sulfur and oxygen are in 3 molecules of aluminum spare 6) how would you indicate 2 water molecules using chemical symbols 7) using complete sentences explain the difference between the chemical formulas shown 4 h2o and h8o4

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

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.
