balance the following chemical equations. make sure you capitalize appropriately.
hcl → h₂ + cl₂
so₃ → so₂ + o₂
ch₃oh → co + h₂
c + o₂ → co
so₂ + h₂ → h₂s + h₂o

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
