Write a detailed paragraph about how a volcano is formed. be sure to include how density, convection currents, and plate tectonics all come
together to make a volcano.

okay but give me brainliest

Explanation:

A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Volcanic flows are called lahars.

First step is always balance the equation:
n2h4 + 7 h2o2 --> 2hno3 + 8h2o 

so assuming that n2h4 is in excess and only moles of h2o2 are determining the product content then 7 moles of h2o2 give 2 moles of hno3
so:
7: 2
x: 0.08
x=0.28 moles of h2o2
