Given:
1 mole of compound synthesized from its elements
Temperature of the substances in their standard states = 25 degrees Celcius
First, gather data from reference books on the standard heats of formation of the elements. Then set up a balanced equation for the reaction. From there, calculate the heat of reaction.
Answer:
If nitrogen = 30.4% then oxygen = 100-30.4 = 69.6%
divide each % value by atomic mass
N = 30.4/14 = 2.17
O = 69.6/16 = 4.35
Divide each y smaller:
N = 2.17/2.17 = 1
O = 4.35/2.17 = 2
Explanation:
The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes
