When you burn wood in a campfire, _ energy is converted to _ and light energy.

when you burn wood in a campfire, chemical energy is converted to heat and light energy.

Explanation :

When wood is burned stored potential energy ( in the form of chemical energy ) in the log is released due to heating by other excited atoms . This process is called combustion and requires presence of oxygen. So,  combustion can be defined as a process which changes chemical energy into kinetic energy in the form of heat.  In case of combustion  an organic say wood in this case combines with oxygen present in the atmosphere to give off carbon dioxide, water and energy in the form of heat and light .    

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
