C2H2, or acetylene, has a molar mass of 26g. That means it has 113/26 = around 4.34 mols. Assuming complete combustion, the balanced equation comes out to this:
C2H2 + 3O2 --> 2H2O + 2CO2
Using the molar ratios, we get that we get 8.68 mols of water for every 4.34 mols, so since the molar mass of water is 18 grams per mol, we multiply 18 * 8.68 = about 156.24 grams.
To change solar energy to chemical energy is the answer!
Because the number of protons defines what that element is.
Answer:
-1043,8 KJ
Explanation:
Hello!
It is necessary to accommodate the reactions to get the reaction of my interest.
Reaction A reverses what modifies its energy in its sign (+72.6 KJ).
Reaction B doubles, which also doubles its energy (-514.4 KJ x 2).
Reaction C reverses what modifies its energy in its sign (-87.6 KJ).
By sum of the energies I get the energy of the global reaction.
