Balance the following equations, and indicate whether they are combination, decomposition, or combustion reactions.1. c3h6(g)+o2(> co2(g)+h2o(g)1a. is it a combination reaction, decomposition reaction, or combustion reaction2. nh4no3(> n2o(g)+h2o(l)2a. is it a combination reaction, decomposition reaction, or combustion reaction3. c5h6o(l)+o2(> co2(g)+h2o(g)3a. is it a combination reaction, decomposition reaction, or combustion reaction4.n2(g)+h2(> nh3(g)? 4a. is it a combination reaction, decomposition reaction, or combustion reaction5. k2o(s)+h2o(> koh(aq)5a. is it a combination reaction, decomposition reaction, or combustion reaction

Answer :

(1) This reaction is a combustion reaction.

(2) This reaction is a decomposition reaction.

(3) This reaction is a combustion reaction.

(4) This reaction is a combination reaction.

(5) This reaction is a combination reaction.

Explanation :

Combination reaction : It is a type pf reaction in which the two or more molecules combine to form a larger single molecule as a product.

Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.

Combustion reaction : It is a type of reaction in which a hydrocarbon molecule react with the oxygen molecule to give carbon dioxide and and water as a product.

1.

i just got this problem. it's 90.3

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
