One half of a balanced chemical equation is shown. 3mg(oh)2 + 2h3po4 which lists the numbers of each atom the other half of the equation would contain?
a. 3 mg, 2 p, 14 o, 12 h
b. mg, 2 p, 14 o, 6 h
c. 3 mg, 8 p, 7 o, 6 h
d. 6 mg, 6 p, 2 o, 12 h

a. hope i'm right

explanation:

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

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.
