Magnesium nitride is formed in the reaction of magnesium metal with nitrogen gas in this reaction: 3 mg(s) + n2(g)  mg3n2(s) how many grams of product are formed from 2.0 mol of n2 (g) and 8.0 mol of mg(s)? show all calculations leading to an answer.

the answer is b. dilution

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.

the objects have the same charge.
