Is n2+ h2→nh4 a balanced chemical equation? is it obeying the law of conservation of matter? A. no the equation us not balanced. hydrogen is not balanced but nitrogen is balanced

B. Yes, the equation is balanced

C. no, the equation is not balanced, they both are not balanced

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 answer is true. hope it .
