One day in lab, while taking apart a complicated distillation apparatus, your friend Dan (an expert chemist) says this: "Metal sulfides react with strong acids to produce hydrogen sulfide and a salt." Using Dan's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! Fe $3(s) + HNO3(aq) → I 0-0

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.

answer: they produce more slow than unicellular organisms.
