In balancing reactions, the number of atoms on each side should be of equal number. It is the most important rule in reactions. Also, we should know the correct substances involved in the reaction. We do as follows:
2K + MgBr2 = 2KBr + Mg
You multiply 32 by 2, since there are two hydrogens in every water molecule.
The answer is; D
Enthalpy is the system’s internal energy ( considering the product of its pressure and volume). When the enthalpy is negative, it means that the products have a lower energy level than the reactants - meaning the system has dispensed some energy into the environment.
Creep is somthing you might call somone following you. Example, "he was slowly creeping up the stairs behind me". A land slide normally moves faster then that.
