The given statement about standard heat of formation is true.
Explanation:
Yes, it is true that standard heat of formation is same as standard enthalpy of formation. As enthalpy is termed for change in the heat energy occurred in the process of completion of any chemical reaction, the standard enthalpy or heat of formation is termed as the heat energy required to form 1 mole of any substance in its standard state from its original, parent or constituent elements in their standard state. Basically, it defines the amount of energy required by the system or compound for its formation from different elements under different synthesis conditions but the nature of the parent samples and temperature and pressure should be kept standard.
So the given statement is true.
I believe the correct answer from the choices listed above is option A. The reactant for the given chemical reaction would be NaHCO3 and HCl. <span>A </span>reactant<span> is a substance that changes in a chemical reaction. It is the starting material in a reaction. Hope this answers the question.</span>
Single replacement, one atom takes the place of another. There’s one element and one compound and they switch
element + compound —> (and then either the +ions switch with each other or the -ions)
A+BC—> AC + B
