Mg gained mass because it went from being a single element (on the reactant side) to being a molecule (on the product side).
Answer:
STP stands for Standard Temperature and Pressure. NTP stands for Normal Temperature and Pressure.
Explanation:
STP is set by the IUPAC as 0°C and 100 kPa or 1 bar.
NTP is set at 101.325 kPa but uses 20°C as the temperature
The enthalpy of reaction or ∆H reaction is the difference between the bond energy of the reactants and the bond energy of the products.
<h3>What is ∆H reaction?</h3>
The term ∆H reaction refers to the heat that is evolved or absorbed in a chemical reaction. It is also known as the enthalpy of reaction.
The question is incoherent but I will try to answer as much as possible. Using the values of bond energy, ∆H reaction = Bond energy of reactants - bond energy of products. This will give us the enthalpy of reaction.
