Answer: Product
Explanation:
A Chemical reaction shows how substances, written in symbols known as reactants, are converted to different substances called products. An arrow from the left hand side (reactants) points to right hand side ( products )shows the direction of flow of reaction.
In the equation. C + O2 --------> CO2
reactant------> product
CO2 is the product
Answer:
In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons. That is, the atoms share one pair of electrons where the bond forms. Therefore, a single bond is a type of covalent bond.

Answer: Th enthalpy of combustion for the given reaction is 594.244 kJ/mol
Explanation: Enthalpy of combustion is defined as the decomposition of a substance in the presence of oxygen gas.
W are given a chemical reaction:
![Mg(s)+\frac{1}{2}O_2(g)\rightarrow MgO(s)](https://tex.z-dn.net/?f=Mg%28s%29%2B%5Cfrac%7B1%7D%7B2%7DO_2%28g%29%5Crightarrow%20MgO%28s%29)
![c=5760J/^oC](https://tex.z-dn.net/?f=c%3D5760J%2F%5EoC)
![\Delta T=0.570^oC](https://tex.z-dn.net/?f=%5CDelta%20T%3D0.570%5EoC)
To calculate the enthalpy change, we use the formula:
![\Delta H=c\Delta T\\\\\Delta H=5760J/^oC\times 0.570^oC=3283.2J](https://tex.z-dn.net/?f=%5CDelta%20H%3Dc%5CDelta%20T%5C%5C%5C%5C%5CDelta%20H%3D5760J%2F%5EoC%5Ctimes%200.570%5EoC%3D3283.2J)
This is the amount of energy released when 0.1326 grams of sample was burned.
So, energy released when 1 gram of sample was burned is = ![\frac{3283.2J}{0.1326g}=24760.181J/g](https://tex.z-dn.net/?f=%5Cfrac%7B3283.2J%7D%7B0.1326g%7D%3D24760.181J%2Fg)
Energy 1 mole of magnesium is being combusted, so to calculate the energy released when 1 mole of magnesium ( that is 24 g/mol of magnesium) is being combusted will be:
![\Delta H=24760.181J/g\times 24g/mol\\\\\Delta H=594244.3J/mol\\\\\Delta H=594.244kJ/mol](https://tex.z-dn.net/?f=%5CDelta%20H%3D24760.181J%2Fg%5Ctimes%2024g%2Fmol%5C%5C%5C%5C%5CDelta%20H%3D594244.3J%2Fmol%5C%5C%5C%5C%5CDelta%20H%3D594.244kJ%2Fmol)
