I really hope this helped❤
Explanation:
welll, in chemistry and physics, the Avogardo constant is the number of constituent particles, usually atoms or molecules that are contained in the amount of substance given by one mole and is equal to 6.02 × 10**23. so 3 moles of carbon atoms would be 18.06 × 10**23.
The enthalpy of this reaction is -5315 KJ/mol.
The equation of the reaction is;
2C4H10(g) + 13O2(g) -----> 8CO2 (g) + 10H2O(g)
We know that the enthalpy of reaction can be obtained from the enthalpy of formation of the reactants and products as follows;
ΔHrxn = ΔHf(products) - ΔHf(reactants)
We have the following information from the question;
ΔHf C4H10 = - 125. 6 kJ/mol
ΔHf CO2 = - 393. 5 kJ/mol
ΔHf H2O = - 241. 82 kJ/mol
ΔHf O2 = 0 KJ/mol
Hence;
[(8 × (- 393. 5 )) + (10 × (- 241. 82))] - [2( - 125. 6))]
= -5315 KJ/mol

Answer: The minimum energy that a set of reactants must attain before reaction can occur
Explanation:
Chlorine is more reactive than argon, because argon is not reactive at all. Chlorine only has to gain 1 valence electron
Ionic compounds are uses ions but both uses nonmetal elements to form bonds
