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:
KOH is a strong base, and therefore dissociates completely into negative and positive ions in water solution. pH 8.35 is a high pH (> 7), therefore this is a basic solution. 4.
Explanation:
Fluorine and element M combine to create the ionic compound with the formula 
electrons make up the M cation. Sn is the element M.
<h3>
What is an ionic compound, how is it made, and an example?</h3>
A compound known as an ionic compound is one that is created when two oppositely charged ions come together to form a chemical bond, such as sodium chloride.
When an atom (or collection of atoms) gains or loses electrons, it produces ions, which are charged particles. Ionic compounds are substances made of ions. (A positively charged ion is a cation, whereas a negatively charged ion is an anion.) When elements share electrons in a covalent connection to create molecules, they produce covalent or molecular compounds.
