For balancing acidic solutions, we would need to add H+ ions to the correct side of the equation to balance the total number of atoms and the overall charge.
<h2>Answer:</h2>
<em>8.67kJ/mol</em>
<h2>Explanations</h2>
The formula for calculating the amount of heat absorbed by the water is given as:

Determine the moles of KI

Since heat is lost, hence the enthalpy change of the solution will be negative that is:

Determine the enthalpy of solution in kJ•mol-1

Hence the enthalpy of solution in kJ•mol-1 for KI is 8.67kJ/mol
Answer:
Correct option: <em>3</em>
Explanation:
A basic oxide is an oxide that reacts with water to give base or reacts with acid to form salt
eg:
Sodium oxide reacts with water to produce sodium hydroxide.
Magnesium oxide gives magnesium chloride on reaction with hydrochloric acid
An acidic oxide is an oxide that reacts with water to give acid and reacts with base to give salt.
eg: Carbon dioxide gives carbonic acid on reaction with water .
Sulfur dioxide gives sulfites when reacs reacts with bases.
An amphoteric oxide is an oxide which reacts with base as well acid and it shows because metal have multiple oxidation state and they can form oxide as well hydroxide
