The answer is C. an endothermic reaction. The endothermic reaction means this reaction will absorb energy and exothermic reaction means this reaction will release energy.
Answer:
1.25 mol LiF
Explanation:
5.00 M solution means
5.00 mol LiF in 1 L solution=1000mL
x mol LiF in 250 mL
x = 5.00*250/1000 = 1.25 mol LiF
1066.7 ml of the stock solution must start with, preparing 2.00 L of a 0.800 M NaNO3 solution.
<h3>What is volume?</h3>
Volume is the space occupied by a three-dimensional object.
By the formula 
M1 is the initial molarity, 1.5 M
M2 is the final molarity, 0.800 M
V1 is the initial volume
V2 is the final volume, 2.00 L
Putting the values in the equation
Thus, the initial volume is 1066.7 ml

Explanation:
Answer:
The Enthalpy of neutralization
Explanation:
The reaction of a base (KOH) with an acid (HCl) produce water and its salt (KCl) is called <em>Neutralization Reaction.</em>
This neutralization releases 57kJ/mol.
As the type of enthalpy is due the type of reaction. This enthalpy is:
<h3>The Enthalpy of neutralization</h3>
