Answer: Option (4) is the correct answer.
Explanation:
When sulfuric acid reacts with calcium hydroxide then it results in the formation of calcium sulfate and water.
The chemical reaction for the same will be as follows.
Thus, we can conclude that 
salt is produced when sulfuric acid and calcium hydroxide react completely.
Answer:
molarity of the KI solution = 0.04 mol/L
Explanation:
Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution.
The law that we can applied to calculate the M is:
M = n / V
n - number of moles
V- volume of the solution (liters)
Then insert in the equation the values from the question;
M = 0.082 mol / 2.03 L = 0.04 mol/L
The answer for it is C. when you mix it with water it fizzes
Answer:
Distance
Explanation:
The light-year is a measure of distance, not time. It is the total distance that a beam of light, moving in a straight line, travels in one year.
