The answer is activation energy. This is the minimum amount of energy needed to start a reaction. This is introduced by Svante Arrhenius. Also, it is the maximum amount of energy required. Activation energy can also be thought of the energy barrier.

Answer:
2.41065 grams
Explanation:
Here we have to apply molarity, particularly in reference to the equation molarity = moles of solute / volume. I would like to rewrite this formula, but with respect to the units - grams = moles / Liters,
We can use molarity to determine the number of moles. After doing so, we can determine the mass of the solute with respect to the formula moles = mass / molar mass. The molar mass of NaCl is 58.44 grams.
_______________________________________________________
275 mL = 0.275 L,
Number of Moles of NaCl = 0.150 * 0.275 = 0.04125 moles,
Mass = 0.04125 * 58.44 = 2.41065 grams,
Solution - Mass of NaCl = 2.41065 grams

Answer: Option (c) is the correct answer.
Explanation:
An equation will be balanced when both number of reactants and products are equal.
The given equation is as follows.
Number of reactants are as follows.
Number of reactants are as follows.
To balance the equation, multiply NaOH on the reactant side by 3 and on the product side by 3.
Therefore, the equation will be as follows.
The coefficient in front of NaOH is 3.
