Answer:
Option B. 25mL
Explanation:
Step 1:
Data obtained from the question:
Molarity of stock solution (M1) = 6M
Volume of stock solution needed (V1) =..?
Molarity of the diluted solution (M2) = 0.5M
Volume of diluted solution (V2) = 300mL
Step 2:
Determination of the volume of the stock solution needed.
Using the dilution formula, we can easily find the volume of the stock solution needed as follow:
M1V1 = M2V2
6 x V1 = 0.5 x 300
Divide both side by 6
V1 = (0.5 x 300) /6
V1 = 25mL
Therefore, 25mL of 6M NaOH is needed.
Solubility<span> is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It has units of grams of the substance per grams of solvent. We calculate the mass as follows:
311 g AgNO3 / 100 g water (350 g water) = 1088.5 g AgNO3
It can be rounded of to 1100 g of AgNO3. Therefore, option B is the correct answer.</span>

Ionic i believe, they have high melting point
The correct answer is a.) C. Oxidation occurs when an element loses electrons and increases its oxidation state. In the chemical equation, Carbon in CH4 has an oxidation state of 4- while Carbon in CO2 has an oxidation of 4+.
