The answer is 12.5 mL.
Solution:
<u>M, 6.00M V₁ =?</u>
M2 = 3.00M, V₂ = 25.0mL
<u>M1V1 = M2 V2/M1</u>
V1 = M2V2 M,
V1 = 25.0X3.00/6.00
∴ V1 = 12.5 mL
The initial concentration of the resulting solution is 2 molar which is the volume multiplied by the concentration. The volume of the starting solution is therefore 2,500 ml × 2.25 mol. Calculate the number of moles of HCl dissolved in a given volume of acid by reacting an acid with CaCO3.
This is essentially a double exchange reaction with the decomposition of one of the products. To determine the amount of stock solution required divide the number of moles of glucose by the molarity of the stock solution.

C. Liquid. The Earth is mostly water, namely ocean water which is liquid.
Answer:
a) The metal with the higher heat capacity.
Explanation:
The heat (Q) absorbed by a metal can be calculated using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the metal
m is the mass of the metal
ΔT is the change in the temperature
Q = c × m × ΔT
ΔT = Q/ c × m
Considering both metals have equal mass (m) and are subject to the same amount of heat (Q), the change in the temperature is inversely proportional to the specific heat capacity. The metal with the higher specific heat capacity will undergo the smallest change in temperature.
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
