The molarity of the diluted solution is 0.2706 M.
Given,
M₁ = 1.1 M
V₁ = 123 mL
V₂ = 500.0 mL
The dilution law formula is M₁V₁ = M₂V₂
1.1*123=M₂*500
M₂=0.2706 M
<h3 /><h3>Molarity </h3>
Molarity, a concentration unit used in chemistry, is determined by dividing the number of moles of a solute by the number of liters of solution. The phrase "molar concentration" (also known as "molarity," "amount concentration," or "substance concentration") refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution. The most frequent measure of molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units. A solution with a concentration of 1 mol/L is referred to as 1 molar, or 1 M.

Answer:
HCN - Hydrogen cyanide The conjugate acid of CN- is HCN. HCN stands for hydrogen cyanide. The conjugate acids are a combination of a strong acid and a low base.
Answer:
C
Explanation:
It is letter C since you are currently experimenting to see if by the amount of rainfall it gets it can <em><u>grow</u></em><em><u> </u></em><em><u>more</u></em><em><u> </u></em><em><u>or</u></em><em><u> </u></em><em><u>less</u></em>. So you control the amount of rain
Answer:
How much energy would be produced from the reaction of 2.40 moles hydrogen with 3.95 moles chlorine?
Explanation:
Given,
2.40 moles hydrogen reacts with 3.95 moles chlorine.
From the balanced chemical equation,
1mol. of H2 reacts with 1mol. of Cl2
then,
2.40mol. of H2 reacts with ----?mol of Cl2
So, the remaining moles of Cl2 is in excess.
The limiting reagent is--- H2.
1mol. of H2 releases --- 554kJ of energy
then,
2.40mol of H2 releases ---- ?
Answer is: deltaH =-1329.6kJ
