The final concentration of the solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L is 0.35 M.
The final concentration of a solution prepared by diluting 35.0 ml of 12.0 M HCl to a final volume of 1.20 L can be calculated using the formula for dilution: M1V1 = M2V2. In this formula, M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.
Firstly, we convert the initial volume from ml to litres because the final volume is given in litres. So, 35.0 ml = 0.035 L. Therefore, the equation becomes: 12.0 M * 0.035 L = M2 * 1.20 L.
On rearranging the equation to solve for M2, the result is 0.35 M.

Answer:
4
Explanation:
The concentration of a solid or a liquid is essentially constant at equilibrium, because the forward and reverse reaction rates are equal.

Answer: The given statement is true.
Explanation:
When solid state of water changes directly into vapor state then this process is known as sublimation.
For example, when dry ice is placed at room temperature then it converts into vapor state without undergoing liquid state.
Also when we apply very high pressure or temperature at the solid state of water, it will change directly into vapor state.
Therefore, the statement ice does not need to melt into liquid water before it can return to the atmosphere as water vapor is true.
