How does temperature affect the vapor pressure of a liquid?

1 answer:

3 0

Answer:

As the temperature of a liquid increases, the kinetic energy of its molecules also increases. As the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.

an aqueous solution contains 1.2mM of total ions. if the solution is NaCl (aq), what is the concentration of chloride ions?

Genrish500 [490]

Explanation:

As the total concentration is given as 1.2 mM. And, it is also given that salt present in the solution is NaCl.

As sodium chloride is an ionic compound so, when it is added to water then it will dissociate into sodium and chlorine ions as follows.

$NaCl \rightarrow Na^{+} + Cl^{-}$

So, it means in total there will be formation of 2 ions when one molecules of NaCl dissociates.

Therefore, concentration of chlorine ions will be calculated as follows.

Concentration of $Cl^{-}$ ions = $\frac{1.2mM}{2}$

= 0.6 mM

Thus, we can conclude that the concentration of chloride ions is 0.6 mM.

The complete balanced equation for the reaction between barium hydroxide and acetic<br> acid is

TiliK225 [7]

Answer:

2 CH3COOH + Ba(OH)2 --> Ba(C2H3O2)2 + 2H2O

To make it less clustered, you can use Ac for C2H3O2.

2 HAc + Ba(OH)2 --> Ba(Ac)2 + 2H2O

The acetic acid reacts with the base barium hydroxide to form the salt barium acetate and water.

Explanation:

final answer. C
