What factor affects the solubility of all solutes, whether solid, liquid, and gaseous? -pressure -temperature -volume -number of

moles -all of the above

Answer:

temperature

Explanation:

The solubility is the maximum amount of the substance that will be dissolved in water given the amount of the solvent at a specif temperatures and thus there are factors in which the solubility depends as the temperatures.

The temperature affects the solids and liquids and pressure the gases. The <u>solubility </u>of the <u>organic compounds also increases with temperature changes.</u>

For a particular isomer of C8H18, the combustion reaction produces 5113.3 kJ of heat per mole of C8H18(g) consumed, under standa

mart [117]

Answer: The standard enthalpy of formation of this isomer of $C_8H_{18}(g)$ is -210.9 kJ

Explanation:

The given balanced chemical reaction is,

$C_8H_{18}(g)+\frac{25}{2}O_2(g)\rightarrow 8CO_2(g)+9H_2O(g)$

First we have to calculate the enthalpy of formation of $C_8H_{18}$ .

$\Delta H^o=H_f_{product}-H_f_{reactant}$

$\Delta H^o=[n_{CO_2}\times \Delta H_f^0_{(CO_2)}+n_{H_2O}\times \Delta H_f^0_{(H_2O)}]-[n_{O_2}\times \Delta H_f^0_{(O_2)+n_{C_8H_{18}}\times \Delta H_f^0_{(C_8H_{18})}]$

where,

We are given:

$\Delta H^o_f_{(CO_2(g))}=-393.5kJ/mol\\\Delta H^o_f_{(H_2O(g))}=-241.8kJ/mol\\\Delta H^o_f_{(O_2(g)))}=0kJ/mol$

Putting values in above equation, we get:

$-511.3kJ/mol=[(8\times -393.5)+(9\times -241.8)]-[(\frac{25}{2}\times 0)+(1\times \Delta H_f^0_{(C_8H_{18})}$

$\Delta H_f^0_{(C_8H_{18})}=-210.9kJ$

What is the significance of the fact that the droplets carried different charges?

Sindrei [870]

The charges on a droplet can be used to represent the number of electrons carried by this droplet.
In other words:
a droplet having a charge of 1.60 x 10^-19 has 1.60 x 10^-19 electrons while a droplet having a charge of 3.15 x 10^-19 has <span>3.15 x 10^-19 electrons.

From the observations:
The fact that the droplets carried different charges signifies the fact the different droplets carried different numbers of electrons</span>
