Answer:

n_{H_2O}=16molH_2O

Explanation:

Hello,

In this case, given the properly balanced reaction:

CH_3OH+\frac{3}{2} O_2\rightarrow CO_2+2H_2O

If 8.0 moles of methanol react, we can compute the produced grams of water by noticing the 1:2 molar ratio between them in the chemical reaction (stoichiometric coefficients):

n_{H_2O}=8molCH_3OH*\frac{2molH_2O}{1molCH_3OH} \\\\n_{H_2O}=16molH_2O

Best regards.

Explain why the process of dissolution can be exothermic or endothermic (heat of solution) with different solutes
RUDIKE [14]

Answer:

The process of dissolving is exothermic when more energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because more energy is released than is used, the molecules of the solution move faster, making the temperature increase.

Project the image Endothermic Dissolving.

The process of dissolving is endothermic when less energy is released when water molecules “bond” to the solute than is used to pull the solute apart. Because less energy is released than is used, the molecules of the solution move more slowly, making the temperature decrease.

dusya [7]
A) At 0 C water forms ice but as mentioned above F) water's greatest density occurs at 4 C and it decreases below 4 C so ice is lighter than 4C water, thus, at 0C ice comes to surface and acts as insulator thereby preventing lower water from freezing.
