Answer:

pOH = 5.23

Explanation:

<u>Given:</u>

H+ concentration = 1.7*10⁻⁹ M

<u>To determine:</u>

pOH of the solution

<u>Explanation:</u>

pH and pOH measure the H+ and OH- ion concentrations respectively in a given solution and thereby reflect the degree of acidity and basicity of the solution.

pH and pOH are related as follows:

pH + pOH = 14\\\\pH = -log[H+]\\\\For\ the\ given\ solution\\\\pH = -log(1.7*10^{-9}) = 8.77\\\\Therefore:\\\\pOH = 14.0 - pH = 14.0 -8.77 = 5.23

PH = -log[H+]
pH = -log[1,7×10^-9]
pH = 8,77

pH + pOH = 14
pOH = 14 - 8,77
pOH = 5,23

1. How many moles of CO2 can be produced from a reaction of 10.0 moles CzHg?
mr_godi [17]

Answer:

20 moles of CO2 can be produced from a reaction of 10.0 moles C2H6

Explanation:

In this reaction -

2 moles of C₂H6 produces four molecules of Carbon dioxide (CO2)

So 1 mole of C₂H6 will produce \frac{4}{2} = 2 moles of Carbon dioxide (CO2)

Thus, 10 moles of C₂H6 will produce 2 * 10 = 20 moles of Carbon dioxide (CO2)

Answer:

As a substance changes from a solid to a liquid to a gas, its molecules first the molecules are moving fast enough, they are able to "escape." They leave the surface of the liquid as gas molecules. Evaporation is not the only process that can change a substance from a liquid to a gas. The same change can occur through boiling.
