What is the [h3o+] in a solution with a poh = 5.20?

1 answer:

7 0

POH scale is used to measure how alkaline a solution is
pOH can be calculated as follows
pOH = - log [OH⁻]
pOH is 5.20 and using this the pH can be calculated
pOH + pH = 14
pH = 14 - pOH
pH = 14 - 5.20 = 8.80
pH scale is used to measure how acidic a solution is
pH = -log [H₃O⁺]
[H₃O⁺] = antilog (-8.80)
[H₃O⁺] = 1.6 x 10⁻⁹ M
answer is [H₃O⁺] = 1.6 x 10⁻⁹ M

if the climate warmed which of the following would be caused by rising temperatures? .a. an increase in sea levels. b. an increa

Klio2033 [76]

A warming climate can cause seawater to expand and ice over land to melt, both of which can cause a rise in sea level. Storm surge on a Louisiana highway shows the effects of rising sea levels. Many people are interested in climate change and how a changing climate will affect the ocean.

Answer: picture is work for # 1,2,4,5,7

Explanation: number 3: as the pressure in the volume decreases, the volume increases causing it to expand and eventually blow.

number 6: because the temperature and the amount of gas don’t change, these terms don’t appear in the equation. What Boyle’s law means is that the volume of a mass of gas is inversely proportional to its pressure. This linear relationship between pressure and volume means doubling the volume of a given mass of gas decreases its pressure by half.

hope this helps :))

What is the charge of Fe(OH)3?

klasskru [66]

The charge for this compound is positive. For Fe, it's charge is positive 3, and for OH, it's charge is negative 1. You would then criss cross the charges of each and come out with Fe(OH)3. I hope this helped!! :)
