What is the pH of a solution with a POH of 8.35?

Paha777 [63]

Answer: The pH of the solution is 5.65

Explanation:

The relationship between the pH and the pOH is that $pH+pOH=14$ .

Given this, we can plug in the pOH and subtract that from 14.

$14-pOH=pH\\14-8.35=5.65$

I hope this helped! Pls give brainliest!! :)

Consider the following chemical reaction: CO (g) + 2H2(g) ↔ CH3OH(g) At equilibrium in a particular experiment, the concentratio

boyakko [2]

Answer:

The concentration of CH₃OH in equilibrium is [CH₃OH] = 2,8x10⁻¹ M

Explanation:

For the equilibrium:

CO (g) + 2H₂(g) ⇄ CH₃OH(g) keq= 14,5

Thus:

14,5 = $\frac{[CH_{3}OH]}{[CO][H_{2}]^2}$

In equilibrium, as [CO] is 0,15M and [H₂] is 0,36M:

14,5 = $\frac{[CH_{3}OH]}{[0,15][0,36]^2}$

Solving, the concentration of CH₃OH in equilibrium is:

[CH₃OH] = 0,28M ≡ 2,8x10⁻¹ M

I hope it helps!

How many molecules of HCl would react with 1 mole of Mg0? Mg0 +2HCI MgCl, + H,0

Len [333]

Answer:

12.044 ×10²³ molecules of HCl

Explanation:

Given data:

Number of moles of MgO = 1 mol

Number of molecules of HCl react = ?

Solution:

Chemical equation:

MgO + 2HCl → MgCl₂ + H₂O

with 1 mole of MgO 2 moles of HCl are react.

Number of molecules of HCl react:

1 mole contain 6.022×10²³ molecules

2 mol × 6.022×10²³ molecules / 1 mol

12.044 ×10²³ molecules
