Calculate the pOH for a solution with h3o 2.5x10-5 g?

Mathematics
1 answer:
topjm [15]2 years ago
8 0

Answer:

pOH = 9.4

Step-by-step explanation:

Mathematically;

pH + pOH = 14

pOH = 14 - pH

But pH = -log[H3O+]

From the question [H3O+] = 2.5 * 10^-5

Thus pH = -log (2.5 * 10^-5)

pH = 4.6

Thus;

pOH = 14-4.6

pOH = 9.4

If you want to put a 4x8 piece of plywood through a 3 foot square opening in your ceiling by turning it diagonally is the openin
Zigmanuir [339]
Here we apply the Pythagorean theorem:
c^2=a^2+b^2
The diagonal of the opening will be:
c^2=3^2+3^2
c^2=9+9
c^2=18
c=3√2 ft

The diagonal of the wood will be:
c^2=4^2+8^2
c^2=16+64
c^2=80
c=4√5 ft

The space will not be enough for the plywood to pass

Solve the following equation for x: 5x + 3y = 15.
Blizzard [7]

Answer:

x = negative three fifthsy + 3

Step-by-step explanation:

5x + 3y = 15

Subtract 3y from both the sides,

5x = 15 - 3y

Divide by 5 on both sides,

x = -3y/5 + 15/5

x = -3y/5 + 3
