KOH -------------> K⁺   +  OH⁻

pOH = - log [ OH⁻ ]

pOH = - log [ 1 x 10⁻⁵ ]

pOH =  5

pH + pOH = 14

pH + 5 = 14

pH = 14 - 5

pH = 9

hope this helps!

A loaded coal wagon with a total mass of 20 000 kg is pushed by a force of 300 000 N. What was the wagon’s acceleration?
AlexFokin [52]

Answer:

<h2>15 m/s²</h2>

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a =  \frac{f}{m}  \\

f is the force

m is the mass

From the question we have

a =  \frac{300000}{20000}  =  \frac{30}{2}  \\

We have the final answer as

<h3>15 m/s²</h3>

Hope this helps you
