A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).

<h3>How can we determine the acidity or basicity of a solution?</h3>

If pH < 7, the solution is acid.
If pH = 7, the solution is neutral.
If pH > 7, the solution is basic.

Step 1. Calculate the pOH of the solution.

The hydroxide ion concentration is 2.5 × 10⁻⁴ mol/L.

pOH = -log [OH⁻] = log (2.5 × 10⁻⁴) = 3.6

Step 2. Calculate the pH of the solution.

We will use the following expression.

pH + pOH = 14

pH = 14 - pOH = 14 - 3.6 = 10.4

Since pH > 7, the solution is basic.

A cleaning solution with an OH⁻ concentration of 2.5 × 10⁻⁴ mol/L, has a pH of 10.4 and is basic (options b and c).

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press

Simora [160]

Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

$P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L$

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

Have a nice day!

If a car jack's output force is 1000 N and the mechanical advantage is 6.8, what is the input force?

Travka [436]

Answer
147.06N
Explanation:
MA=Load/Effort
6.8=1000/x
Finding x you make x the subject and divide 1000 by 6.8 which is 147.06N

1. Which statements represent properties of intermolecular forces? Select all that apply.

kumpel [21]

Answer:

Explanation:

Only this choice is applicable and correct.

The inter-molecular forces of attraction between the molecules must have been broken (overcome) before the molecules can gain an increase in the kinetic energies between them.
