Answer:

The answer is D - near the roof.

Explanation:

Attics don't have a ton of insulation or hard cinder-block to block the goggles form seeing through it. This is why the attic can be a place where the temperature varies with the outside temperature.

What is the pH of a solution with a concentration of 1.8 × 10-4 molar H3O+?

Andre45 [30]

PH is defined as the negative log of Hydrogen ion concentration. Mathematically we can write this as:

$pH=-log[H^{+}]=-log[H_{3}O]$

We are given the concentration of $H_{3}O$ . Using the value in formula, we get:

$pH=-log[1.8*10^{-4}]=3.745$

Therefore, the pH of the solution will be 3.745

Suppose 0.035 moles of HCl is dissolved in enough water to produce 750 mL of solution. What is the pH

zhuklara [117]

Answer:

pH = 1.33

Explanation:

Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.

Now we calculate the molar concentration (molarity) of H⁺:

Molarity = moles / volume

(750 mL ⇒ 750 / 1000 = 0.750 L)

Molarity = 0.035 moles / 0.750 L

Molarity = 0.0467 M

Then we calculate the pH of the solution:

pH = -log [H⁺]

pH = -log (0.0467 M)

pH = 1.33
