Answer:

The vinegar is highly acidic by 100 times than yogurt.

Explanation:

∵ pH = -log[H⁺]

  • The concentration of H⁺ in yogurt:

∵ pH = -log[H⁺]

∴ 5 =  -log[H⁺]

∴  [H⁺] = 1.0 x 10⁻⁵ M.

  • The concentration of H⁺ in vinegar:

∵ pH = -log[H⁺]

∴ 3 =  -log[H⁺]

∴  [H⁺] = 1.0 x 10⁻³ M.

the ratio of H⁺ in vinegar to that in yogurt = 1.0 x 10⁻³ M / 1.0 x 10⁻⁵ M = 100.0.

<em>∴ The vinegar is highly acidic by 100 times than yogurt.</em>

Answer:

PLEASE SOMEONE SOLVE THE QUESTION OR I'M GONNA FAIL

Explanation:

Purpose and Theory: A tablet of vitamin C contains the active ingredient called ascorbic acid (HC,H,0.).

Ascorbic acid is an organic acid which is a white power and is soluble in water.

In the following microtitration lab you will be grinding up a vitamin C tablet

, and using a 0.10 g sample of the

vitamin C powder, which will be dissolved in 20-40 mL of water. This solution will be used to determine the

quantity of ascorbic acid in a commercial vitamin C tablet.

How much heat, in calories, is given off when 1.25 grams of silver is cooled from 100.0 degrees Celsius to 80 degrees Celsius? (
lapo4ka [179]
The heat required to raise the temperature of a certain mass of sample to a specific temperature change, we use the formula mCpΔT where m is mass, Cp is the specific heat of the substance and ΔT is the temperature change. In this case, we substitute and form 1.25 g x 0.057 cal/g C *20 C equal to 1.425 calories.
