Answer:

Reducing the amount of vinegar will reduce the amount of carbon dioxide produced because there will be fewer molecules of acetic acid to react with the baking soda and produce the carbon dioxide.

To make more carbon dioxide, you could add either more acetic acid or more sodium bicarbonate or more of both.

The p K a of hypochlorous acid is 7.530 . A 60.0 mL solution of 0.103 M sodium hypochlorite ( NaOCl ) is titrated with 0.296 M H
IrinaVladis [17]

Answer:

pH of the solution after addition of 8 ml 0,296 molar HCl = 7.94

Explanation:

In this case buffer exist between hypochlorous acid HClO is a weak acid and its conjugate base hypochlorite ion ClO⁻ which are deliver to the solution by NaOCl ( sodium hypochlorite ).

The salt is completely dissociate

                     [NaOCl] = [ClO⁻]

Using Henderson equation to find pH of this buffer

            pH = pKa + log\frac{[Conjugate base]}{[Acid]}

or,               = 7.53  + log\frac{60 X 0.103}{8 X 0.296}

or,               = 7.53 + 0.4

or,               = 7.94

How much energy is gained when a 10.0g sample of liquid water increases in temperature from 13°C to 18°C?
Ivan

When a 10g sample of liquid water increases in temperature from 13°C to 18°C, then the amount of gained energy is 209 joules.

<h3>How do we calculate gained energy?</h3>

The amount of energy which is gained by any sample will be calculated as:

Q = mcΔT, where

Q = gained energy

m = mass of sample = 10g

c = specific heat of water = 4.18 J/g°C

ΔT = change in temperature = 18 - 13 = 5°C

On putting values we get

Q = (10)(4.18)(5)

Q = 209 Joules

Hence required amount of energy is 209 joules.
