Density is mass divided by volume
So...
D = 8/25 = 0.32 g/cm^3

Do the formula <span>D = m/v </span>

d = ( 8.0 grams ) / ( 25 c ) 

d = 0.32 grams / c

<span>d = ( 0.32 g / c ) ( 1.0 x 10^6 c / c ) ( 1 kg / 1000 kg ) </span>

d = 320 kg / c

The answer is choice C. <span>✅</span>

Match the salt with the acid and base used to form it in a neutralizing reaction. K2SO4
emmasim [6.3K]

Answer:

KOH and H₂SO₄

Explanation:

Neutralization reaction:

It is the reaction in which acid and base react with each other and produce salt and water.

For example:

2KOH + H₂SO₄  →   K₂SO₄ + 2H₂O

1. Potassium hydroxide and sulfuric acid react to produce potassium sulfate salt and water.

2. Potassium hydroxide and phosphoric acid react to produce potassium phosphate and water.

H₃PO₄  + 3KOH  → K₃PO₄ + 3H₂O

3. Phosphoric acid sodium hydroxide react to produce sodium phosphate and water.

H₃PO₄  + 3NaOH   → Na₃PO₄ + 3H₂O
