Potassium sulfate is added to water. The equation that best represents this process

Chemistry
1 answer:
Anastaziya [24]2 years ago
5 0

The equation that best represents the addition of potassium sulfate to water is K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)

<h3>Dissolution of potassium sulfate in water</h3>

When potassium sulfate is dissolved in water, it dissociates into its cation and anion according to the following equation:

K_2SO_4(s) -- > 2 K^+ (aq) + SO4^{2-} (aq)

The positive ions are 2 moles of potassium ions while the negative ion is a mole of sulfate ion.

A rock that has a mass if 180 grams dropped in a graduated cylinder that was originally filled to 52ml; it now reads 62ml. What
Vlad [161]

Answer:

<h2>18 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

volume = final volume of water - initial volume of water

volume = 62 - 52 = 10 mL

From the question we have

density =  \frac{180}{10}  \\

We have the final answer as

<h3>18 g/mL</h3>

Hope this helps you

In the reaction of magnesium with oxygen, explain which atom is the reducing agent.
Mnenie [13.5K]

Answer:

Mg.

Explanation:

  • The oxidation-reduction reaction contains a reductant and an oxidant (oxidizing agent).
  • An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.
  • A reducing agent (also called a reductant or reducer) is an element (such as calcium) or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.
  • For the reaction:

<em>Mg + 1/2O₂ → MgO.</em>

<em></em>

Mg is oxidized to Mg²⁺ in (MgO) (loses 2 electrons). "reducing agent".

O is reduced to O²⁻ in (MgO) (gains 2 electrons). "oxidizing agent".
