Answer:

A nonelectrolyte is a substance that does not exist in an ionic form in aqueous solution. Nonelectrolytes tend to be poor electrical conductors and don't readily dissociate into ions when melted or dissolved. Solutions of nonelectrolytes do not conduct electricity.

Which quantity is constant when working with boyles, charles, and gay lussacs law?

oee [108]

boyles law states that the volumes of a gas will decrease as pressure increases if the temperature remains constant.

charles law states that the volume of a gas will increase as temp increases if the pressure remains constant.

gay-lussacs law states that the pressure increases as temp increases if the volume remains constant.

The equation below represents a double replacement/displacement reaction;

Naddik [55]

AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!

When sodium carbonate is dissolved in water, the equation is $Na_2CO_3 (s) --- > 2Na^+ (aq) + CO_3^{2-} (aq)$ .

When carbon dioxide is placed in water, aqueous carbon dioxide is formed: $CO_2 (g) --- > CO_2(aq)$

<h3>Dissolution of compounds in water</h3>

Some compounds are water-soluble, some are just partially soluble, while others are insoluble in water. Some soluble or partially soluble substances dissociate in water into their component ions. These substances are said to be ionic.

Sodium carbonate, like every other sodium salt, is soluble in water. It dissolves in water to form an aqueous solution of sodium carbonate.

While in solution, sodium carbonate dissociates into its component ions according to the following equation:

$Na_2CO_3 (s) --- > 2Na^+ (aq) + CO_3^{2-} (aq)$

Carbon dioxide, on the other hand, does not dissociate in water. Instead, it dissolves in water where most of it remains as aqueous carbon dioxide in equilibrium with a small amount of hydronium ion and hydrogen carbonate ion.

Since the hydronium and hydrogen carbonate ions formed are so minute, the equation of the reaction can be written as: $CO_2 (g) --- > CO_2(aq)$

Which of the following compounds are soluble in aqueous solutions? Select ALL that are soluble.

sattari [20]

<h3>Answer:</h3>

K₂S
CaSO₄ (slightly soluble in water)
Pb(ClO₄)₂

<h3>Explanation:</h3>

Mg(OH)₂ and CoCO₃ are insoluble in water.
Solubility rules are used to determine whether a compound will be soluble or not soluble in aqueous form.
K₂S is soluble in aqueous solutions as all salts of Potassium are soluble in water.

Calcium (ii) sulfate is slightly soluble in water.
Hydroxides are insoluble in water except, KOH, NaOH and NH₄OH.and Barium hydroxide. Therefore, Mg(OH)₂ is an insoluble hydroxide.

CoCO₃ is insoluble since carbonates are insoluble except K₂CO₃, Na₂CO₃ and (NH₄)₂CO₃. .

Pb(ClO₄)₂ is soluble because all perchlorates are soluble.
