Anh measured the temperature of a pond near his house. Before he left for school, the water in the pond was 18 degrees celsius.
Hitman42 [59]

As the temperature increases, B) the molecules started moving faster.

Explanation:

The temperature of a substance is a measure of the average kinetic energy of the particles in a substance. In particular, it can be found that the temperature is directly proportional to the average kinetic energy of the particles:

T\propto KE

The kinetic energy of a particle is given by

KE=\frac{1}{2}mv^2

where

m is the mass of the particle

v is its speed

This means that the higher the temperature of a substance, the greater the speed of the particles in the substance.

Therefore, if we apply this concept to this problem, we infer that as the temperature of the water in the pond gets higher, the speed of the molecules inside the water increases, which means that the molecules are moving faster.

Therefore, the correct answer is

B) the molecules started moving faster.

A solution of zinc nitrate is added to a solution of magnesium sulfate. express your answer as a chemical equation. identify all
alexandr402 [8]

Answer is: no reaction occurs, because all salts are soluble in water.

Balanced chemical reaction:  

Zn(NO₃)₂(aq) + MgSO₄(aq)→ Mg(NO₃)₂(aq) + ZnSO₄(aq).

Ionic reaction:  

Zn²⁺(aq) + 2NO₃⁻(aq) + Mg²⁺(aq) + SO₄²⁻(aq) → Mg²⁺(aq) + 2NO₃⁻(aq) + Zn²⁺ + SO₄²⁻(aq).

This chemical reaction is double displacement reaction - cations and anions of the two reactants switch places and form two new compounds.
