<h3><u>Answer;</u></h3>
<u> = 1319.45 Joules </u>
<h3><u>Explanation;</u></h3>
Kinetic energy is the energy possessed by a body in motion;
It is given by the formula; 1/2mv², where m is the mass of the body and v is the velocity.
mass = 89.5 kg and v =5.43 m/s
Therefore;
Kinetic energy = 1/2 × 89.5 × 5.43 ²
<u> = 1319.45 Joules </u>
Answer:
The formula of the compound formed by Iron (ii) ions and chromate ions is FeCrO₄
Explanation:
Iron (ii) ions, Fe²⁺ have a positive charge of +2. Chromate ions, CrO₄²⁻, on the other hand have a positive charge of -2. When iron (ii) ions and chromate ions combine two form a compound, each ion will contribute a mole of ion towards the formation of the compound. This is in line with the idea that a compound carries no charge. The positive charge (+2) of the iron (ii) ions are balanced by the negative charge of the chromate ions as shown mathematically as follows;
+2 + (-2) = 0; i.e. Fe²⁺ + CrO₄²⁻ = FeCrO₄
Therefore, the formula of the compound formed by Iron (ii) ions and chromate ions is FeCrO₄
