The amount of stored chemical energy is what determines the temperature of a substance
Setler79 [48]

Answer:

False

Explanation:

Temperature is the degree of hotness or coldness of a body. Temperature is as a result of how much heat a body has. Heat is a form of energy called thermal energy. Heat can be transferred from one body to another as a result of differences in temperature between two bodies.

Chemical energy does not determine the temperature of a body. It is the amount of heat it contains.

How many moles of electrons is required to deposit 5.6g of iron from a solution of iron (2) tetraoxosulphate(6)
yuradex [85]

Answer:

0.20 mol

Explanation:

Let's consider the reduction of iron from an aqueous solution of iron (II).

Fe²⁺ + 2 e⁻ ⇒ Fe

The molar mass of Fe is 55.85 g/mol. The moles corresponding to 5.6 g of Fe are:

5.6 g × 1 mol/55.85 g = 0.10 mol

2 moles of electrons are required to deposit 1 mole of Fe. The moles of electrons required to deposit 0.10 moles of Fe are

0.10 mol Fe × 2 mol e⁻/1 mol Fe = 0.20 mol e⁻
