Answer:

The correct answer is NaCl and AgNO.

Explanation:

A reactant is a substance or compound that is added to a system to cause a chemical reaction.

Therefore, a reactant is any substance that interacts with another in a chemical reaction that results in other substances of different properties, characteristics, and conformation called chemical reaction products.

Have a nice day!

what is the molecular formula of benzoyl peroxide (c7h5o2) of the molecular mass is 0.242 kg/mol?(show work please)

AfilCa [17]

Answer : The molecular formula of benzoyl peroxide is $C_{14}H_{10}O_4$

Explanation :

Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.

Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

$n=\frac{\text{Molecular mass}}{\text{Empirical mass}}$

As we are given that the molar mass of compound is, 0.242 kg/mol.

Molecular mass = 0.242 kg/mol = 242 g/mol (1 kg = 1000 g)

The empirical mass of $C_7H_5O_2$ = 7(12) + 5(1) + 2(16) = 121 g/eq

$n=\frac{\text{Molecular mass}}{\text{Empirical mass}}$

$n=\frac{242}{121}$

$n=2$

Molecular formula = $(C_7H_5O_2)_n$ = $(C_7H_5O_2)_2$ = $C_{14}H_{10}O_4$

Thus, the molecular formula of benzoyl peroxide is $C_{14}H_{10}O_4$

A rectangular block of copper has a mass of 143.584 g and measures 5.05 cm by 2.55 cm by 1.25 cm. Find the density of the copper

Luba_88 [7]

Density=mass/volume
Volume= 5.05 x 2.55 x 1.25 = 16.096875 cm^3

Density= 143.584/16.096875
= 8.919992235 g/cm^3
