Answer: CH

Explanation: To calculate the empirical formula of the compound we must first find the number of moles by using the mass of each element.

C= 92.31 g x 1mole C / 12 g C

= 7. 69 moles C

H = 7.69 g H x 1 mole H/ 1 g H

= 7.69 moles H

Next is divide each answer on the lowest number of moles

C = 7.69 / 7.69 = 1

H = 7.69 / 7.69 = 1

So the ratio is 1:1 or CH

Write a balanced equation for the following reaction:
tiny-mole [99]

Answer:

3AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

The coefficients are 3, 1, 3, 1

Explanation:

From the question given above, the following data were:

Silver chloride reacts with sodium phosphate to yield sodium chloride and silver phosphate. This can be written as follow:

AgCl + Na₃PO₄ —> NaCl + Ag₃PO₄

The above equation can be balanced as follow:

AgCl + Na₃PO₄ —> NaCl + Ag₃PO₄

There are 3 atoms of Na on the left side and 1 atom on the right side. It can be balance by putting 3 in front of NaCl as shown below:

AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

There are 3 atoms of Cl on the right side and 1 atom on the left. It can be balance by putting 3 in front of AgCl as shown below:

3AgCl + Na₃PO₄ —> 3NaCl + Ag₃PO₄

Thus, the equation is balanced.

The coefficients are 3, 1, 3, 1
