The chemical formula for this compound : Cu₂SO₄-Copper(I) sulfate

<h3>Further explanation</h3>

Given

2 atoms of Copper, 1 atom of Sulfur and 4 atoms of Oxygen.

Required

The chemical formula

Solution

The number of atoms forming a compound is usually indicated from the subscript in the formula

From the problem it can be seen that the compound has:

2 atoms of Cu, 1 atom of S, and 4 atoms of O

So the formula:

<em>Cu₂SO₄</em>

A diver exhales a bubble with a volume of 250 mL at a pressure of 2.4 atm and a temperature of 15 °C. What is the volume of the
alexdok [17]

Answer : The volume of the bubble is, 625 mL

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 2.4 atm

P_2 = final pressure of gas = 1.0 atm

V_1 = initial volume of gas = 250 mL

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 15^oC=273+15=288K

T_2 = final temperature of gas = 27^oC=273+27=300K

Now put all the given values in the above equation, we get:

\frac{2.4atm\times 250mL}{288K}=\frac{1.0atm\times V_2}{300K}

V_2=625mL

Therefore, the volume of the bubble is, 625 mL
