Answer:

Explanation:

The algebraic sum of all the oxidation numbers of all atoms in a neutral compound is zero.

In order to know the formula of the negative Sulfur ion in pyrite, we must determine its oxidation state.

Let us make the make the oxidation number of sulfur = x

Therefore, FeS₂:

                      +2 +2x = 0

                      +2 = -2x

                       x = -1

The formula of the negative ion is S⁻

Answer : The pressure it exert under these new conditions will be, 87 atm

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 = 19 atm

P_2 = final pressure of gas = ?

V_1 = initial volume of gas = 100 L

V_2 = final volume of gas = 20 L

T_1 = initial temperature of gas = 25^oC=273+25=298K

T_2 = final temperature of gas = 0^oC=273+0=273K

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

\frac{19atm\times 100L}{298K}=\frac{P_2\times 20L}{273K}

P_2=87atm

Therefore, the pressure it exert under these new conditions will be, 87 atm
