Hey there!
For this we can use the combined gas law:
We are only working with pressure and temperature so we can remove volume.

P₁ = 2 atm
T₁ = 27 C
P₂ = 2.2 atm
Plug these values in:

Solve for T₂.




Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.
Hope this helps!
Answer:
a. 2954g of FeS
b. 1143g of FeS
Explanation:
Based on the reaction:
8 Fe + S₈ → 8 FeS
<em>8 moles of Fe reacts with 1 mole of S₈ to produce 8 moles of FeS</em>
<em />
a. 4.2mol sulfur produce:
4.2mol S₈ × ( 8 mol FeS / 1 mol S₈) = <em>33.6mol FeS</em>. As molar mass of FeS is 87.92g/mol, mass is:
33.6mol FeS × ( 87.92g / 1 mol FeS) = <em>2954g of FeS</em>
<em />
b. 13mol Fe produce:
13mol Fe × ( 8 mol FeS / 8 mol Fe) = <em>13mol FeS</em>. In mass:
13 mol FeS × ( 87.92g / 1 mol FeS) = <em>1143g of FeS</em>
Answer:
Atoms get rearranged and make up different molecules. No atoms are created nor destroyed.
Explanation:
261.162 grams. Use the equation n=M÷Mr.
