Answer:
Cu + Cl2 → CuCl
To happen the reaction, copper metal is heated.
1 mole of any gas under STP has volume 22.4 L.
Molar mass M(H2S) = 2M(H) + M(S)= 2*1.0 +32.1=34.1 g/mol
15g * 1mol/34.1g= 0.440 mol
0.440 mol*1L/22.4L= 9.85 L
<span> The volume of 15.0 grams of H2S at STP is 9.85 L.</span>
<span>No need to balance the equation... it's already balanced
MgBr2 + Cl2 -> MgCl2 + Br2 </span>
