First, make sure to balance your equation.
3H2(g) + N2(g) ⇄ 2NH3(g)
Now, you can write your Kc expression. Remember that Kc is products over reactants, and the exponent for each product or reactant is based on its coefficient.
Kc = [NH3]^2 / [H2]^3[N2]
<u>Answer:</u> The volume of given mas of tin block at STP is 
<u>Explanation:</u>
To calculate volume of of the substance, we use the equation:
We are given:
Mass of tin = 95.04 g
Density of tin = 
Putting values in above equation, we get:
Hence, the volume of given mas of tin block at STP is

<span>Chemical reaction is:
Zn+PbS<span>O4</span>→ZnS<span>O4</span>+P<span>b
</span></span>From the balanced equation 2 moles of Zn make 2 moles of ZnSO4
<span>You have 0.534 moles of zinc so you make 0.534 moles of ZnSO4. </span>
Molar mass of ZnSO4 = 161 g/mol
mass = no of moles * molar mass
mass = 0.534 * 161
mass = 85.974 g
