The value of equilibrium constant is equal to the quotient of the products raised to its stoichiometric coefficient over the reaction's reactants raised to its respective stoichiometric coeff. The equation is Kc=[SO2][Cl2]/[SO2Cl2]= [1.3*10^-2][1.3*10^-2]/[2.2*10^-2-<span>1.3*10^-2]=0.0188. The final answer is Kc=0.0188.</span>

The dicotyledons, also known as dicots, are one of the two groups into which all the flowering plants or angiosperms were formerly divided. The name refers to one of the typical characteristics of the group, namely that the seed has two embryonic leaves or cotyledons.
The remaining 3 % are nanomaterials made from e.g. aluminium oxide, barium titanate, titanium dioxide, cerium oxide and zinc oxide. Carbon nanotubes, graphene and fullerenes have annual production amounts in the hundred tonnes range. Nanosilver is estimated to be produced in about 20 tonnes per year.

Explanation:
The equation of the reaction is given as;
12C + 16 H2 --> 4 C3H8
a. Simplify the equation;
The coefficients are 12, 16 and 4.
4 is a common factor, so divide all through by 4.
12/4 = 3, 16/4 = 4, 4/4 = 1
The equation is given as;
3 C + 4 H2 --> C3H8
b. If 21 moles of C3H8 are formed, how many moles of C was needed.
From the reaction;
3 mol C atoms reacts to form 1 mol of C3H8
x mol would react to form 21 moles of C3H8
3 = 1
x = 21
x = 21 * 3
x = 63 moles
