Question

Consider the balanced equation:

SiO2(s)+3C(s)---> SiC(s)+2CO(g)

Complete the following table showing the appropriate number of moles of reactants and products. If the number of moles of a reactant is provided, fill in the required amount of the other reactant, as well as the moles of each product that forms. If the number of moles of a product is provided, fill in the required amount of each reactant to make the amount of product, as well as the amount of the other product that forms.

Mol SiO2 Mol C Mol SiC Mol CO 3 9 12 3.3 2.45

Explanation / Answer

1 mole of SiO2 react with 3 mol C to give 1 mol SiC and 2 mol CO. the table can be completed keeping this in mind.

Mol SiO2 Mol C Mol SiC Mol CO 3 3x3= 9 1x3= 3 2x3=6 (1/3)x9=3 9 1(1/3)x9=3 (2/3)x9=6 (1/2)x12=6 (3/2)x12=18 (1/2)x12=6 12 3.3 3x3.3=9.9 1x3.3=3.3 2x3.3=6.6 (1/3)x2.45=0.82 2.45 (1/3)x2.45=0.82 (2/3)x2.45=1.64
