Consider the following balanced equation. SiO 2 (s)+3C(s)SiC(s)+2CO(g) Complete

Question

Consider the following balanced equation.
SiO 2 (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 formed. If the number of moles of a product is provided, fill in the required amount of each reactant to make that amount of product, as well as the amount of the other product that is made.

Complete each row.

molSiO 2 molC molSiC molCO _____ 9 _____ _____ 3 _____ _____ _____ _____ _____ _____ 30 _____ 7.5 _____ _____ 2.4 _____ _____ _____

Explanation / Answer

Looking at the reaction,

1 mole of SiO2 reacts with 3 moles of C to form 1 mole of SiC and 2 moles of CO

So the ratios are : SiO2 : C : SiC : CO = 1 : 3 : 1 : 2

Completed Table below,

molSiO2    molC    molSiC    molCO

    3               9            3            6

    3               9            3            6

   15             45          15          30

   2.5            7.5         2.5        5.0   

   2.4            7.2         2.4        4.8
