High-Strength Ceramic Materials Production Calculation

How is silicon carbide produced from the reaction of silicon dioxide and coke? The production of silicon carbide involves the combination of silicon dioxide and coke to form the compound SiC. This process results in the creation of high-strength ceramic materials. To determine the mass of silicon carbide produced from the reaction of 352 g of silicon dioxide, we can follow these steps:

Chemical Equation

The chemical equation for the reaction of silicon dioxide and coke to produce silicon carbide is:

SiO₂ + 3C → SiC + 2CO

Calculation

Given data:

Mass of SiO₂ react = 352 g

Mass of SiC formed = ?

Solution:

Number of moles of SiO₂:

Number of moles = mass / molar mass

Number of moles = 352 g / 60.08 g/mol

Number of moles = 5.86 mol

Now, we will compare the moles of SiO₂ with SiC from the balanced chemical equation:

SiO₂ : SiC

1 : 1

5.86 : 5.86

Mass of SiC:

Mass = number of moles × molar mass

Mass = 5.86 mol × 40.11 g

Mass = 235 g

Therefore, the mass of silicon carbide produced from the reaction of 352 g of silicon dioxide is 235 g.
