Carbordum is silicon carbide sic a very hard material used as an abrasive on sand paper and in other applications. it is prepared by the reaction of pur sand sio2 with carbon at high temperature. carbon monoxide co is other product of this reaction. write the balanced equation for the reaction and calculate how much sio2 is required to produce 3.00 kg of sic.

4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.

Explanation:

The balanced equation for the reaction between silicon dioxide and carbon at high temperature is given as:

1 mole silicon dioxide reacts with 3 moles of carbon to give 1 moles of silicon carbide and 2 moles of carbon monoxide.

Mass of SiC = 3.00kg = 3000.00 g

1 kg = 1000 g

Molecular mass of SiC = 40 g/mol

Moles of SiC =

According to reaction, 1 mole of SiC is produced from 1 mole of silicon dioxide.

Then 75 moles of SiC will be produce from:

of silicon dioxide.

mass of 75 moles of silicon dioxde:

4.5 kilograms of silicon dioxide is required to produce 3.00 kg of SiC.
