Answer:

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:

$SiO_2+3C\rightarrow SiC+2CO$

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 = $\frac{3000.00 g}{40 g/mol}= 75 mol$

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

Then 75 moles of SiC will be produce from:

$\frac{1}{1}\times 75 mol=75 mol$ of silicon dioxide.

mass of 75 moles of silicon dioxde:

$75 mol\times 60 g/mol=4500 g=4.5 kg$

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

For the reaction, calculate how many moles of the product form when 0.016mol of O2 completely reacts. . Assume that there is mor

Oksi-84 [34.3K]

The balanced reaction is given as:

2Ca(s)+O2(g)→2CaO(s)

We are given the amount of oxygen gas to be used for the reaction. This will be the starting point of our calculations.

0.016 mol O2 ( 2 mol CaO / 1 mol O2 ) = 0.032 mol CaO

Therefore, for the reaction, the amount of calcium oxide produced is 0.032 moles.
