27.1 g of SiC are formed by the reaction

Explanation:

The silicium carbide is formed according to the reaction of Carbon and silicium dioxide. We also can produce carbon monoxide at the reaction.

The equation is:

SiO₂ + 3C → SiC + 2CO

According to the stoichiometry we can prodouce 1 mol of silicium carbide, from 3 moles of carbon so we may propose this rule of three:

3 moles of C can produce 1 mol of SiC

Then 2 moles of C, will produce ( 2 . 1) /3 = 0.666 moles of SiC

We conver the moles to mass (mol . molar mass) =

0.666 mol . 40.1 g / 1 mol = 26.7 g

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
