2 answers:

8 0

Answer: Humans are moving more carbon into the atmosphere from other parts of the Earth system. More carbon is moving to the atmosphere when fossil fuels, like coal and oil, are burned. More carbon is moving to the atmosphere as humans get rid of forests by burning the trees.

What is the total number of electron pairs shared between the carbon atom and one of the oxygen atoms in a carbon dioxide molecu

TEA [102]

The answer is 2 pairs. The carbon atom has 4 electrons and oxygen atom has 6 electrons. The purpose of shared electron is to get 8 electrons at the outer layer. So the carbon atom needs to share 4 electrons which is 2 pairs with oxygen to be stable.

Silicon reacts with carbon dioxide to form silicon carbide sic and silicon dioxide

andrew-mc [135]

The question is incomplete, here is the complete question:

Silicon reacts with carbon dioxide to form silicon carbide and silicon dioxide. Write the balanced chemical equation.

<u>Answer:</u> The balanced chemical equation is written below.

<u>Explanation:</u>

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the reaction of silicon and carbon dioxide follows:

$2Si+CO_2\rightarrow SiC+SiO_2$

By Stoichiometry of the reaction:

2 moles of silicon reacts with 1 mole of carbon dioxide gas to produce 1 mole of silicon carbide and 1 mole of silicon dioxide

Hence, the balanced chemical equation is written above.
