When C2H5Cl(g) is burned in oxygen, chlorine gas is produced in addition to carbon dioxide and water vapor. 5145 kJ of heat are

Arisa [49]

Answer: The chemical equation is written below.

Explanation:

Combustion reaction is defined as the chemical reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide gas and water molecule.

$\text{hydrocarbon}+O_2\rightarrow CO_2+H_2O$

The chemical equation for the combustion of ethyl chloride follows:

$4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O$

We are given:

When 4 moles of ethyl chloride is burnt, 5145 kJ of heat is released.

For an endothermic reaction, heat is getting absorbed during a chemical reaction and is written on the reactant side.

$A+\text{heat}\rightleftharpoons B$

For an exothermic reaction, heat is getting released during a chemical reaction and is written on the product side

$A\rightleftharpoons B+\text{heat}$

So, the chemical equation follows:

$4C_2H_5Cl+13O_2\rightarrow 2Cl_2+8CO_2+10H_2O+5145kJ$

Hence, the chemical equation is written above.

What is the molecular geometry of the underlined carbon atom in the following compound: HC-C-CH3?

Tom [10]

Answer:

linear

Explanation:

If we look at the compound, we will understand that the underlined carbon is in sp hybridization. Recall that sp hybridization leads to a C-C bond angle of about 180°. When two chemical species are at a bond angle if 180°, then the both bonding groups are found to be on a straight line.

Hence, for any carbon in a triply bonded state or indeed any carbon atom that is in an sp will exhibit a linear geometry according to the Valence Shell Electron Pair repulsion Theory since there are two electron pairs present.
