Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.

<h3>What is  Lewis dot structure?</h3>

A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.

Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

How many co2 molecules would be formed from the reaction mixture that produces the greatest amount of products?
bezimeni [28]
<h2>Answer : 2 molecules of CO_{2} will be formed.</h2><h3>Explanation :</h3>

Considering the reaction as

2CH_{3}OH_{(g)}+3O_{2}_{(g} -----> 2CO_{2}_{(g)}+4 H_{2}O_{(g)}

Here, 2 molecules of methyl-alcohol combines with 3 molecules of oxygen to give 2 molecules of CO_{2} and 4 molecules of H_{2}O.

If 1 molecule of methanol is used then only one carbon dioxide molecule will be produced. But as per the given reaction two moles of methanol will produce 2 moles of carbon dioxide molecules.

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]

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

<u>Explanation:</u>

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.
