Answer:

It breaks down into multiple elements

Explanation:

A decomposition reaction is a type of chemical reaction in witch a single compound breaks down into two or more elements or new compounds. These reactions often involve an energy source such as heat, light, or electricity that breaks apart the bonds of compound

A decomposition reaction is when a compound breaks down into elements or smaller compounds.

For example, 2 moles hydrogen peroxide, H2O2, could decompose into 2 moles of water and one mole of oxygen.

2 H2O2 = 2 H2O + O2

One method for preparing pure iron from Fe2O3 is by reaction with carbon monoxide.Fe2O3(s)+CO(g)→Fe(s)+CO2(g) How many moles of
larisa [96]

Answer:

The 2292 moles of CO are needed to react completely with 122 Kg of Fe₂O₃.

Explanation:

Given data:

Mass of Fe₂O₃ = 122 Kg ( 122×1000 =  122000 g)

Moles of CO = ?

Solution:

Chemical equation:

Fe₂O₃ + 3CO  → 2Fe + 3CO₂

Number of moles of  Fe₂O₃:

Number of moles = mass/ molar mass

Number of moles = 122000 g /159.69 g/mol

Number of moles = 764 mol

Now we will compare the moles of Fe₂O₃ with CO.

                               Fe₂O₃            :            CO  

                                  1                  :             3

                               764                :             3×764  =2292 mol

The 2292 moles of CO are needed to react completely with 122 Kg of Fe₂O₃.

frutty [35]

<u>Answer:</u> The structure of the geometrical isomers are attached below.

<u>Explanation:</u>

Cis- and Trans- isomers are the geometrical isomers which have same chemical formula but different structural formula

According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as cis-form and if the highest priority groups are on opposite side, it is known as trans-form.

We are given a chemical compound, which is 2-pentene.

In this the highest priority groups are methyl and ethyl groups.

When the groups are on the same side, it forms cis-form and when the groups are on the opposite side, it forms trans-form

The structure of the geometrical isomers are attached below.
