Arrange the following in order of increasing bond strength of the carbon oxygen bond:
Brilliant_brown [7]

Answer:

The correct option is: Carbonate ion < Carbon dioxide < Carbon monoxide

Explanation:

Bond energy is defined as the average energy needed to break a chemical covalent bond and signifies the strength of chemical covalent bond.

The bond strength of a covalent bond depends upon the <u>bond length and the bond order.</u>

Carbon monoxide molecule (CO) has two covalent bond and one dative bond. Bond order 2.6

Carbon dioxide (CO₂) has two carbon-oxygen (C-O) double bonds of equal length. Bond order 2.0

Carbonate ion (CO₃²⁻) has three C-O partial double bonds. Bond order 1.5

Also, the bond length is <u>inversely proportional to the bond order and bond strength.</u>

Therefore, <u>order of C-O bond length:</u> Carbon monoxide<Carbon dioxide<Carbonate ion

<u>Order of C-O bond order</u>: Carbonate ion<Carbon dioxide<Carbon monoxide

<u>Order of C-O bond strength or energy</u><u>: Carbonate ion<Carbon dioxide<Carbon monoxide</u>

What effect does reusing or recycling municipal waste have on environmental resources? Group of answer choices increased use of
Effectus [21]

Answer:

preservation of raw materials

Explanation:

Reusing and recycling is the process by which the used products are used again or recycled in different form to use it again. Excessive use of the raw materials can lead to their extinction. Recycling the materials helps in decreasing the pollution in the environment. It also helps in reduction in the emission of the harmful gases. When municipal wastes are reused or recycled, the raw materials are preserved. These are the process involved in sustainable use of resources.

How many grams of MgCl2 (molar mass = 95.20 g/mol) will be formed from 25.6 mL of a 0.100 M HCL solution reacting with excess ma
lorasvet [3.4K]
The balanced equation for the above reaction is as follows;
Mg + 2HCl ---> MgCl₂ + H₂
stoichiometry of HCl to MgCl₂ is 2:1
we have been told that Mg is in excess therefore HCl is the limiting reactant 
number of HCl moles reacted - 0.100 mol/L x 0.0256 L = 0.00256 mol
according to molar ratio, number of MgCl₂ moles formed - 0.00256/2 
Therefore number of MgCl₂ moles formed - 0.00128 mol
mass of MgCl formed - 0.00128 mol x 95.20 g/mol = 0.122 g
