Which compound is a polar molecule and has a linear geometry

kirill115 [55]

Answer:

Linear molecule is a molecule in which atoms are deployed in a straight line (under 180° angle). Molecules with an linear electron pair geometries have sp hybridization at the central atom. An example of linear electron pair and molecular geometry are carbon dioxide (O=C=O) and beryllium hydride BeH2.

The equation, DF + heat Imported Asset D + F, is an example of an endothermic reaction.

zvonat [6]

The answer is TRUE.

If the Energy is on the left, then the problem is true. If it is on the right then it would be negative, false, and considered as exothermic.

Endothermic reaction = the products are higher in energy than the reactants.
Exothermic reaction = a chemical reaction that releases energy by light or heat.

A mechanism for the decomposition of ozone is (2 O3 â†’ 3 O2). O3 â‡Œ O2 + OO + O3 â†’ O2 + O2What is the molecularity for the f

Gnesinka [82]

Answer:

The correct answer is option c.

Explanation:

Molecularity is defined as number of atoms , ions or molecules that must collide with one another so as to result in a chemical reaction.It is simply the sum of molecules of different reactants as represented in balanced chemical equation.

Reaction taking place in one step are said to be elementary reaction.

Reaction taking place in more than one step are said to be complex reaction.

A mechanism for the decomposition of ozone is given as:

1) $O_3 \rightarrow O_2 + O$

Molecularity for the first elementary reaction is 1. This because single ozone molecule is present.

2) $O + O3\rightarrow O_2 + O_2$

Molecularity for the second elementary reaction is 2. This because single ozone molecule reacts with 1 oxygen atom.
