What happens during a chemical reaction?

Chemistry

Answer: Option (a) is the correct answer.

Explanation:

A chemical reaction is defined as the reaction in which exchange of electrons take place between reactant molecules due to which bonds between reactant molecules are broken down.

This leads to the formation of new compounds known as products which occur due to formation of bonds.

For example, HCl + NaOH \rightarrow NaCl + H_{2}O

Here, bonds between HCl and NaOH are broken down and formation of NaCl and H_{2}O occur due to new bond formation.

Thus, we can conclude that during a chemical reaction the 'reactants' bonds break, and bonds of the products form.

Answer: The reactants’ bonds break, and bonds of the products form.

Explanation:

When a chemical reaction takes place, the bonds are broken and new bonds are formed to make new molecules. Like when 2 water molecules are broken down to form hydrogen and oxygen.

How can bonding determine the properties of a substance?
levacccp [35]

Answer:

Chemical bonds are the electrical forces of attraction that hold atoms or ions together to form molecules. Different types of chemical bonds and their varying intensity are directly responsible for some of the physical properties of minerals such as hardness, melting and boiling points, solubility, and conductivity.

In three different experiments, the following results were obtained for the reaction
faust18 [17]
From the given observations,
You can see that as the concentration is doubled, half-life is halved.

That is,half-life is inversely proportional to concentration

As t( half-life) ~ 1/a^(n-1)

For this case n = 2,second order reaction.

R = k X a^n

Using the above formula you will get the rate and rate constant.

Which Locations are likely to have subatomic particles with the GREATEST mass?
wlad13 [49]

2 and 3, because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4.

Explanation:

The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus.

The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.
