Answer:

Chemical bond can be define as a force holding atoms firmly together to a form molecules.

Explanation:

Chemical bond is a strong attraction between atoms, molecules or ions that enhance the formation of chemical compounds. The bonds may be due from the electrostatic force of attraction between opposite charged ions or through the sharing of electrons.

Types of chemical bond

There are four types of chemical bonds

- covalent bond

- polar bond

- ionic bond

- hydrogen bond

Ionic bond involves the transfer of an electron which involves one atom receiving and the other giving out

Covalent bond involves the sharing of electrons between two atoms

Polar bonds involves two atoms connected by covalent bonds which may exert different attractions for the electrons in the bond resulting into unevenly charges distribution

Hydrogen bond: this is found mostly in water H2O. They are polarized

HELP PLEASE
Tatiana [17]

Answer:

Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant.

Explanation:

Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.

In a well-constructed response explain the differences and similarities between Natural Selection and Selective Breeding
lakkis [162]
Natural selection and selective breeding can cause both animal and plant changes. The distinction between the two is that natural selection occurs without human intervention, while selective breeding occurs only when humans interfere. As a result, selective breeding is also known as artificial selection.
