Which statement describes a change that occurs during a chemical reaction? OA. The atoms in a substance start to move faster until they are no longer touching each other.
OB.
Atoms in the original substances are arranged in a different way to make new substances
OC!
The atoms in a substance change their properties so they can become a new substance.
OD.
Atoms in the original substances are changed into different atoms to make new substances,

Answer - B Atoms in the original substances are arranged in a different way to make new substances

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
