Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.)
note: you are writing the molecular, and not the net ionic equation.
cacl2(aq) + h20(1)

Explanation:

A balanced chemical equation is defined as the one that contains equal number of atoms on bot reactant and product side.

For example,

Number of atoms on reactant side are as follows.

Ca = 1

Cl = 2

H = 2

O = 1

Number of atoms on product side are as follows.

Ca = 1

Cl = 1

H = 3

O = 2

So, in order to balance the above chemical reaction equation we multiply by 2 on reactant side. Hence, the balanced chemical equation is as follows.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

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.
