Write the reaction as a CO2 + b H2O → c C6H12O6 + d O2 where a, b, c, and d are meant to be integers adjusted so that the number of each kind of atoms balance on each side. For this reaction, we have three kinds of atoms that must balance: carbon (C), hydrogen (H), and oxygen (O). Write three equations for a, b, c, and d that, if satisfied, will guarantee that the number of atoms of each kind are the same on each side of the reaction.

a = 6, b = 6, c = 1 and d = 6

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Explanation:

a CO₂ + b H₂O → c C₆H₁₂O₆ + d O₂

In the balance for Carbon (C)

a = 6c

In the balance for Oxygen (O)

2a + b = 6c + 2d

In the balance for Hydrogen (H)

2b = 12 c

b = 6c

To solve, we bring the equations together

a = 6c (eqn 1)

2a + b = 6c + 2d (eqn 2)

b = 6c (eqn 3)

Substituting for b and a in (eqn 2)

2a + b = 6c + 2d

2(6c) + 6c = 6c + 2d

12c + 6c = 6c + 2d

2d = 12c

d = 6c

Let c = 1

a = 6c = 6

b = 6c = 6

d = 6c = 6

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

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.  

i'm pretty sure its b i might be wrong though!
