6

Explanation:

You have the unbalanced chemical reaction:

BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF

Knowing that there are 2 atoms of boron in the products, we need to adjust that element putting 2 as coefficient of BF3.

2BF3 + Li2SO3 ⇒ B2(SO3)3 + LiF

Then, we need to balance fluor. There are 6 atoms of F in the reactants, for that reason, we write 6 in the lithium fluoride.

2BF3 + Li2SO3 ⇒ B2(SO3)3 + 6LiF

Finally, sulfur and oxygen have to be adjusted. 3 before lithium sulfite is enough to balance the chemical reaction.

2BF3 + 3Li2SO3 ⇒ B2(SO3)3 + 6LiF

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
