Complete and balance the following acid-base equations:
(a)a solution of hclo4 is added to the solution of lioh.
(b) aqueous h2so4 reacts with naoh.
(c)ba(oh)22 reacts with hf gas.

a)

b)

c)

Explanation:

a)

when is added to LiOH, lithium chlorate and water is formed.

Balancing of above reaction,

It can be seen that all the atoms in both the sides are balanced. so it is a balanced reaction.

(b) When aqueous is added to NaOH, and is formed. It is a neutrilization reaction.

Balancing of above reaction,

First balance all the atoms except O and H

S atom is already balanced in either side

No. of Na atom in left hand side = 1

No. of Na atom in right hand side = 2

So multiply NaOH by 2, now the reaction becomes:

No. of O atoms in left hand side = 6

No. of O atoms in right hand side = 5

So multiply H2O by 2, now the reaction becomes:

Now, it can been seen that all the atoms are balanced.

c) When reacts with HF, baroum fluoride and water is formed.

Balancing of above reaction,

Barium atoms are already balanced on either side.

No. of F atoms on left hand side = 1

No. of F atoms on right hand side = 2

So, multiply HF by 2, now reaction becomes

In order to balance H and O on either side, multiply H2O by 2.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
