What is the precipitate that will form from the reaction of barium chloride dihydrate with sodium sulfate decahydrate?

The formation of an insoluble salt on mixing of two solutions which contains soluble salts is refer to a precipitation reaction. The insoluble salt formed in the reaction is said to be a precipitate and can be separated by filtration or any other separation method.

The formula for barium chloride dihydrate is .

The formula for sodium sulfate decahydrate is .

The hydrates on the above compounds represents that they are in the aqueous phase. So, the reaction is:

The above equation is not balanced as the number of atoms of elements on the reactant side is not equal to the number of atoms of elements on the product side. So, in order to balance the reaction, on the reactant side is multiplied by 2. Thus, the balanced chemical equation is:

Hence, the precipitate that will form from the reaction of barium chloride dihydrate with sodium sulfate decahydrate is barium sulfate, .

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 : )
