Answer:
Precentage error = 7.23%
Explanation:
The precentage error formula is the useful method for determining precision of your experimental result
It can be calculated using :


So we get percentage error = 7.23%
Precision means how close the experimental value to the true value or theoretical value
If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment
If the percentage error is zero it means the experiment is perfectly done without inaccuracy

increase
Explanation:
Reactions that are initiated by light are called photochemical reactions. The brighter the light, the faster the reaction.
Potassium carbonate reacts with barium chloride to precipitate insoluble barium salts that is barium carbonate, when the solutions are mixed together you'll see white precipitate that is barium carbonate and potassium is dissolve in the solution to form potassium chloride.
