1rst question
..The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
A. Compound that has the highest solubility in pure water is caso4, ksp = 2. 4 x 10-5
More about CASO4:
The inorganic chemical with the formula CaSO4 and its associated hydrates are known as calcium sulphate (sometimes known as calcium sulphate). It serves as a desiccant in the form of -anhydrite (the anhydrous form).
Another hydrate is found naturally as the mineral gypsum, while one is more commonly known as plaster of Paris. It is employed widely in industries. Each form is a white solid that has a low water solubility. Water becomes permanently hard due to calcium sulphate.
CaSo4 is mostly used to produce plaster of Paris and stucco.

Moles pf mgcl2= 2,11/M mgcl2=2,11/95= 0,0222
Molarity=0,0222/1,5=0,0148 M.
I hope this is correct.
Answer:
the hydrogen and the oxygen are the reactants while the H20(water) formed is the product
2Na + Br2 -> 2NaBr
Br is a diatomic element so the 2 is a subscript, not a coefficient.
