If 10g of KCIO3 dissolve in 100g of water at 30 degrees C, what type of solution is it?

It's either 3 or that ,,but if not than choose 4

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.

Coal i believe hope this
