statement 1,mass is conserved durning the reaction. statement 2 sum of mass and energy is conserved durning the reaction. which statement is true for both nuclear reaction and chemical reaction

Explanation:

None of the statement is true for both chemical and nuclear reactions. In chemical reactions, mass is always conserved and the type of atoms are also conserved.

14g of A would come out

Explanation:

The solubility of A at 60°C is 11g/100mL. In 200mL, solubility is:

22g/200mL. That means, the 20g of A will be dissolved completely at 60°C.

Then, at 25°C, the solubility of A is 6g/200g. That means the amount of A that precipitates during the temperature decreasing is:

20g-6g =

14g of A would come out
