It is converted to heat/thermal energy.
Hello!
To know how many grams of
Ammonium Chloride ( a solid) you'll need to make 1.50 L of a 0,01 M solution you'll need to use the definition of molar concentration (M=mol/L) in the following way:

So, you'll need to dissolve
0,8023 g of Ammonium Chloride in 1,5 L of water to make this solution.
Have a nice day!
The amount of heat required is calculated using the below formula
Q(heat) =M(mass) xC(specific heat capacity)x delta T (change in temperature)
change in the temperature in kelvin=(35+273)- (25 +2730= 10K
c= 2.48 j/g/k
mass= 54.0 g
Q= 54.0 g x 2.48 j/g/k x 10k = 1339.2 joules is required
Copper oxide
element x is oxygen location,group 16
