If 0.10 mol of ammonium chloride (NH4Cl) is dissolved in water producing 2.27 x 102
g solution, the water temperature decreases from 25.0°C to 19.0°C. Given
that the specific heat of the resulting solution is 1.00 cal/g.°C), calculate the
energy absorbed by the system?
A. 4.18)
B. 5.9 x 10^3 cal
C. 1.4 x 10^3 cal
D. 1.00 cal
E. 0.10 cal

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

not clear

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
