The true statement is (A) energy is absorbed during the reaction
For the products to have more energy, they must absorb it from the surrounding.
Answer:
(12×4)+(1×2)=50
Explanation:
mass of Carbon is 12....mass of hydrogen is 1
The reaction of HCl and NaOH is HCl + NaOH = NaCl + H2O. So the mole number of HCl and NaOH is equal. So the volume of HCl =0.01*0.1/0.02=0.05 L =50 ml. So the answer is D).
