Answer:
Chromium
Explanation:
Cr has 24 atomic number and mass number 52
Since water has a density of about 1g/mL, and we are assuming HCl and NaOH are mostly water, the total mass of the 2 solutions is 100 g.
Due to the conservation of mass, the mass of product must equal the total mass of reactant, therefore the final mass must also be 100 g.
Answer:
The answer is B) The law of conservation of energy.
Explanation:
This is the answer because energy cannot be created or be destroyed in a isolated system. The second law as well states that the entropy of any isolated system always increases.
