If you would like to complete your goals, keep this in mind! shown below some question and answer examples that you would possibly utilize to enriches your knowledge and gain insight that will guide you to maintain your school studies.
Question:
Which of the following reactions is balanced?A.CaCl2 + 2H2CO3 = CaCO3 + HCI
B.2C2Cl2 + H2CO3 +CaCO3 + HCl
C.CaCl2 + H2CO3 + 2CaCO3 + HCI
D.CaCl2 + H2CO3 + CaCO3 + 2HCI
Answer:
The chemical equation occurs whenever the number of atoms included in the side of the reaction equals the atomic mass involved inside the product’s side. Following are calculations to the balanced reaction:
Sides of the reactant:
are present on the reactant’s side.
Calculating the product side:
- Since the number of moles of element atoms/ions on both the reactants and the sides of the product of the given interaction is the same.
