This is a chemical reaction for the decomposition of carbonic acid into water and carbon dioxide.
H2CO3→H2O + CO2
How does the reaction support the Law of Conversation Mass?
a). The mass of carbon atoms is reduced during the reaction
b). The mass of the atoms in the reactant equals the mass of the atoms in the products
c). The mass of hydrogen atoms is the only thing that remains the same before and after the reaction
Answer:
H2CO3 → CO2 + H2O decomposition in the presence of H2O, HCOOH, CH3COOH, H2SO4 and HO2 radical: instability of the gas-phase H2CO3 molecule in the troposphere and lower stratosphere†
Explanation:have fun
The correct statement given the data is:
The mass of the atoms in the reactant equals the mass of the atoms in the products (Option B)
What is a chemical equation ?Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Considering the equation given from the question
H₂CO₃ —> H₂O + CO₂
Reactant
H = 2 atomsC = 1 atomO = 3 atomsProduct
H = 2 atomsC = 1 atomO = 3 atomsFrom the description of the reactant and product, w can see that the atoms in both reactant and product are the same. Hence the equation support the law of conservation of mass
