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)

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

Product

From 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

Hammer orchids are plants with flowers that are highly modified to resemble a female thynnid wasp (i.e., a wasp of the Thynnidae family) and can only be pollinated by thynnid wasps. Female thynnid wasps cannot fly, but males can. When the female is prepared to mate, she will climb up a tall plant or a blade of grass and wait for a male to appear. Males will pick up the female from her perch and mate with her in flight.


Given this information, in three to five sentences, describe these details:

one other feature of the hammer orchid that could attract its pollinator
how the orchid’s flower adaptation could lead to pollination
why you believe a plant would have more reproductive success with either a specialized pollinator or multiple pollinators
