Consider the reaction.

2so2(g)+o2(g) < > 2so3(g)

when does the given chemical system reach dynamic equilibrium?
when the forward and reverse reactions stop
when the rate of the forward reaction is higher than the rate of the reverse reaction
when the concentration of the reactants is higher than the concentration of the products
when the rates of the forward and reverse reactions are equal

when the rates of the forward and reverse reactions are equal

Explanation:

Dynamic Equilibrium :  It is a reaction which never stops. But in this type of equilibrium concentration of products and reactants doesn't get alter with the time.The rate of reaction going in a forward direction is equal to the rate of reaction going in a backward direction.

Hence, the given chemical system reach dynamic equilibrium when the rates of the forward and reverse reactions are equal

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
