Answer:
A. sulfur dioxide
Explanation:
The volcanoes are able to influence the global climate both on the short term and on the long term. The end result can be either cooling off of the climate, or warming up of it, depending on what type of gasses are the volcanoes going to release in the atmosphere, as well as how much of them. The sulfur dioxide is a gas that is released by the volcanoes that causes cooling off of the climate. This gas is going through conversion and becomes sulfuric acid, and it is able to restrict the amount of sunlight reaching the surface of the Earth, as well as increasing the reflective properties of the atmosphere, resulting in a few years of significant cooling of the climate.
Answer:
The concentration of the products and reactants is constant.
Explanation:
Once the reversible reaction that proceeds forward and backward simultaneously has reached it's state of chemical equlibrium, the concentration of products and reactants become constant.
This means that the rate at which the reactants react to form products becomes equal to the rate at which products react to form the reactants again. At this point there will be no further change in the concentration of reactants and products with time. In chemical equilibrium the concentration of a reactant or a product is expressed in moles per cubic decimeter ( mol / dm^3.
