The true statements are B, C, and D
-first ( A ) the concentrations of reactants and products are equal is false, As the concentrations of reactants and products may be different from each other.
- But (B) the concentrations of reactants and product remains constant is true, as the equilibrium remains when there is no change in the concentration of the reactants and products.
-(c) reactants are being converted to products (and vise verse) is true also, as there are reactions still happened at a constant rate so it looks like nothing is happening.
Answer:
Explanation:
Blood is an essential part of the circulatory system in the human body. The main function of blood is that it helps to transport materials to different parts of the body where they are need.

Not sure about the first one.
Wind farms can be set up anywhere.
To provide electricity to homes.
Recycling aluminum cans.
I think the answer is peridotite
The keyword here is gas condenses to a liquid, which mean we're talking about condensation process
The enthalpy energy in condensation process is negative because it releases energy
The entropy in general will also decreases .
Temperature affect this change because it will create free energy if added with this result
hope this helps
