Which statement is always true about a reversible chemical reaction?
Alecsey [184]
<h2>Answer:</h2>

Option (B):

The products can form reactants, and the reactants can form products.

<h3>Explanation:</h3><h3>Reversible reaction</h3>

A reversible reaction is a reaction where the reactants form products, which react together to give the reactants back.

aA + bB ⇄ cC + dD

A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B.

Other options are wrong because off:

(A) Concentration changes with time equilibrium concentration and higher product concentration is also possible.

(C) They may be constant.

(D) Concentration changes with time equilibrium concentration and higher reactant concentration is also possible.

Perform the following
Dmitry [639]

Answer:

0.5474

Explanation:

3.22 x 0.17

     \/

322 x 17 = 5,474

[] There are four places "after" the decimal in 3.22 and 0.17 combined, meaning we move the decimal to the right four times in our current answer

-> 5,474 becomes 0.5474

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
