Which statement is correct regarding the reaction ?

Chemistry
1 answer:
larisa86 [58]2 years ago
5 0

The true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

<h3>What is true about the given reaction?</h3>

The given reaction shows a reaction between A and B to form CD

The reaction is a reversible reaction.

A reversible reaction is a reaction which can proceed in either of two ways where the reactants can react to form the product and also the products an break down to form the reactants.

In the reaction given, as the concentration of A and b decreases, the concentration of CD increases and vice versa.

At equilibrium, the rate of formation of CD is equal to the the rate of decomposition of CD.

Therefore, the true statement is that after reaching equilibrium, the rate of forming products and reactants is the same.

In conclusion, a reaction at equilibrium has the forward and backward reactions occurring at the sane rate.

All magnetic minerals will have the element iron in the chemical composition true or false
Margaret [11]

The statement is true. If a mineral lacks the presence of iron in it then it will be generally dimagnetic.  It means non iron minerals do not show magnetic property in general. There are some minerals like serpentine do show some magnetic susceptibility, however this is negligible as compared to iron minerals hence the ores with no magnetic are generally diamagnetic.

What effect will increased pressure have on 4A (g) + 5B (g) ---&gt; 2C (g) + 7D (g) 
Pie

Answer:

  • <em><u>Option a. no change</u></em>

Explanation:

The question makes sense only if the equation is an equilibrium reaction:

  • <em>4A (g) + 5B (g) ⇄ 2C (g) + 7D (g) </em>

This is, A and B react to produce C and D, forward reaction; and C and D react to form A and B, reverse reaction.

Then, you can study the effect of increased pressure using LeChatelier's principle.

To counteract the disturbing effect produced by increased pressure on the equilibrium, the system will react shifting the toward to the side where the pressure could be decreased.

That would be toward the side that has less gas molecules.

Since both sides have 9 molecules (4 + 5 = 2 + 7 = 9), the equilibrium concetrations will not change.

That is represented by the first choice: no change.
