The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.

<h3>What is the equilibrium constant?</h3>

The equilibrium constant is a figure that tells us the extent to which the reactants have been converted to products in a reaction.

Now we have the reaction; PCl3(g) + Cl2(g) ⇄ PCl5(g) hence we can write;

Q = [PCl5]/[PCl3] [Cl2]

Q = 0.39/0.21 * 0.41

Q = 4.5

The reaction is not at equilibrium because Q >P hence the reaction moves towards the left hand side.

. 20 mL ethanol in 60 mL solution
goldenfox [79]

The solution is the mixture of the solute into the solvent particles. In 60 mL solution, 59.8 mL of solvent is added.

<h3>What are solute and solvent?</h3>

Solute and solvent are the components of a solution. They react and mix together to produce a homogenous mixture. The solute is a substance that is added to the solvent.

Solvents are substances that dissolve the added solute in them to make a homogenous solution.

Given,

Volume of Solute = 0.20 mL

Volume of Solution = 60 mL

The volume of solvent is calculated as:

Volume of solvent = Volume of solution - Volume of solute

= 60- 0.20

= 59.8 mL.

Therefore, 59.8 mL of solvent is present in 60 mL of solution.

Answer:

The correct answer is "A consumer is obtaining carbon by eating carbon-based molecules stored in a producer".

Explanation:

The animal is consuming the carbon present in the molecules stored in the grass. Plants process the carbon present in the soil along with other minerals. The animal, when it feeds on these plants, is consuming the carbon they obtained from the soil. Grasslands are defined largely by their use for grazing, which includes between 10 and 30 percent of soil carbon worldwide.

Have a nice day!
