We can solve this problem using Raoults law. The formula for Raoults law is:

P_a = X_a * P

where,

P_a = the partial pressure of substance A

X_a = the mole fraction of substance A

P = total pressure

 

Therefore calculating for P:

P = P_a / X_a

P = 0.580 atm / 0.35

<span>P = 1.657 atm</span>

What do genotype will appear in boxes 2 and 3?
VMariaS [17]
Tt is the genotype that will appear in boxes two and three.

If you look at the column and row that intersect to form boxes two and three, you will see that they are T and t. That is the best way I can describe it, sorry if it’s confusing.

The effect of a catalyst on an equilibrium is to ________. Select one: a. increase the rate of the forward reaction only b. slow
Georgia [21]

Answer:

E

Explanation:

A catalyst is a substance which alters the rate of a chemical reaction. We check for the correctness of each of the options as follows:

A. Is wrong.

A catalyst can increase the rate of the forward and backward reaction

B. Is wrong

A catalyst does not slow the reverse reaction only. This particular case is the case of a negative catalyst

C is wrong

A catalyst has no effect on the equilibrium nor the equilibrium constant

D is wrong

Catalyst has no effect on equilibrium value

E is correct

Although Catalysts has no effect on equilibrium or its constant value, it can increase the the rate at which equilibrium is achieved by speeding up the reaction through bringing down the activation energy

Consider four beakers labeled a, b, c, and d, each containing an aqueous solution and a solid piece of metal. identity the beake
puteri [66]
To identify in what beakers will a reaction occur, we need to know what aqueous solution is in the four beakers. Then, we also need to know what metals are placed inside those beakers. Now, we can analyze which metals might or will react to the solution in the beakers.
