Answer: Option (b) is the correct answer.

Explanation:

A compound when dissolved in a liquid or solution dissociates into ions then it is known as an electrolyte.

An ionic compound will always be an electrolyte.

For example, sodium hydroxide being an ionic compound will readily dissociate into ions when dissolved in water.

Hence, sodium hydroxide is able to conduct electricity. Therefore, it is an electrolyte.

Acetaldehyde is a substance commonly used in chemical factories. It is often produced by

Eduardwww [97]

There are 48 hydrogen atoms, 24 carbon atoms, and 12 oxygen atoms, also 12 molecules of acetaldehyde were produced in the reaction.

The equation of the reaction is;

12C2H4 + 6O2 ------> 12 CH3CHO

In order to approach this problem, the balanced reaction equation is the first step. There are 12 ethylene molecules and six oxygen molecules. These will combine as shown.

There number of atoms involved are as follows;

H = 48

C = 24

O = 12

There are 12 molecules of acetaldehyde produced in the reaction.

The equilibrium constant, Kc, for the following reaction is 83.3 at 500 K. PCl3(g) Cl2(g) PCl5(g) Calculate the equilibrium conc

Alik [6]

Answer:

$[PCl_3]=[Cl_2]=0.068M$

$[PCl_5]=0.385M$

Explanation:

Hello!

In this case, since the equilibrium expression for the considered equation is:

$Kc=\frac{[PCl_5]}{[Cl_2][PCl_3]}$

Which can be written in terms of the reaction extent and the ICE chart and the initial concentrations of 0.453 M as shown below:

$83.3=\frac{x}{(0.453M-x)(0.453M-x)}$

We can solve for x as follows:

$x=0.385M$

In such a way, we obtain the following concentrations at equilibrium:

$[PCl_3]=[Cl_2]=0.453M-0.385M=0.068M$

$[PCl_5]=0.385M$

Best regards!

Assume that 8.5 L of iodine gas (I2) are produced at STP according to the following balanced equation:2KI(aq) + Cl2(

Aliun [14]

Answer: 0.3794 moles of Iodine gas are produced.

Explanation:

$2KI(aq)+Cl_2(
g)\rightarrow 2KCl(aq)+I_2$

Volume of iodine gas produced at STP =8.5 L

At STP, the 1 mol of gas occupies volume = 22.4 L

So, 8.5 L of volume will be occupied by: $\frac{1}{22.4 L}\times 8.5=0.3794 moles$

0.3794 moles of Iodine gas are produced.
