What is the combined gas law?

Chemistry
1 answer:
aliya0001 [1]2 years ago
8 0

Answer: The combined gas law is a combination of Boyle's Law and Charles' Law. The relationship between pressure, volume, and absolute temperature are all present in the combined gas law. It is written mathematically as:

PV/T=k (constant)

The constant, k, will also depend on the number of moles and could therefore vary. As long as the number of moles is constant, k, will be a true constant value.

Most combined gas law are worked with a before condition and an after condition. We typically number these conditions of state as 1 and 2 (sometimes initial and final also). So the working form of the combined gas law is:

P1V1/T1=P2V2/T2

Any units will work here for pressure and volume but the temperature must be absolute (Kelvin).

A student dropped a piece of nickel metal into a solution of HCl(aq). He observed the formation of gas bubbles and collected the
omeli [17]

Answer:

a. The student performed the splint test incorrectly. He should of observed a popping sound when the splint was placed in the test tube.

Explanation:

It is given that a student performed an experiment where he dropped a nickel metal in to HCl solution. He observed the reaction and performed a splint test in the test tube that is filled with a gas which is formed while Nickle is dropped into the solution of HCl.

But the experiment that the student performed was incorrect. He must have observed the popping sound when the splint was placed in the test tube.

When the splint was added to the gas splint flared up. The hydrogen gas pops out when exposed to the flame.

$Ni + HCl(aq) = NiCl + H_2$

Thus the correct option is (a).

Identify the mixture of powdered charcoal and powdered sugar and suggest a technique for separating their components
mihalych1998 [28]
A- Identify the mixture:
The mixture of powdered charcoal and powdered sugar is considered as a homogeneous mixture. This means that you cannot identify the components with naked eye as they are uniformly distributed in the mixture.

B- Separate components:
You ca separate the charcoal powder from the sugar powder using the following steps:
1- add water. Sugar will dissolve in water while charcoal won't.
2- filter the solution where the powdered charcoal will remain on the filter paper and the solution of powder will pass through.
3- boil the sugar solution (above 100 degrees celcius). The water will evaporate and the sugar will precipitate.

The pressure on 2.50 L of gas is changed from 4.5 atm to 2.2 atm. What is the new volume of gas?
swat32

Answer:

<h2>5.11 L</h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{2.5 \times 4.5}{2.2}  =  \frac{11.25}{2.2}  \\  = 5.1136666...

We have the final answer as

<h3>5.11 L</h3>

Hope this helps you
