There are four choices to choose from in regards with this problem and fortunately I know the answer to the said question:

Listed below are the choices:

a.) 6.0 L of H2(g) at STP
b.) 12.0 L of CO2(g) at STP
c.) 18.0 L of HCI(g) at STP
d.) 24.0 L of O2(g) at STP

The correct answer is b. 12.0 L of CO2 (g) at STP


Note:

STP or (Standard Temperature and Pressure) - most commonly used when performing calculations on gases (e.g. gas density)

Options Given:

a. 6.0 L of H₂(g) at STP
b. 12.0 L of CO₂(g) at STP
c. 18.0 L of HCI(g) at STP
d. 24.0 L of O₂(g) at STP

Answer:

            Option-B is the correct answer.


Explanation:

                   As we know that any gas ( 1 mole) at standard temperature (273 K or 0 °C) and pressure (1 atm) occupies exactly 22.4 L of volume.

                   Therefore, at standard conditions 12 L of CH₄ containing 3.22 × 10²³ molecules will be equal to number of molecules (3.22 × 10²³) contained by 12 L of CO₂ as both the volumes are the same.

What does charles law state​
Feliz [49]

Answer: Charles' Law is a special case of the ideal gas law. It states that the volume of a fixed mass of a gas is directly proportional to the temperature. This law applies to ideal gases held at a constant pressure, where only the volume and temperature are allowed to change.

Which of the following is the best hypothesis?
DerKrebs [107]

Answer:

B.) If sodium carbonate is added to vinegar, the reaction will absorb heat.

Explanation:

A.) is incorrect because this is not testable. Rather, it is just an opinion that cannot be proven correct or incorrect.

B.) is correct because this statement is testable. Tests need to be run to determine the accuracy of the statement.

C.) is incorrect because this statement explains something that does not need to be tested. It is an example of a physical change when one tears a piece of paper.

D.) is incorrect because this is already a true statement. It is obvious that not all reactions absorb/release heat. While tests could be run to further prove this statement true, it is already considered accurate.

gayaneshka [121]
There are three types of artificial cloning:
Gene cloning: copies a few segments of DNA or genes.
Reproductive cloning: it copies the whole animal.
Therapeutic cloning: produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.

If I have 1.9 moles of gas held at a pressure of 5 atm and in a container with a volume of 100 liters, what is the temperature o
Ivahew [28]

Answer:

T = 3206.89 K

Explanation:

Given that,

Number of moles, n = 1.9 moles

Pressure, P = 5 atm

Volume, V = 100 L

We need to find the temperature of the gas. Let the temperature is T. We know that,

PV = nRT

Where

R is gas constant, R = 0.08206 L-atm/mol-K

Put all the values,

T=\dfrac{PV}{nR}\\\\T=\dfrac{5\times 100}{1.9\times 0.08206 }\\\\T=3206.89\ K

So, the temperature of the gas is 3206.89 K.
