0.10 mol of argon gas is admitted to an evacuated 50 cm3 container at 20°C. The gas then undergoes heating at constant volume to
dolphi86 [110]

<u>Answer:</u> The final pressure of the gas is 9.41 atm

<u>Explanation:</u>

To calculate the pressure of the gas, we use the equation given by ideal gas equation:

PV=nRT

where,

P = pressure of the gas = ?

V = Volume of gas = 50cm^3=0.05L    (Conversion factor:  1L=1000cm^3 )

n = Number of moles = 0.01 mol

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the gas = 300^oC=[300+273]K=573K

Putting values in above equation, we get:

P\times 0.050L=0.01\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 573K\\\\P=\frac{0.01\times 0.0821\times 573}{0.05}=9.41atm

Hence, the final pressure of the gas is 9.41 atm

Briefly describe how a potentiometric pHmeter works. (Hint: Describe how the pH meter
liq [111]

Answer:

A general instrument, which is used to determine the concentration of hydrogen ion within the aqueous solution is known as a pH meter. The meter helps in determining the alkalinity or acidity, which is articulated in the form of pH. It is also called a potentiometric pH meter as it helps in finding the variation in electrical potential between a reference electrode and a pH electrode. This electrical potential variation is associated with the pH of the solution.  

The potentiometric pH meter comprises a pair of electrodes and a basic electronic amplifier, some may even comprise a combination electrode and some sort of display that demonstrates pH units. The potentiometric pH meter generally exhibits a reference electrode or a combination electrode, and a glass electrode. The probes or electrodes are administered within a solution whose pH values are needed to be determined.

What is the difference between Nuclear Fission and Nuclear Fusion? Also any examples of them
stealth61 [152]

Answer:

Hiya there!

Explanation:

Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.

For example, uranium can fission to yield strontium and krypton. Fusion joins atomic nuclei together. The element formed has more neutrons or more protons than that of the starting material. For example, hydrogen and hydrogen can fuse to form helium.

<em><u>Hope this helped!</u></em> :D
