The correct answer is all of the above.  

Nuclear or radioactive radiation or radioactive decay refers to the procedure by which an unstable atomic nucleus loses energy in the form of mass in its rest frame by discharging radiation like a beta particle, alpha particle, or a gamma ray. A substance comprising such unstable nuclei is regarded as radioactive. The process does not need any input of energy.

1. If a solution of sodium chloride has 22.3 g of
lina2011 [118]

<u>We are given:</u>

Mass of NaCl in the given solution = 22.3 grams

Volume of the given solution = 2 L

<u></u>

<u>Number of Moles of NaCl:</u>

We know that the number of moles = Given mass / Molar mass

Number of moles = 22.3 / 58.44 = 0.382 moles

<u></u>

<u>Molarity of NaCl in the Given solution:</u>

We know that Molarity of a solution = Moles of Solute / Volume of Solution(in L)

Molarity = 0.382 / 2

Molarity = 0.191 M

The pressure of a sample of argon gas was increased from 3.14 atm to 7.98 at a constant temperature. If the final volume of argo
noname [10]

Answer:

<h2>36.09 L</h2>

Explanation:

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

P_1V_1 = P_2V_2

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume.

Since we're finding the initial volume

V_1 =  \frac{P_2V_2}{P_1}  \\

We have

V_1 =  \frac{7.98 \times 14.2}{3.14} =   \frac{113.316}{3.14}  \\  = 36.0878...

We have the final answer as

<h3>36.09 L</h3>

Hope this helps you
