Proton rays are the rays which can penetrate the most deeply into our body.

Answer: D

Explanation

The radiations are surrounding our atmosphere.

The radiations like alpha rays cannot penetrate dead skin cells while the beta rays can penetrate up to some layers of the skin.

The gamma rays are not a beam of energetic particles like alpha and beta rays, they are beam of energies released in order to stabilize the daughter nuclei.

But the rays which can penetrate more deeply in human body is proton rays and X-rays.

The proton rays are the beam of energetic protons which are positively charged.

They are heavy beam of energies.

The proton rays can penetrate the skin as well as reach the damage cells or tumor cells and they can cure them using proton therapy.

Could you please Calculate the number of atom of 40K (potassium 40) in 1gram of KCl. Taking into account the isotopic abundance

Crank

Answer:

$9.53*10^{17}$ atoms of 40K

Explanation:

You can use the molecular mass and the Avogadro´s number, in the following formula:

$N_{40K=\frac{m_{KCl}}{M_{MKCl}}}*N_{Avogadro}*(IA_{40k})$

where $m_{KCl}$ is the sample mass, $M_{KCl}$ is the molecular mass of the KCl and IA(40K) is the isotopic abundance of 40K.

Now replacing the values, you can find:

$N_{40K}=\frac{1g}{74.5513\frac{g}{mol}}*6.022*10^{23}mol^{-1} *0.000118$

$N_{40K}=9.53*10^{17} atoms$

A sample of oxygen gas in one container has a volume of 20.0mililiter at 297 K and 101.3 kPa. The entire sample is transferred t

VashaNatasha [74]

Answer: $V_2=\frac{101.3kPa\times 20.0ml\times 283K}{297K\times 94.6kPa}$

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

$V_2=\frac{P_1V_1T_2}{T_1P_2}$

where,

$P_1$ = initial pressure of gas = 101.3 kPa

$P_2$ = final pressure of gas = 94.6 kPa

$V_1$ = initial volume of gas = 20.0 ml

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $297K$

$T_2$ = final temperature of gas = $283K$

Now put all the given values in the above equation, we get the final volume of gas.

$V_2=\frac{101.3kPa\times 20.0ml\times 283K}{297K\times 94.6kPa}$

$V_2=20.4ml$

Thus the correct numerical setup for calculating the new volume is $\frac{101.3kPa\times 20.0ml\times 283K}{297K\times 94.6kPa}$
