Answer:

The correct answer is option C.

Explanation:

Alpha radiations are emitted by alpha particles imparts less amount of energy to the absorbing material.

Where as beta radiation by beta particles are more penetrating than the alpha particles and gamma rays are most penetrating radiations they can even penetrate through out a human body.

The order of penetration of these radiations from least to most is :

Alpha rays < Beta rays < gamma rays

Hence, the correct answer is option C.

How the metals react with oxygen? Give the general formula and explain the reaction of sodium with oxygen with chemical equation

slamgirl [31]

Answer:

Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Sodium is the metal reacts vigorously with oxygen and water.

4 Na + O2 → 2 Na2O.

If an element has more than one ionic charge, how is that piece of information represented in a chemical name?

solmaris [256]

Usually with roman numerals, like iron (II) chromate
iron has a charge of 2
or manganese (IV) oxide, manganese has a charge of 4
(these are ionic compounds just to let you know)

The vapor pressure of liquid acetone, CH3COCH3, is 100 mm Hg at 281 K. A 6.06E-2 g sample of liquid CH3COCH3 is placed in a clos

Lynna [10]

Explanation:

According to ideal gas equation, product of pressure and volume equals the product of number of moles, gas constant and temperature.

Mathematically, PV = nRT

where P = pressure, V = volume

n = no. of moles, R = gas constant = 0.0821 atm L/mol

T = temperature

Since, it is known that number of moles equal mass divided by molar mass.

Hence, number of moles of given sample of acetone are as follows.

No. of moles = $\frac{mass}{\text{molar mass of acetone}}$

= $\frac{6.06 \times 10^{-2}}{58 g/mol}$

= $0.104 \times 10^{-2}$ mole

Therefore, putting the values in ideal gas equation as follows.

PV = nRT

$P \times 0.36 L = 0.104 \times 10^{-2} \times 0.082 atm L/mol \times 281 K$

= 0.359 atm

In 1 atm equal to 760 mm Hg. So, convert 0.359 atm into mm Hg as follows.

$0.359 atm \times \frac{760 mm Hg}{1 atm}$

= 272.84 mm Hg

Hence, pressure of the ideal gas will be 100 mm Hg + 272.84 mm Hg = 372.84 mm Hg

Thus, we can conclude that the ideal gas pressure in the container if all of the liquid acetone evaporated is 372.84 mm Hg.

I WILL RATE BRAINLIEST!!!! NEED QUICK HELP!!!!

Alik [6]

You will need the Gas Law:

pV = nRT

Since T and p are constant, R is constant too, then moles increases->volume will increase with the same ratio too!
