What is the volume occupied by 0.108 mol of helium gas at a pressure of 0.909 atm and a temperature of 306 K ? Express your answer using three significant figures. Would the volume be different if the gas was argon (under the same conditions)? The volume would be the lower for argon gas. The volume would be the same for argon gas. The volume would be the greater for argon gas.

Answer:

Answer: 2.93 L

To find the volume occupied by 0.108 mol of helium gas at a pressure of 0.909 atm and a temperature of 306 K, we can use the ideal gas law equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.

Rearranging the equation to solve for V:

V = (nRT) / P

Plugging in the given values:

n = 0.108 mol

R = 0.0821 L·atm/(mol·K) (the ideal gas constant)

T = 306 K

P = 0.909 atm

V = (0.108 mol * 0.0821 L·atm/(mol·K) * 306 K) / 0.909 atm

Calculating this expression, we find that the volume occupied by 0.108 mol of helium gas at a pressure of 0.909 atm and a temperature of 306 K is approximately 2.93 L.

Now, let's consider the second part of the question: Would the volume be different if the gas was argon (under the same conditions)?

The volume would be the same for argon gas.

According to the ideal gas law, at the same temperature, pressure, and number of moles, the volume occupied by a gas is the same regardless of the gas's identity. Therefore, if we replaced helium gas with argon gas while keeping the same conditions of pressure, temperature, and number of moles, the volume occupied by argon gas would be the same, approximately 2.93 L.

C) The alkali metal atom has one less shell of electrons than the atom of the alkaline earth metal.
D) The alkali metal atom has one more shell of electrons than the atom of the alkaline earth metal.

Answers

Answer: The correct answer is Option A.

Explanation:

Chemical reactivity is defined as the tendency of an atom to loose or gain electrons.

Metals are the elements that looses electrons and thus, their chemical reactivity will be the tendency to loose electrons.

Their chemical reactivity decreases as we move from left to right in a period. This is so because, the electron get added up in the same shell. So, the electron in the outermost orbital gets more tightly bonded to nucleus. And hence, loosing an electron will require high energy. Thus, the chemical reactivity decreases.

  • Alkali metals are the elements which belong to group 1 of the periodic table. The general electronic configuration of these metals is ns^1

These metals will loose 1 electron to form +1 ions.

  • Alkaline earth metals are the elements which belong to group 2 of the periodic table. The general electronic configuration of these metals is ns^2

These metals will loose 2 electrons to form +2 ions.

Hence, the correct answer is Option A.

A) The alkali metal atoms forms a +1 ion, while the alkaline eaeth metal atom forms a +2 ion.

Ketone bodies

Explanation;

  • Ketone bodies are produced by the liver and used peripherally as an energy source when glucose is not readily available.
  • They are produced from acetyl-CoA, mainly in the mitochondrial matrix of liver cells when carbohydrates are so scarce that energy must be obtained from breaking down of fatty acids.
  • Tissues that can use fatty acids can generally use ketone bodies in addition to other energy sources. The exceptions are the liver and the brain.
