Given the mass of the gas, temperature and volume of the cylinder, the pressure of the Carbon dioxide gas is 38.7atm.

<h3>What is Ideal Gas Law?</h3>

The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.

It is expressed as;

PV = nRT

Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )

Given that;

  • Mass of Carbon dioxide = 78.5g
  • Molar mass of Carbon dioxide 44.01 g/mol
  • Amount of gas n = 78.5g ÷ 44.01 g/mol = 1.78mol
  • Volume L = 1.2L
  • Temperature T = 45.1°C = 318.25K
  • Pressure P = ?

PV = nRT

P = nRT / V

P = ( 1.78mol × 0.08206 Latm/molK × 318.25K ) /  1.2L

P = 46.4857591Latm / 1.2L

P = 38.7atm

Therefore, given the mass of the gas, temperature and volume of the cylinder, the pressure of the Carbon dioxide gas is 38.7atm.

What does n, l and s mean in chemistry?
kirill [66]

Answer:

These three numbers, n, ℓ, and s can be used to describe an electron in a stable atom.

Explanation:

Each electron's quantum numbers are unique and cannot be shared by another electron in that atom. This property is called the Pauli Exclusion Principle.

Hope this helps!!! :)))

11. What are transition metals?
kolezko [41]

Answer:

Elements that fall between those on the left and right sides of the periodic table

Explanation:

Transition metals:

These are present at the center of periodic table.

These are d-block elements.

They include the elements of group 3 to 12 in periodic table.

They have large charge to radius ratio.

They mostly form paramagnetic compounds.

They shoes more than one oxidation state.

They form colored compounds.

They all have high melting and boiling point.

They have high densities.

They form stable complexes.

The elements of f-block are also transition but they are called inner transition.These are consist of two series lanthanide and actinides.
