Answer:

The new volume of the gas is 9.086 liters.

Explanation:

Let suppose that nitrogen has a behavior of ideal gas, the equation of state for ideal gases is:

P\cdot V = n \cdot R_{u}\cdot T (1)

Where:

P - Pressure, measured in atmospheres.

V - Volumen, measured in liters.

n - Molar amount, measured in moles.

T - Temperature, measured in Kelvin.

R_{u} - Ideal gas constant, measured in atmosphere-liters per mole-Kelvin.

If pressure and molar amount of the gas remain constant, then we construct the following relationship:

\frac{T_{1}}{V_{1}} = \frac{T_{2}}{V_{2}} (2)

If we know that T_{1} = 290.15\,K, P_{1} = 8.5\,L and T_{2} = 310.15\,K, then the new volume of the gas is:

V_{2} = \left(\frac{T_{2}}{T_{1}}\right)\cdot V_{1}

V_{2} = \left(\frac{310.15\,K}{290.15\,K} \right)\cdot (8.5\,L)

V_{2} = 9.086\,L

The new volume of the gas is 9.086 liters.

Answer:

1. Lanthanum-139 atom is the stable isotope of lanthanum with relative atomic mass 138.906348, 99.9 atom percent natural abundance and nuclear spin 7/2.

2. In fact, over 80% of electric cars sold globally utilized permanent magnet-based motors in 2019. These magnets are typically made with rare-earth materials such as neodymium and dysprosium, which have a very geographically constrained supply chain.

3. It is the second most reactive of the rare-earth metals after europium. Lanthanum oxidizes in air at room temperature to form La2O3. It slowly reacts with water and quickly dissolves in diluted acids, except hydrofluoric acid (HF) because of formation of a protective fluoride (LaF3) layer on the surface of the metal.
