The properties of noble gases include:
- They are nonreactive
- They have hight ionisation energy
- They have low boiling point
- They conduct electricity at low pressure.
The noble gases are those elements that makes up the group 18 of the periodic table.
They are non as the inert gases because they are relatively nonreactive.
According to the electronic arrangement, which is according to how the electrons are arranged on their shells, they can exist alone.
The noble gases are nonreactive, have high ionisation energy and low boiling point because in its electronic arrangement, the outer shell is completely full.

This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.
Answer:
Potassium compounds are quite common and are extremely useful for a variety of purposes. Potash and other potassium compounds have been used for centuries in the manufacture of glass products. Today 95% of the potassium compounds gathered in the world is used in the manufacture of fertilizers.
Potassium dichromate is an inorganic chemical compound possess immense industrial and laboratory importance. It is an orange crystalline solid with the chemical formula K2Cr2O7. It is a strong oxidizing agent and is soluble in water. It is used in the volumetric estimation of ferrous salts, iodides and sulphides for the preparation of chrome alum, chrome yellow and chrome red.
To keep burning, fires require oxygen. Carbon dioxide is used in certain fire extinguishers to put out flames. Explanation: Because magnesium is higher on the reactivity scale than carbon, it is more reactive and eliminates oxygen from carbon dioxide (to give carbon and magnesium oxide).

Explicación:
Paso 1: Calcular los moles de gas
Una garrafa contiene 9 L de gas a 18°C (291 K) y 780 Torr. Podemos encontrar los moles de gas (n) usando la ecuación del gas ideal.
P × V = n × R × T
n = P × V/R × T
n = 780 torr × 9 L/(62,4 Torr.L/mol.K)/ × 291 K = 0.387 mol
Paso 2: Calcular la masa molar del gas
El gas tiene una densidad (ρ) de 2 g/L a 80 °C (353 K) y 1,5 atm. Podemos calcular la masa molar (M) del gas usando la siguiente fórmula.
ρ = P × M / R × T
M = ρ × R × T / P
M = 2 g/L × (0.082 atm.L/mol.K) × 353 K / 1,5 atm = 38,59 g/mol
Paso 3: Calcular la masa del gas (m)
Usaremos la siguiente formula.
m = n × M = 0.387 mol × 38,59 g/mol = 14,9 g
