The correct answer is;
A mixture
Explanation:
A mixture is a substance made up of two or more distinct substances which are mixed. A mixture transfers to the physical mixture of two or more substances in which the personalities are retained and are incorporated in the form of solutions, discontinuing, and colloids.
The troposphere protect the molecules because there are higher layers on top. This makes life possible on Earth.
Answer:
Mass = 27.2 g
Explanation:
Given data:
Volume of gas = 22.7 L
Pressure of gas = 200.0 KPa (200/101=1.97 atm)
Temperature = 50.0°C
Mass of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
50+273 = 323K
1.97 atm ×22.7 L = n × 0.0821 atm.L/ mol.K × 323K
44.72 atm.L = n × 26.52 atm.L/ mol
n = 44.72 atm.L / 26.52 atm.L/ mol
n = 1.7 mol
Mass of CH₄:
Mass = number of moles × molar mass
Mass = 1.7 mol × 16 g/mol
Mass = 27.2 g
Answer:
two atoms share 1 pair of valenece electrons
Explanation:
because double bond is created when each of two atoms share 2 valenece electrons (1 pair of electrons = 2 electrons)

Answer:
At 13.6 C, a 1.2 mole sample of a gas exerts a pressure of 2.4 atmospheres. 1 point If you were solving for volume, what number would you use for temperature in the ideal gas law equation (PV = nRT)? о O 13.6 o 1.2 0 24 O 286.6 0 275.4
