Answer:
B
Explanation:
Bad conductor of elecricity
The name of the compound K3N is potassium nitride (C).
Answer:
Nuclear fusion
Explanation:
Nuclear fusion is the source of Sun's energy.. At the core where temperature and pressure are very high hydrogen atoms fuse into helium atom and release energy in the form of Gama rays.
In an ideal gas, there are no attractive forces between the gas molecules, and there is no rotation or vibration within the molecules. The kinetic energy of the translational motion of an ideal gas depends on its temperature. The formula for the kinetic energy of a gas defines the average kinetic energy per molecule. The kinetic energy is measured in Joules (J), and the temperature is measured in Kelvin (K).
K = average kinetic energy per molecule of gas (J)
kB = Boltzmann's constant ()
T = temperature (k)
Kinetic Energy of Gas Formula Questions:
1) Standard Temperature is defined to be . What is the average translational kinetic energy of a single molecule of an ideal gas at Standard Temperature?
Answer: The average translational kinetic energy of a molecule of an ideal gas can be found using the formula:
The average translational kinetic energy of a single molecule of an ideal gas is (Joules).
2) One mole (mol) of any substance consists of molecules (Avogadro's number). What is the translational kinetic energy of of an ideal gas at ?
Answer: The translational kinetic energy of of an ideal gas can be found by multiplying the formula for the average translational kinetic energy by the number of molecules in the sample. The number of molecules is times Avogadro's number:
Answer:
The mass of P₄O₁₀ (s) formed is 471.03 g
Explanation:
4PH₃(g) + 8O₂(g) → P₄O₁₀ (s) + 6H₂O (g)
This is the ballanced equation.
Every 4 moles of phosphine, 1 mol of tetraphosphorus decaoxide is generated.
Moles of PH₃ = Mass PH₃ / Molar mass PH₃
Moles PH₃ = 225 g / 33.9 g/m
Moles PH₃ = 6.63 moles
So the rule of three, will be:
If 4 moles of PH₃ generate 1 mol P₄O₁₀
Then, 6.63 moles of PH₃ generate (6.63 .1)/4 = 1.66 moles
If we want to know the mass:
Moles . Molar mass = mass
Molar mass P₄O₁₀ = 283.88 g/m
1.66m . 283.88 g/m = 471.03 g
