Answer:
185.92 L
Explanation:
Given data:
1 mole = 6.022× 10²³ molecules
1 mole = 22.4 L
Volume occupy by 5.0× 10²⁴ molecules
Solution:
1 mole = 6.022× 10²³ molecules
5.0× 10²⁴ molecules × 1 mole / 6.022× 10²³ molecules
0.83× 10¹ mol
8.3 moles
1 mole occupy 22.4 L
8.3 mol × 22.4 L / 1 mol
185.92 L
Answer:
Only number of electrons of Chlorine and argon are going to be same remaining things like mass,reactivity,ionic radii, and so on will be different so if a chlorine gains a electron we can't call it argon!! chlorine is an diatomic gas, argon exist as monoatomic, chlorine can loose that electron and form bond with another cation in order to remove the charge density,, but argon is stable itself!
Answer: 20.1 kg.
Explanation:
To calculate mass of a substance, we use the equation:
We are given:
Density of gasoline = 
Volume of gasoline = 
(Conversion factor: 
)
Putting values in above equation, we get:
The rule apply for multiplication and division is :
The least precise number present after the decimal point determines the number of significant figures in the answer, thus the answer musty have three significant digits.
Hence, the mass added is 20.1 kg.
Answer:
1
Explanation:
N2 + 3H2 → 2NH3
From the above equation,
There are 2 atoms of N on both side of equation and also, there are a total of 6 atoms of H on both side of the equation. Therefore, the equation is balanced.
The coefficient of N2 is 1
Answer:
D
Explanation:
Me has the least boiling point because it has the weakest degree of intermolecular forces. The weak van Der Waals forces exist in C2H6. In CH3OH, there are strong hydrogen bonds which accounts for the higher boiling point. NaNO3 is an ionic compound, hence it has the highest boiling point among all the substances mentioned.
