Answer:
d. directly proportional to the number of moles of the gas.
Explanation:
The formula for the partial pressure of a gas is written as -
P = n * P ( total )
P = partial pressure of the gas ,
n = mole fraction of the gas ,
P ( total ) = Total pressure of the mixture of gas .
Hence , from the above equation ,
the partial pressure is directly proportional to the mole fraction , i.e. , on increasing the number of moles of gas , the partial pressure increases .

Answer:
Argon
Explanation:
The average kinetic energy of the particles in a gas is given by
where
m is the mass of the particles
v is their rms speed
The average kinetic energy of the particles in a gas can also be written as
where
k is the Boltzmann's constant
T is the absolute temperature of the gas
Combining the two equations,
We can re-write the equation as
We see that:
- The speed is directly proportional to the square root of the temperature
- The speed is inversely proportional to the square root of the mass of the particles
Therefore, if the two gases are at same temperature, the particles will move faster in the gas with lighter particles (smaller mass).
Since Krypton atoms have larger mass than Argon atoms, it means that atoms in Argon move faster than in Krypton.
I think it's 3 % of the body.
Answer: Group 16 elements form ions with a 2 - charge.
Explanation: Therefore each of these elements would gain one electron and become an anion with 1 - charge.
