Answer:vapor
Explanation: Because it is
Answer:
A.
Explanation:
Using the ideal gas equation, we can calculate the number of moles present. I.e
PV = nRT
Since all the parameters are equal for both gases, we can simply deduce that both has the same number of moles of gases.
The relationship between the mass of each sample and the number of moles can be seen in the relation below :
mass in grammes = molar mass in g/mol × number of moles.
Now , we have established that both have the same number of moles. For them to have the same mass, they must have the same molar masses which is not possible.
Hence option A is wrong
Atomic radio increases as number of valence electrons increase. Hence the first and fourth statement are wrong. Electronegativity is highest for elements on the TOP right hand corner of the periodic table so the third statement is wrong. Hence the answer is the third statement
