Answer:
0.02 moles.
Explanation:
volume of H₂ gas at R.T.P = 480 cm³
Where
R.T.P = room temperature and pressure
molar volume of gas at = 24000 cm³
no. of moles of hydrogen = ?
Solution:
formula Used
no. of moles = volume of gas / molar volume
put values in above equation
no. of moles = 480 cm³ / 24000 cm³/mol
no. of moles = 0.02 mol
So,
no. of moles of hydrogen in 480 cm³ is 0.02 moles.
Sodium is very reactive but it’s a metal, and the problem asks specifically for a non-metal.
Silicone is technically reactive, but not super reactive.
Argon is a nonmetal, however it is an inert gas. It doesn’t react with anything.
We’re left with Chlorine, which is a non-metal in group 7, a highly reactive group, on the periodic table.
Malleable, shiny and good conductors

Answer:
The correct option is;
A warm front is approaching the city and temperatures will increase
Explanation:
A low pressure forms by the movement of air away from a particular spot such that the pressure reduces. The movement of air away from a spot occurs when there is a boundary of warm and cold air such that the air moves to maintain a uniform temperature.
Low pressure centers are associated with warm fronts, resulting in the fall of barometric pressure or observed low pressure and are characterized by a rise in temperature.
