Answer:The new volume will be
0.7 L
Explanation:
This is an example of Charles' law, sometimes called the temperature-volume law. It states that the volume of a gas is directly proportional to the Kelvin temperature, while pressure and amount are held constant.
The equation is
V

, where
V
is volume and
T
is temperature in Kelvins.

Answer:
2NaCl > Cl2 + 2Na
Explanation:
2 moles of sodium chloride is irreversible to chlorine gas plus 2 moles of solid sodium
Step by step solution:
Its given;
Moles of neon at STP is 15 mol
We are required to calculate the volume;
According to molar gas volume, 1 mole of a gas occupies a volume of 22.4 liters at STP.
That is, 1 mole of a gas = 2.4 L
Therefore;
1 mole of Neon gas = 22.4 L
Volume = Moles of the gas × molar gas volume
= 15 mol × 22.4 L/mol
= 336 L
