Answer: gaseous molecules are far apart
Explanation:
One of the states in which matter exists is gas. Gases are made of up molecules that are far apart, travelling randomly and rapidly within the containing vessel.
Hence, they are easy to compress whereby they occupy limited space as the gaseous molecules are closely packed in vessels like cylinders and transported to places where they may be needed.
Answer:
Not doubled
Explanation:
The equation below represent the ideal gases relationship
PV ÷ T = constant
Here
P denotes pressure,
V denotes volume,
T denotes temperature in degrees Kelvin
Now
20 ° c = 273 + 20
= 293 K
And,
40 ° c = 313 K
So,
V = Vo. 313 K ÷ 293 K = 1.07 Vo
So, the volume is NOT doubled.
In the case when the temperature would be determined in degrees celsius at 0 degrees so the volume would be zero
If you have 9 moles of hydrogen gas(H2) the moles of water that can be formed is 9 moles
<u><em>calculation</em></u>
2H2 +O2→ 2H2O
The mole of H2O is calculated using the mole ratio.
that is H2:H2O is 2:2 into simple form = 1:1
therefore if 9 moles of H2 reacted the moles of H2O = 9 x1/1 = 9 moles
