Answer:
represents the additional driving force required to overcome barriers such as the large activation energy for the formation of a gas at a metal surface.
Answer:
magnification makes everything smaller so you can see smaller things up close and study them more
Explanation:
Yes hydrogen is a non metal
Answer: The volume of the sample after the reaction takes place is 29.25 L.
Explanation:
The given reaction equation is as follows.

So, moles of product formed are calculated as follows.
Hence, the given data is as follows.
= 0.17 mol,
= 0.255 mol
= 19.5 L, 
As the temperature and pressure are constant. Hence, formula used to calculate the volume of sample after the reaction is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the volume of the sample after the reaction takes place is 29.25 L.
