Yes Compounds are generally made of two or more atom or ion or species!
TRUE
Explanation:
Assuming that moles of nitrogen present are 0.227 and moles of hydrogen are 0.681. And, initially there are 0.908 moles of gas particles.
This means that, for
moles of
+ moles of
= 0.908 mol
Since, 2 moles of
=
= 0.454 mol
As it is known that the ideal gas equation is PV = nRT
And, as the temperature and volume were kept constant, so we can write
=
= 
=
= 5.2 atm
Therefore, we can conclude that the expected pressure after the reaction was completed is 5.2 atm.
Answer:
The catalyzed reaction will take 1,41 s
Explanation:
The rate constant for a reaction is:

Assuming frequency factor is the same for both reactions (with and without catalyst) it is possible to obtain:

Replacing:


That means the reaction occurs 5,64x10¹⁰ faster than the uncatalyzed reaction, that is 2537 years / 5,64x10¹⁰ = 4,50x10⁻⁸ years. In seconds:
4,50x10⁻⁸ years×
