<span>A single-replacement reaction</span>
Explanation:
The given data is as follows.
Moles of propylene = 100 moles,
= 300 K
= 800 K,
,
of propylene = 100 J/mol
Now, we assume the following assumptions:
Since, it is a compression process therefore, work will be done on the system. And, work done will be equal to the heat energy liberating without any friction.
W = 

= 
= 5 MJ
Thus, we can conclude that a minimum of 5 MJ work is required without any friction.
He discovered choice C! this is because atoms of the same element can have different numbers of neutrons
Ba(OH)₂ = 137.3 + 16 x 2 + 1 x 2 = 171.3 g
Answer (3)
hope this helps!
I’m not really sure just trying to get points but maybe it’s length
