Answer:
Explanation:
The reasons that cities boomed during the Middle Ages are more employment opportunities, increased trade, and growing interest in culture and art.
Answer:
In 1 mol of anything, you have 6.02×10²³ particles, so 1 mol of F₂ contains 6.02×10²³ molecules.
Hydrocarbon, to my knowledge is an organic compound consisting mainly of hydrogen and carbon. It is mainly found in petroleum and natural gas. Hope this helps!
The first bubble after "water evaporates" should be something along the lines of that the water condenses in the clouds and then the following bubble should be that the water is released from the clouds. Does that make sense to you?
Explanation:
First, we will calculate the molar mass of
as follows.
Molar mass of
=
= 78 g/mol
So, when 2 mol of
burns, then heat produced = 6542 KJ
Hence, this means that 2 molecules of
are equal to
of
burns, heat produced = 6542 KJ
Therefore, heat produced by burning 5.5 g of
=
= 228.97 kJ
= 228970 J (as 1 kJ = 1000 J)
It if given that for water, m = 5691 g
And, we know that specific heat capacity of water is 4.186
.
As, Q =
228970 J = 

Thus, we can conclude that the final temperature of the water is
.
