Explanation:
to remind people that atoms were
I believe there are 0 atoms
Answer:
19,199,280 grams
Explanation:
0.062502343837894 grams in one mole of oxygen
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
.
Well, the colder something is, the less the molecules move around, making it harder for the substance to move
think of it as this:
extremely hot water=steam/gas, moves quickly
room tempurature=liquid, moves slower than steam/gas
frozen=solid, moves very slowly, if even
the colder it is, the slower water moves
