Answer: 177600 J or 177.6kJ
Explanation:
For this problem, we need to use q = mcAT
we have m = 10000, and AT= 40. The specific heat of iron is 0.444.
So now we can plug it in: q = 10000*.444*40 = 177600 J or 177.6kJ
IDensity is calculated by mass divided by volume. As you half the Hershey bar, mass and volume change by the same proportion. Therefore, density is the same.
Answer:
-191.7°C
Explanation:
P . V = n . R . T
That's the Ideal Gases Law. It can be useful to solve the question.
We replace data:
2.5 atm . 8 L = 3 mol . 0.082 L.atm/mol.K . T°
(2.5 atm . 8 L) / (3 mol . 0.082 L.atm/mol.K) = T°
T° = 81.3 K
We convert T° from K to C°
81.3K - 273 = -191.7°C
Electrolytes conduct electricity because they produce + and – ions in water
C6H12O6 and CH3CH2OH organic no ions
C6H12O6 and HCl sugar and hydrochloric acid
NaOH and HCl yields Na+1 ion and Cl-1 ion to conduct electricity
NaOH and CH3CH2OH
Hope this helps. :)
