Answer:
The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts. The first part is called the duodenum.
Explanation:
1.5 M KNO3 - both solutions contain KNO3, but the one with higher concentration is 1.5 M, as 1.5 M > 1.0 M. 1.0 M also increases the boiling point, but not to as great an extent as 1.5 M does.
Answer:
(a) -134 kJ (b) -136 kJ
Explanation:
a) Using the accounting of the enthalpy of broken and formed bonds we will have the answer for this question ( remember the enthalpy of bonds broken are positive and those formed are negative)
ΔHrxn(kJ) = 6H (C-H) + 1 (C-C)+ 1H (H) + 1(C=C) + 4(C-H)
= 6(-411) +(-346) +432 + 602 + 4(411)
= - 134 kJ
(b) ΔHrxn = ΔHºf(C2H6) - ΔHºf (C2H4) = -83.75 kJ- 52.3 kJ = -136 kJ
( ΔHºf (H2)) = 0)
