Here's what I get
Explanation:
A condensation reaction joins two larger molecules by splitting out a smaller molecule — usually water or ammonia — between them.
In an esterification reaction, an OH from the acid and an H from the alcohol form a molecule of water.
The larger parts join to form the ester.
Ethanol and butanoic acid react to form ethyl butanoate.
Answer:
869.93J/g°C
Explanation:
From the question given, we obtained the following:
M = 42.6g
T1 = 12°C
T2 = 46°C
ΔT = T2 — T1 = 46 — 12 = 34°C
C =?
Q = 1260 KJ = 1260000J
Q = MCΔT
C = Q / MΔT
C = 1260000 /(42.6 x 34)
C = 869.93J/g°C
Therefore, the specific heat capacity is 869.93J/g°C
Answer:
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula. Only the hot core of the star remains. ... That means a white dwarf is 200,000 times as dense.
Explanation:
they are cold
they are about the size of Earth
these both are not true
