A polypeptide is a peptide composed of two amino-acid and a peptide bond is a chemical bond formed between two molecules, when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water.
Answer:
solidification
And when a solid turn into liquid it's liquidation
Answer:
The final temperature of the system is 42.46°C.
Explanation:
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
c = specific heat of water= 
= mass of water sample with 100 °C= 50.0 g
= mass of water sample with 13.7 °C= 100.0 g
= final temperature of system
= initial temperature of 50 g of water sample= 
= initial temperature of 100 g of water =
Now put all the given values in the given formula, we get


The final temperature of the system is 42.46°C.
Answer:
Bathtub
Explanation:
Even though the water in a filled bathtub may be at the same temperature as water in a glass, the water in the bathtub has more thermal energy because it contains a greater number of water molecules.
ANSWER - 48.83%
Mg - 24.31
S - 32.07
O - 16x4 - 64
ADD ALL TOGETHER = 120.38
H - 1.01x2 - 2.02
O - 16
TOTAL = 18.02x7 = 126.14
ADD 120.38 to 126.14 = 246.52
last part divide MgSO4 by total compound mass
120.38/246.52 then multiply by 100 = 48.831
