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.
A fish is a living thing and a rock is not
Answer:
f. Sn^4+
c. second
e. Al^3+
d. third
Explanation:
This question comes from a quantitative analysis showing the flowchart of a common scheme for identifying cations.
Now, from the separation scheme, Let's assume that Sn⁴⁺ & Al³⁺ were given; Then, Yes, the separation will work.
However, there will be occurrence of precipitation after the 1st step1.
So, the <u>Sn⁴⁺</u> cation will precipitate after the <u>second </u>step. Then the <u>Al³⁺</u> cation will precipitate after the <u>third</u> step.

Explanation:
Change in the concentration of reactant that is consumed in per unit time is known as rate of reaction.
The given chemical reaction will be written as follows.

Hence, rate law for the given reaction will be as follows.
Rate = k
where, k = rate constant
= initial pressure of the pollutant X
It is given that,
= initial partial pressure of X = 0.473 atm
= final partial pressure of X = 0.376 atm
Time = 5.6 hours
Hence, formula for rate constant of first order reaction is as follows.
k = 
= 
= 0.041 per hour
Therefore, rate of decomposition will be calculated as follows.
Rate =
= k
= 
= 
Thus, we can conclude that initial rate of decomposition of X is
.
