(c) chromium(III) oxide with dilute hydrochloric acid,

According to reaction,1 mole of chromium(III) oxide reacts with 6 moles of hydrochloric acid to give 2 moles of chromium(III) chloride and 3 moles of water.
(d) selenium dioxide with aqueous potassium hydroxide

According to reaction,1 mole of selenium dioxide reacts with 2 moles of potassium hydroxide to give 1 mole of potassium selenite and 1 mole of water.
Answer:
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
Explanation:
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named trypsin:
- Glu-Gly-Lys,
- Gln-Val-Ile
- Ala-Ser-Phe-Lys
Fragments obtained on hydrolysis of decapeptide P by the action of an enzyme named chymotrypsin:
- Lys-Gln-Val-Ile,
- Glu-Gly-Lys-Ala-Ser-Phe
In order to determine the sequence of protein P , we will arrange fragments in such a way so that common fragments or the common parts of fragments should come under each other.
On arranging these fragments :
Glu-Gly-Lys-Ala-Ser-Phe
Glu-Gly-Lys
Ala-Ser-Phe-Lys
Lys-Gln-Val-Ile
Gln-Val-Ile
The sequence of an amino acid P is:
Glu-Gly-Lys-Ala-Ser-Phe-Lys-Gln-Val-Ile
<span>In order to solve this problem you must first make sure all your numbers are in like terms. From the density value you can see that it is grams per liter. The first conversion you must do in convert the 125.0 mL value to Liters which you would do by dividing by 1000 because 1 liter is equal to 1000 mL. 125.0 divided by 1000 is 0.125 Liter. Now you will use the density equation to solve. The density equation is density is equal to mass divided by volume. Plug in your known numbers for density and volume. Then solve for mass. So Density (1.269 g/l is equal to mass divided by volume (.125 Liter) You must rearrange the equation to multiple density by volume which is 1.269 times 0.125 which will give you 0.1586. Because the Liters cancel each other out, the answer's unit will be grams. Your final answer is 0.1586 grams.</span>
