The options are
<span>2, 3, 1
1, 3, 2
4, 3, 2
3, 2, 3
when balancing equation the masses should be balanced. In other </span>words the same number of atoms of the same element should be on either side of the equation
the balanced equation for the oxidation of aluminium is as follows
4Al + 3O₂ ---> 2Al₂O₃
coefficients are the numbers in front of the respective compounds.
the coefficients in the correct sequence are 4,3 and 2
answer is 4, 3, 2
Answer:
This is the balanced equation:
Pb(NO₃)₂ (aq) + 2NaI (aq) → 2NaNO₃ (aq) + PbI₂ (s) ↓
Explanation:
This are the reactants:
PbNO₃
NaI
Iodide can react to Pb²⁺ to make a solid compound.
Answer:
a. Leu-Ala-Arg-Phe-Val-Val-Lys
.
Explanation:
Hello.
In this case, considering the given data, we notice that the amino acid has a N-terminal Leu, that is why we first discard d. Moreover, considering the data (iii) and (v) we can infer that there are going to be two fragments by which it is possible to reason the proper sequence:
(iii): the amino acid has one section composed by Lys-Phe-Val-Val and another one by Ala, Arg, Leu that is why e is also discarded.
(v): the other two fragments are Ala, Arg, Leu, Phe, that is why b is discarded.
(iii) and (v): given the aforementioned fragments, we can combine them and therefore discard c, that is why the correct sequence is:
a. Leu-Ala-Arg-Phe-Val-Val-Lys
.
Best regards.
