What allows transgenic salmon to grow in the winter months?
1 answer:
Answer:
An aquaculture company called AquaBounty Farms has produced the first transgenic animal intended for human consumption: Atlantic salmon with two donor genes from other fish. The donated genes keep the transgenic salmon growing year-round, instead of taking a winter break, so they reach adult size faster than normal.

Given parameters:
Mass of Na = 275g
Unknown:
Number of molecules of Na₂O =
Solution:
Since sodium is the limiting reactant, we first use it to find the number of mole of the Na₂O and transpose it into finding the number of molecules.
Given equation:
4Na + O₂ → 2Na₂O
Since the equation is balanced, let us find the number of moles of Na;
Number of moles = =
= 11.96moles
From the equation of the reaction;
4 mole of Na produced 2 moles of Na₂O
11.96 moles of Na will produce = 6moles
1 mole of a substance = 6.02 x 10²³ molecules
6 moles of Na₂O = 6 x 6.02 x 10²³ molecules = 3.6 x 10²⁴molecules

Explanation:
Hello.
In this case, since the electron configuration of potassium whose atomic number is 19 turns out:
We can see that the last level is 4 which has one electron, meaning that potassium has one valence electron. Moreover, since bromine's atomic number is 35, its electron configuration is:
We can see that the last level is also 4 and it has 2+5 = 7 valence electrons. In such a way, we infer that the valence electrons are computed by the electrons at the outer or last energy level of an element.
