Answer:
It can enhance survival because the animals for example birds are migrating to those places for high or increasing resources
Explanation:
Molar mass of Na = 23 g/mol
Molar massa of Na2O = 62 g/mol
balanced chemical equation:
4 Na +
1 O2 ------>
2 Na2O
4 . 23 g Na --------------> 2 . 62 g Na2O
x -------------------------> 42,0 g Na2O
124 x = 3864
![x = \frac{3864}{124}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B3864%7D%7B124%7D%20)
![x = 31,16 g](https://tex.z-dn.net/?f=x%20%3D%2031%2C16%20g%20)
of Na
It means there is a lot of the same thing and not many others
H2SO4/H2O
H2SO4/Na2SO4
NaOH/H20
NaOH/Na2SO4
Correct answer is H2SO4/Na2SO4
We know, Weight = Mass * Gravity
Here, Mass = 20 Kg
Gravity = 10 m/s² [Approximate value ]
Substitute their values,
w = 20 * 10
w = 200 N
In short, Your Answer would be Option C
Hope this helps!
