Answer:
1. Mass of potassium (K) = 203.32 g
2. Number of mole of As = 7.53 moles
Explanation:
1. Determination of the mass of potassium (K)
Molar mass of K = 39.1 g/mol
Number of mole of K = 5.2 moles
Mass of K =.?
Mole = mass / Molar mass
5.2 = mass of K / 39.1
Cross multiply
Mass of K = 5.2 × 39.1
Mass of potassium (K) = 203.32 g
2. Determination of the number of mole of Arsenic (As)
Molar mass of As = 74.92 g/mol
Mass of As = 563.9 g
Number of mole of As =.?
Mole = mass /Molar mass
Number of mole of As = 563.9 / 74.92
Number of mole of As = 7.53 moles
Coefficient of O2 will be 6
A green rat snake that lives in the grass and a brown rat snake that lives in the desert is a form of geographically separated species.
Explanation:
The habitats of the green rat snake and brown rat snake shows that they are geographically separated species.
The two rat snakes are different species because of their distinct habitat and morphology.
When two species get separated by habitat their breeding method changes either by morphology or breeding pattern.
Such species do not produce viable offspring.
Thus a green rat snake and a brown rat snake have very different habitats they are now two different species.
Such species are said to be reproductively isolated species. Two species having genetic divergence undergo natural selection to adapt to the environment.
