The green areas on the diagram show the world's rainforests. What can you conclude about the location of rainforests?
Ber [7]

Answer:

Option A

They are located near the equator

Explanation:

From the diagram, we can observe that all the rain forest zones occur near the equator.

This is because on an annual basis, the equator receives the highest concentration of solar radiation in the whole Earth. This implies that the rate of evaporation of water from the water bodies present  is high, and consequently, the amount of rainfall is high also. This abundant sunshine and high rainfall  leads to the growth of the tropical rain forests at those regions

What is the mass number of an ion with 107 electrons, 157 neutrons, and a 1 charge?
Oksi-84 [34.3K]
265
your answer would be 265. Because the charge of +1 means there is one more proton then electron. So, 108 protons plus 157 neutrons gives you your mass number of 265.

Nadya [2.5K]

The question is incomplete , the complete question is;

The mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Wt-296  =  24.6622

Answer:

The atomic mass of Wt-296 is 195.9464 amu.

Explanation:

1 amu is defined as 1 by twelfth of the carbon-12 mass.

Mass of an isotope Wt-296 = 24.6622

Mass of an isotope Wt-296 in amu = M

M\times \frac{1}{12 amu}=24.6622

M=24.6622\times 12 amu=295.9464 amu

The atomic mass of Wt-296 is 195.9464 amu.
