Answer:
tropical rain forests and savannas
Explanation:
Tropical rainforests are found near the equator due to the amount of rainfall and the amount of sunshine these areas receive. ...
savannas-Because of their warm climate requirements, savannas tend to be found closer to the equator, which marks the halfway point between the north and south hemispheres of the earth. Because this area gets direct sunlight more of the year than the north and south extremes, the temperature doesn't change much.
A = mass number which is equal to the total number of protons + number of neutrons, Z= atomic number of any element which is also indicates Number of protons or number of electron in the given atom.
The formula to calculate neutron would be :
mass number - proton
31 - 15 = 16
Thus 16 neutrons are found in one atom of P
There are 4 atom in one molecule
Thus
4 atom /1 molecule * 9 molecule * 16 neutron / 1 atom
= 4*9*16= 576 neutrons

30 g SiO₂ (sand)
<u>Step 2: Identify Conversions</u>
Molar Mass of Si - 28.09 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of SiO₂ - 28.09 + 2(16.00) = 60.09 g/mol
