This would be snow falling on a glacier since the <span>cryosphere has to do with frozen water on the surface of earth (AKA Glaciers) and the snow comes from the atmosphere. So we can say that snow and glaciers make an atmosphere-cryoshere interaction.</span>
Answer:
6.82 moles of Fe2O3
Explanation:
Step 1:
Determination of the number of mole of in 450g of CO2.
This is illustrated below:
Molar Mass of CO2 = 12 + (2x16) = 44g/mol
Mass of CO2 = 450g
Number of mole of CO2 =.?
Number of mole = Mass/Molar Mass
Number of mole of CO2 = 450/44 = 10.23 moles
Step 2:
Determination of the number of mole of Fe2O3 needed for the reaction. This is illustrated below:
2Fe2O3 + 3C—> 4Fe + 3CO2
From the balanced equation above,
2 moles of Fe2O3 reacted to produce 3 moles of CO2.
Therefore, Xmol of Fe2O3 will react to produce 10.23 moles of CO2 i.e
Xmol of Fe2O3 = (2x10.23)/3
Xmol of Fe2O3 = 6.82 moles
Therefore, 6.82 moles of Fe2O3 is required.
I really don’t know. Sorry
<u>125</u> is the total number of neutrons in an atom of 207/82 Pb
207 - 82 = 125
207 represents the mass number of the atom while 87 represent the atomic number. The mass number is usually the sum of the protons and neutrons in the nucleus.
Explanation:
Atoms of elements are usually classified by their proton number. A change in the proton number changes the element. However, the neutron number of an element can differ within a small range giving various isotopes of the element. Some will be stable others will be less stable. The less stable are less common to occur naturally because they decay.
Usually, for smaller atoms, the number of neutrons is more or less similar to the number of protons. However, with larger atoms, there are more neutrons than protons.
