When we show the structure of a molecule, we see the arrangement of atoms in the molecule.
<h3>Structure of molecules</h3>
The structure of a molecule shows the arrangement of atoms in the molecule.
1) There are 24 carbon atoms in the molecule.
2) There are 30 p- orbitals that are involved in pi bonds in the molecule.
3) We need to add 22 lone pairs of electrons
4) We do not need to add any formal positive charge to the molecule.

Answer:
warm, dry downslope wind affecting Southern California - Santa Ana wind
a seasonally changing wind- monsoon
wind blowing from a valley up a mountain slope - valley breeze
generated by cold thunderstorm downdrafts - haboob
Explanation:
The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.
Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.
Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.
Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.
Answer:
The answer to your question is 1 mol of Fe₂O₃
Explanation:
Data
mass of Fe = 112 g
mass of Fe₂O₃ = ?
Balanced chemical reaction
Fe₂O₃ + 3CO ⇒ 2Fe + 3CO₂
Process
1.- Calculate the molar mass of Fe₂O₃ and 2Fe
molar mass Fe₂O₃ = (56 x 2) + (16 x 3) = 160 g
molar mass of Fe = 56 x 2 = 112 g
2.- Use proportions to calculate the mass of Fe₂O₃ formed
160 g of Fe₂O₃ ----------------- 112 g of Fe
x ----------------- 112 g of Fe
x = (112 x 160)/112
x = 160 g of Fe₂O₃
3.- Calculate the moles of Fe₂O₃
160 g of Fe₂O₃ ------------------ 1 mol
160 g of Fe₂O₃ ------------------ x
x = (160 x 1)/160
x = 1 mol of Fe₂O₃
Explanation:
Opposite hemispheres have opposite seasons, no matter the earth's rotation, because of the earth's tilt. The earth's tilt is responsible for all seasons.
