The main cause of rising the surface temperature of the pacific ocean drought in the western united states, and flooding on the pacific coast of south america is the phenomenon called El-nino.
Surface temperatures in the equatorial Pacific rise during El Nino, while the east-west trade winds that blow close to the equator diminish. Typically, trade winds from the Americas move eastward towards Asia.
They sputter and alter course because of El Nino, becoming westerlies and carrying warm water from the western Pacific to the Americas.
Deeper seas are typically nutrient-richer, however under El Nino upwelling is limited, which reduces phytoplankton along the coast. Deeper waters typically rise to the surface.
Fish that consume phytoplankton are the first to be impacted, then organisms farther up the food chain. Additionally, tropical animals are transported by warmer water to colder regions, upsetting numerous ecosystems.

What is the cause of rising surface temperatures of the pacific ocean, drought in the western united states, and flooding on the pacific coast of south america?
The cause of rising surface temperatures of the pacific ocean, drought in the western united states, and flooding on the pacific coast of south America is the carbon – producing companies.
The stoichiometric coefficient for aluminum, Al when the chemical equation is balanced is 2.
To obtain the stoichiometric coefficient for aluminum, we shall write and balance the equation for the reaction. This is illustrated below:
Aluminum => Al
Iron (II) chloride => FeCl₂
Aluminum chloride => AlCl₃
Iron => Fe
Aluminum + Iron (II) chloride —> Aluminum chloride + Iron
Al + FeCl₂ –> AlCl₃ + Fe
There are 3 atoms of Cl on the right side and 2 atoms on the left side. It can be balance by writing 3 before FeCl₂ and 2 before AlCl₃ as shown below:
Al + 3FeCl₂ –> 2AlCl₃ + Fe
There are 2 atoms of Al on the right side and 1 atom on the left. It can be balance by writing 2 before Al as shown below:
2Al + 3FeCl₂ –> 2AlCl₃ + Fe
There are 3 atoms of Fe on the left side and 1 atom on the right side. It can be balance by writing 3 before Fe as shown below:
2Al + 3FeCl₂ –> 2AlCl₃ + 3Fe
Now, the equation is balanced.
The coefficient of Aluminum, Al in the balanced equation is 2.

Answer:
2.
Explanation:
2Al(s) + 3FeCl₂(aq) → 2AlCl₃(aq) + 3Fe(s).
It is clear that 2 mol of Al react with 3 mol of FeCl₂ to produce 2 mol of AlCl₃ and 3 mol of Fe.

Answer : The percent yield of is, 68.4 %
Solution : Given,
Mass of = 0.16 g
Mass of = 0.84 g
Molar mass of = 16 g/mole
Molar mass of = 32 g/mole
Molar mass of = 44 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 mole of react with 1 mole of
So, 0.026 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Now we have to calculate the moles of
From the reaction, we conclude that
As, 2 mole of react to give 1 mole of
So, 0.026 moles of react to give moles of
Now we have to calculate the mass of
Theoretical yield of = 0.572 g
Experimental yield of = 0.391 g
Now we have to calculate the percent yield of
Therefore, the percent yield of is, 68.4 %
Plantations
Economies
Colonies
Cash Crops
Answer: cash crops
Explanation:
trust
Answer: Cash Crops
Explanation: These crops were used in the south to make loads of money before the civil war in southern plantations so they were known as cash crops
B) Water would be able to dissolve all ionic compounds.
C) Water would not expand when it freezes.
D) Water would not exist on Earth.
The hydrogen bond is a secondary bond formed between a hydrogen (attached to an highly electronegative element ,: F, O or N) and another atom of an highly electronegative element ,: F, O or N.
In case of water hydrogen bond helps water
a) to dissolve certain substances which can make hydrogen bond
b) it makes it liquid and room temperature unlike H2S which is a gas at room temperature due to absence of hydrogen bond
c) higher volume and low density of ice as compared to liquid water. Due to hydrogen bond ice forms open cage like structure which increases its volume and decreases its density. Thus water expands on freezing
So in absence of hydrogen bond Water would not expand when it freezes.
