Spheres of Earth Assignment Active Analyzing Sphere Interactions Explain how Earth's spheres may be affected by the droughts brought on by El Niño. Sometimes, the surface of the Pacific Ocean warms up, causing changes in the weather in some areas. This phenomenon is called El Niño. El Niño causes the amount of rainfall in some parts of the United States and South America to increase. It also causes droughts to occur in Southeast Asia and Australia. Droughts occur when an area receives less rain than it normally does over a certain period.

Molecular orbital diagram for Fe.
ANSWER;
1s22s22p63s23p63d64s2
EXPLANATION;
Molecular orbital diagram for Fe.
In writing the electron configuration for Iron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Iron go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. We now shift to the 4s orbital where we place the remaining two electrons. After the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d6.
Therefore the Iron electron configuration will be 1s22s22p63s23p64s23d6.
Note that when writing the electron configuration for an atom like Fe, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written
Therefore we have 1s22s22p63s23p63d64s2
4.which is a product of the process shown above?
a. carbon dioxide
b. sugar
c. sunlight
d. water
5.where does the energy that drives this process come from?
a. oxygen
b. sugar
c. sunlight
d. water
Answer:
4. b 5.C
Explanation:
Photosynthesis makes sugar for plants and sunlight is the energy used to convert CO2 and water into glucose
The product of the process of photosynthesis is sugar and the energy to dive the process of photosynthesis comes from sunlight.
What is photosynthesis?Photosynthesis is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

How many moles are in 3.4 x 10-7 grams of Silicon dioxide, SiO2?
Answer:
Number of moles = 0.057 × 10⁻⁷ mol
Explanation:
Given data:
Mass of SiO₂ = 3.4 × 10⁻⁷ g
Number of moles = ?
Solution:
Number of moles = mass/molar mass
Molar mass of SiO₂ = 60 g/mol
by putting values,
Number of moles = 3.4 × 10⁻⁷ g / 60 g/mol
Number of moles = 0.057 × 10⁻⁷ mol

Explanation:
The reason why it is important to prepare for an disaster is because Being prepared can reduce fear, anxiety, and losses that accompany disasters. People also can reduce the impact of disasters (flood proofing, elevating a home or moving a home out of one's harm's way, and securing items that could shake loose in an earthquake) and sometimes avoid the danger completely.

The balanced equation for the syntheis of Iron (I) oxide is below:
If 5.4 moles of Fe react with 4.7 moles of O2, what is the maximum amount of Fe2O3 (in moles) that can be produced? What is the limiting reactant?
a
3.1 moles of Fe2O3 is the maximum amount that can be produced. Oxygen is the limiting reactant.
b
2.7 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.
c
7.1 moles of Fe2O3 is the maximum amount that can be produced. Oxygen is the limiting reactant.
d
10.8 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.
Answer:
Option B. 2.7 moles of Fe2O3 is the maximum amount that can be produced. Iron is the limiting reactant.
Explanation:
The balanced equation for the reaction is given below:
4Fe + 3O2 —> 2Fe2O3
From the balanced equation above,
4 moles of Fe reacted with 3 moles of O2 to produce 2 moles of Fe2O3.
Next, we shall determine the limiting reactant. This can be obtained as follow:
From the balanced equation above,
4 moles of Fe reacted with 3 moles of O2.
Therefore, 5.4 moles of Fe will react with = (5.4 × 3)/4 = 4.05 moles of O2.
Thus, we can see that only 4.05 moles out of 4.7 moles of O2 given is needed to react completely with 5.4 moles Fe. Therefore, Fe is the limiting reactant and O2 is the excess reactant.
Finally, we shall determine the maximum amount of Fe2O3 produced from the reaction.
In this case, the limiting reactant will be use because it will produce the maximum amount of Fe2O3 as all of it is used up in the reaction.
The limiting reactant is Fe and the maximum amount of Fe2O3 produced can be obtained as follow:
From the balanced equation above,
4 moles of Fe reacted to produce 2 moles of Fe2O3.
Therefore, 5.4 moles of Fe will react to produce = (5.4 × 2)/4 = 2.7 moles of Fe2O3.
Summary:
Limiting reactant => iron (Fe)
Maximum amount of Fe2O3 produce = 2.7 moles

A saturated hydrocarbon having molecular formula CnH2n+2 diffuses through a porous membrane twice as fast as sulphur dioxide. Calculate the volume occupied by the hydrocarbon at27°C and 2atm ?
Help me fast !
Answer:
12.3 L
Explanation:
Now we have that the rate of diffusion of the saturated hydrocarbon is R1
Rate of diffusion of sulphur dioxide is R2
Molar mass of hydrocarbon is M1
Molar mass of sulphur dioxide is 64 gmol-1
From Graham's law;
R1/R2 = √64/M1
2/1 =√64/M1
(2/1)^2 = (√64/M1)^2
4/1 = 64/M1
4M1 =64
M1 = 16
To obtain the number of moles of the gas;
(n*12) + (2n + 2) 1 = 16
12n + 2n + 2 = 16
14n + 2 = 16
14n = 16 - 2
n = 14/14
n = 1
Hence the hydrocarbon is CH4
Volume occupied by CH4 at STP = 22.4 L
Hence;
P1 = 1 atm
T1 = 273 K
V1 = 22.4 L
T2 = 300 K
P2 = 2 atm
V2 = ?
P1V1/T1 = P2V2/T2
P1V1T2 = P2V2T1
V2 = P1V1T2/P2T1
V2 = 1 * 22.4 * 300/2 * 273
V2 = 12.3 L
The volume occupied by the hydrocarbon at 27 °C and 2 atm is 12.31 L
Let the hydrocarbon be initially at standard temperature and pressure (STP)
Thus, we can obtain the new volume of the hydrocarbon by using the combined gas equation as illustrated below:
Initial volume (V₁) = STP = 22.4 L Initial pressure (P₁) = STP = 1 atmInitial temperature (T₁) = STP = 273 KFinal temperature (T₂) = 27 °C = 27 + 273 = 300 KFinal pressure (P₂) = 2 atmFinal volume (V₂) =?P₁V₁ / T₁ = P₂V₂ / T₂
(1 × 22.4) / 273 = (2 × V₂) / 300
22.4 / 273 = (2 × V₂) / 300
Cross multiply
273 × 2 × V₂ = 22.4 × 300
546 × V₂ = 6720
Divide both side by 546
V₂ = 6720 / 546
V₂ = 12.31 L
Thus, the volume occupied by the hydrocarbon at 27 °C and 2 atm is 12.31 L
