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?

Answers

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

Molecular orbital diagram for Fe.

Answers

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

A typical home instant pot has an internal volume of 6.5 Liters. If the steam inside an instant pot with an internal pressure of 191.0 kPa and a temperature of 750.0 K was released into the atmosphere at 101.3 kPa and 298K, what volume with the steam occupy in the atmosphere?

Answers

Answer: V2 = 4.8696 L is the volume occupied by the steam in the atmosphere

We can use the combined gas law to solve this problem.

Combined gas law: P1 V1 / T1 = P2 V2 / T2

(191.0 kPa)(6.5 L) / (750.0 K) = (101.3 kPa)(V2) / (298 K)

Now we solve for V2;

1241.5 / 750 = 101.3 / 298

Now we cross-multiply;

369967 = 75975x

Divide by 75975 on each side;

369967 / 75975 = 75975x / 75975

Round our answer to sig figs;

x (aka V2) = 4.8696 L is the volume occupied by the steam in the atmosphere

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 !​

Answers

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

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.

Answers

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
