Photosynthesis reactions in green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis. Determine the mass of glucose (C6H1206) produced
Answer: 60.0 g of glucose
Explanation:
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]
a) moles of [tex]CO_2[/tex]
[tex]\text{Number of moles}=\frac{88.0g}{44g/mol}=2.0moles[/tex]
b) moles of [tex]H_2O[/tex]
[tex]\text{Number of moles}=\frac{64.0g}{18g/mol}=3.5moles[/tex]
[tex]6CO_2+6H_2O\rightarrow C_{6}H_{12}O_6+6O_2[/tex]
According to stoichiometry :
6 moles of [tex]CO_2[/tex] require = 6 moles of [tex]H_2O[/tex]
Thus 2.0 moles of [tex]CO_2[/tex] require=[tex]\frac{6}{6}\times 2.0=2.0moles[/tex] of [tex]H_2O[/tex]
Thus [tex]CO_2[/tex] is the limiting reagent as it limits the formation of product.
As 6 moles of [tex]CO_2[/tex] give = 1 moles of glucose
Thus 2.0 moles of [tex]CO_2[/tex] give =[tex]\frac{1}{6}\times 2.0=0.33moles[/tex] of glucose
Mass of glucose = [tex]moles\times {\text {Molar mass}}=0.33moles\times 180g/mol=60g[/tex]
Thus 60.0 g of glucose will be produced from 88.0 g of carbon dioxide and 64.0 g of water
In green plants use carbon dioxide and water to produce glucose (C6H12O6) and oxygen. A plant has 88.0 g of carbon dioxide and 64.0 g of water available for photosynthesis produces 60.0 g of glucose.
To calculate the moles, we use the equation:
Number of moles Given mass Molar mass a) moles ofNumber of moles = (88.0g)/(44g / mol) = 2.0mol*epsilonb) moles of H2ONumber of les = (64.0g)/(18g / mol) = 3.5molesAccording to stoichiometry6 moles of re = 6mol of H2OWhat is mole fraction ?Mole fraction is a unit of concentration, described to be same to the range of moles of a element divided via way of means of the entire range of moles of a solution.
Thus it is well explained.

According to an energy pyramid model, which trophic level is expected have the largest biomass in land ecosystems ?
Answer:
According to an energy pyramid model, Producer is expected have the largest biomass in land ecosystems
Explanation:
In a trophic level, the producers possess the largest biomass. With the increasing trophic level, the biomass reduces. Hence, the producers at the base have high biomass.
On terrestrial ecosystem, the producers are the plants and trees and hence the greatest biomass exists in the plants and trees.
Hence, in an energy pyramid model, Producer is expected have the largest biomass in land ecosystems

A gas occupies 5.31 liters at a pressure of 0.55 atm. Determine the volume at standard pressure.
A. 2.92
B. 8.28L
C. 3.54 L
D. 9.65L
Answer:
Option A; V = 2.92 L
Explanation:
If we assume a lot of things, like:
The gas is an ideal gas.
The temperature is constant.
The gas does not interchange mass with the environment.
Then we have the relation:
P*V = n*R*T = constant.
Where:
P = pressure
V = volume
n = number of moles
R = constant of the ideal gas
T = temperature.
We know that when P = 0.55 atm, the volume is 5.31 L
Then:
(0.55 atm)*(5.31 L) = constant
Now, when the gas is at standard pressure ( P = 1 atm)
We still have the relation:
P*V = constant = (0.55 atm)*(5.31 L)
(1 atm)*V = (0.55 atm)*(5.31 L)
Now we only need to solve this for V.
V = (0.55 atm/ 1 atm)*(5.31 L) = 2.92 L
V = 2.92 L
Then the correct option is A.

(a) the same total mass as the reactants
(b)the same number of molecules as the reactants
(c) less mass than the reactants
(d) a greater number of molecules than the reactants
Answer:

Explanation:
as the law of conservation of matter (mass) states: matter can not be created nor destroyed but can transform from a form to another.
since the conversion of mass to energy can not be done except in nuclear reactions via (E= mc2). normal chemical equations must be balanced to achieve the law.

In the image below, light is displayed as particles called photons. Research to find out what photons are and then explain in your own words why they can be useful for modeling light.
Answer:
A photons is a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass.
Explanation:
Light consists of packets of energy (photons) that can only interact with the atoms and molecules of matter by being absorbed or emitted in discrete units. ... Photons carry momentum and energy like particles, but they also have a frequency and a wavelength like a sinusoidal wave. Thanks to photons we know that all quantum particles have both the properties of waves and particles. I hope it helps✌️

The temperature of water decreases on the dissolution of NH4NO3. From this observation, we can conclude that the solution process would be best described asa)exothermic with a positive entropy change.b)exothermic with a negative entropy change.c)endothermic with a negative entropy change.d)endothermic with a positive entropy change.e)exothermic with a negative free energy change
Answer: d)endothermic with a positive entropy change
Explanation:
Endothermic reactions are those in which heat is absorbed by the system and exothermic reactions are those in which heat is released by the system.
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
As temperature of water decreases on dissolution of [tex]NH_4NO_3[/tex] , it means heat has been absorbed by [tex]NH_4NO_3[/tex] during dissolution and that heat is taken from water. Thus process is endothermic. As dissolution will lead in the formation of ions [tex]NH_4^+[/tex] and [tex]NO_3^-[/tex] , randomness will increase and thus there is a positive entropy change.

In an extraction experiment similar to your expt. 4, you attempt to separate 2-naphthol from cyclohexane, both of which are dissolved in ether. You attempt the separation by extracting the organic layer with a Ì´5% NaOH (aq) solution (made by adding 5.00 g of NaOH to every 100 mL of water). Assuming that all of the base present in the aqueous solution reacts with the phenol during your extractions, what is the minimum volume of the aqueous NaOH solution needed to deprotonate 20.0 g of 2-naphthol in order to extract it into the water layer? Clearly show all calculations. After removal of the phenol from the ether layer, only cyclohexane would remain. Concisely explain how you could efficiently isolate relatively pure cyclohexane from the ether layer.
Answer:
[a]. 108 mL.
[b].
1. use HCL in washing for the neutralization of NaOH.
2. Wash with water.
3. make use of MgSO4 to remove water traces.
4. Evaporate to get the pure cyclohexane
Explanation:
The chemical equation for the reaction between 2-naphthol and Sodium hydroxide is given below as:
C₁₀H₈O + NaOH --------------------------------------------------> C10H7O⁻ Na⁺ + H₂O.
The C10H7O⁻ Na⁺ is the aqueous phase.
The molarity of Sodium Hydroxide is = [ (mass of sodium hydroxide ) ÷ molar mass sodium hydroxide × volume] × 1000.
The molarity of sodium hydroxide = [ (5/40) × 100] × 1000 = 1.25 M.
The number of moles of 2-naphthol = mass / molar mass = 20 / 144.17 = 0.138 moles.
Recall that, the formula for the number of moles = concentration × volume. Therefore, the volume of sodium hydroxide is given below as:
Volume of sodium hydroxide = the number of moles of sodium hydroxide ÷ concentration of sodium hydroxide = 0.138 ÷ 1.25 = 0.108L = 108 mL.
In order to efficiently isolate relatively pure cyclohexane from the ether layer, the following process must be followed:
1. use HCL in washing for the neutralization of NaOH.
2. Wash with water.
3. make use of MgSO4 to remove water traces.
4. Evaporate to get the pure cyclohexane

Explanation:
The task in this question is to match the right procedure to its purpose. It explains the procedure for the preparation of Fischer Esterification. Fischer Esterification Mechanism should incorporate the ceaseless expulsion of water from the framework or the use of a huge amount of excess alcohol since the general reaction is reversible. Fischer Esterification act as an organic reaction that is utilized to change over carboxylic acids within the sight of excess alcohol and a solid corrosive catalyst (acid) to give an ester as the eventual outcome.
