Answer:
The correct answer is - 4-nitroaniline.
Explanation:
It is given that all three solid compounds salicylic acid + 4-nitroaniline + naphthalene are equal in the ratio in the mixture and then 1 gram of this mixture is dissolved in the diethyl ether and run a drop of the solution on TLC plate. This plate shows three spots.
The salicylic acid and naphthalene would stay dissolved in the diethyl ether solution due to the 4-nitroaniline could be extracted by adding aqueous acid and involve in the aqueous layer and thus spot of 4-nitroaniline would be with largest Rf value.
Answer:
There are 8Si atoms and 16 O atoms per unit cell
Explanation:
From the question we are told that:
Edge length 
Density 
Generally the equation for Volume is mathematically given by
Where
Molar mass of (SiO2) for one formula unit
Therefore
Density of Si per unit length is
Molar mass of (SiO2) for one formula unit
Therefore
There are 8Si atoms and 16 O atoms per unit cell
A wave.
Scientists now recognize that light can behave as both a particle and a wave.
The one that has a higher entropy for the reaction is products.
<h3>What is entropy?</h3>
Entropy is a measureable physical characteristic and a scientific notion that is frequently connected to a condition of disorder, unpredictability, or uncertainty. It is the measurement of the amount of thermal energy per unit of temperature in a system that cannot be used for productive work. It is a measure of a system's molecular disorder or unpredictability since work is produced by organized molecular motion.
It should bm be noted that the entropy of gas is more than entropy of aqueous which is more than the entropy of liquid and the entropy of solid.
On the product side there are more gas than the reactant side. Therefore, product has more entropy.

Step 1-Light Dependent
CO2 and H2O enter the leaf
Step 2- Light Dependent
Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2
Step 3- Light Dependent
The electrons move down to enzymes
Step 4-Light Dependent
Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-Light independent
The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.
Step 6-Light independent
The calvin cycle converts 3CO2 molecules from the atmosphere to glucose
calvin cycle
The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
