What is spectrophotometry? It is an analytic method that it use substances light absorbance property
How can this be useful in identifying drugs? It possible compare spectra and identify problem substance
Explanation:
The way substances absorb light is unique and because of that it is possible to use spectrophotometry for substances identifying. the model spectra are measured in ideal conditions, so, it is difficult ensure the same conditions and to achieve identical spectra.
The correct answer is :'The gravitational force between two objects is related mathematically to their mass and the distance between them'.
Explanation:
A scientific law is a statement which explains physical phenomena and has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations after each conduct.
A scientific law comes into picture after the acceptance of a theory which explains or exposes the reason behind any physical phenomena occurrence.
So the best example of scientific law:
The gravitational force between two objects is related mathematically to their mass and the distance between them.
If another hydrogen of c2h5cl is replaced by a chlorine atom to yield c2h4cl2, it would result in one isomer.
In contrast to 1,2-dichloroethane, which has two chlorine atoms connected to distinct carbon atoms, 1,1-dichloroethane has two chlorine atoms bound to the same carbon atom.
Isomers are each of two or more compounds having the same formula but various atom arrangements in the molecule and unique characteristics.
<h3>What three types of isomers are there?</h3>
Chain isomers
Functional group isomers
Positional isomers
These are the three different categories of structural isomers.
<h3>How is an isomer recognized?</h3>
Their bonding patterns and the way they occupy three-dimensional space can be used to distinguish them.
Determine the bonding patterns of structural (constitutional) isomers.
Although the atoms in the compounds are the same, their connections create various functional groups.
<h3>What makes isomers significant?</h3>
Because two isomers might have the same chemical formula but different chemical structures, they are significant.
The molecule's properties are influenced by its structure.
The formula to calculate osmotic pressure is Osmotic Pressure = M R T M = Molarity R = Ideal Gas Constant T = Temperature in Kelvin
So, 24.6/.2254kg=109.139g /kg >>>>> Molarity 109.139 x mols/92 g = 1.186 mols kg^-1 1.186 x 0.08134 x 298 K = 28.755 atm <span>1.06852 x 0.08134 x 298K= 26.5 atm
