<u>Answer:</u>
1. In Glucose: C : H : O = 1 : 2 : 1
2. In Sulfuric acid: H : S : O = 2 : 1 : 4
3. In Butene: C : H = 1 : 2
<u>Explanation:</u>
Mole ratio is defined as the ratio of amounts in moles present in a compound. Simplest mole ratio basically means that the moles are present in the least whole number ratio.
- In Glucose,
Moles of Carbon atom = 6
Moles of Hydrogen atom = 12
Moles of Oxygen atom = 6
Mole ratio of the atoms: C : H : O :: 6 : 12 : 6
Making this, the simplest mole ratio C : H : O = 1 : 2 : 1
- In Sulfuric acid,
Moles of Sulfur atom = 1
Moles of Hydrogen atom = 2
Moles of Oxygen atom = 4
Mole ratio of the atoms: H : S : O = 2 : 1 : 4
- In Butene,
Moles of Carbon atom = 4
Moles of Hydrogen atom = 8
Mole ratio of the atoms: C : H = 1 : 2
<span>Answer:
.01 moles of D to .005 moles of L ~ so, .01+.005 = .015 total; using this total value, divide the portions of D and L.
so .01/.015 to .005/.015 ~ 67% D to 33% L.
And thus, the enantiomer excess will be 34%.</span>
Answer:2.86x10^-7m
Explanation:E=hc/^
E=6.94x10^-19J
c = 2.9979x10^8m/s
h= 6.626x10^-34Js
^ =( 6.626x10^-34)x( 2.9979x 10^8)/ 6.94x10^-19
= 2.86x10^-7m
Answer: He did not discuss about any of these.
Explanation: Dalton proposed some of the postulates for his atomic theory. They are:
1) Matter is made up of atoms which are not divisible.
2) Atoms of different elements combine in a fixed ratio to form compounds.
3) The atomic properties of given element are same including mass. This states that all the atoms of an element have same mass but the atoms of different elements have different masses.
4) No atoms are either created or destroyed during a chemical reaction.
5) Atoms of an element are identical in mass, size and other chemical and physical properties.
As it is visible from the postulates, he only discussed only about the atoms but not subatomic particles or isotopes.
Answer:
Answer is explained below.
Explanation:
As (+) menthol and (-) menthol are enantiomers whose physical properties are same except optical activity so we can expect they have similar Rf values.
Whereas diastereomers have different physical properties and different Rf values.
For example when the (+) menthol , (-) menthol, isomenthol and neomenthol undergo TLC (thin layer chromatography) the
Rf values of.(+menthol) = .447
Rf (+isomenthol) = .395
Rf (+neomenthol)= .487
Rf (-menthol) = .434
The above data shows that (+) menthol and (-) menthol have almost same Rf values and vary a little i.e 0.447 and 0.437. So we can conclude them as enantiomers
Whereas (+) menthol or (+) neomenthol or (+) isomenthol i.e 0.447 , 0.395 and 0.487 have different Rf values. We can conclude them as diasteromers.
(+) menthol and (-) menthol - enantiomers
(+) menthol and (+) neomenthol- diastereomers
(-) menthol and (+) isomenthol - diastereomers
