Answer:
Volume of lithium atom is found to be 1.47 X 10⁻²⁹ m³
Explanation:
Let us consider the volume of atom as a sphere (but it is little complex than that). This volume is mathematically expressed as,
----------------------------------------------------------------------------------------(Eq. 1)
Here, R is the radius of lithium atom. The radius is given in picometers, so firstly let us convert it into meters
placing this value in Eq.1 the required result is achieved
V= 1.47 X 10⁻²⁹ m³
Answer:
Groups of atoms that are added to carbon backbones and give them unique properties are known as <u>Functional Groups</u>.
Explanation:
In organic chemistry they are called as Functional Group because they are the active part of a molecule. These groups give a unique characteristic to molecule both chemically and physically. Also, each functional group represent a different class of compounds.
Examples:
S No. Functional Group Name
1 R--X Alkyl Halides
2 R--OH Alcohols
3 R--NH₂ Amines
4 R--O--R Ethers
5 R--CO--R Ketones
6 R--CO--H Aldehydes
7 R--CO--OH Carboxylic acids
8 R--CO--X Acid Halides
10 R--CO--NR₂ Acid Amides
11 R--CO-OR' Esters
Answer:
The correct statements are given below
Explanation:
b Enoyl CoA isomerase an enzyme that converts cis double bonds to trans double bonds in fatty acid metabolism,bypasses a step that reduces Q,resulting in the higher ATP yield.
c Even chain fatty acids are oxidized to acetyl CoA in the beta oxidation pathway.
f The final round of beta oxidation foe a 13 carbon saturated fatty acid yields acetyl CoA and propionyl CoA a three carbon fragment.
Answer:
Cl₂O₇
Explanation:
For the reaction:
ClₓOₙ + H₂ → HCl + H₂O
Moles of HCl and moles of H₂O are:
HCl: 0.233g HCl ₓ (1mol / 36.46g) = 6.39x10⁻³ mol HCl
H₂O: 0.403g H₂O ₓ (1mol / 18.02g) = 2.236x10⁻² mol H₂O
As you can see, moles of HCl are equivalent to moles of Cl in the compound and moles of H₂O are equivalent to moles of O in the compound, that means:
6.39x10⁻³ mol Cl
2.236x10⁻² mol O
Empirical formula is the simplest ratio of atoms presents in a molecule. If Cl is <em>1</em>, Oxygen will be:
2.236x10⁻² mol / 6.39x10⁻³ = <em>3.5</em>
As empirical formula must be given in natural numbers, the empirical formula is:
<em>Cl₂O₇</em>
<em></em>
