In the electron cloud model, electrons are said to be moving so fast that a person can _____.

Answers

Answer 1
Answer:

Answer: Not determine their exact position.

Explanation:  In the electron cloud model, electrons are said to be moving so fast that a person cannot determine their exact position.

This phenomenon goes well off with the Heisnberg Uncertainity Principle (HUP)which states that the momentum (Δm) and position (Δx) of an obejct cannot be determined simultaneously at the same time.

The mathematical relation of HUP is -

                                      Δx Δm ≥ h/ 4π

where h = Planck's Constant
Answer 2
Answer: cannot describe their exact position.

At the end of β-oxidation all carbons of a fatty acid are released in the form of

Answers

Answer:

ACETYL-CoA, FADH

2  NADH  

 acetyl-CoA

Explanation: Beta oxidation of carbons of fatty acid acid molecules leads to the formation Acetyl-CoA, FADH and NADH.

The overall reaction for the process

Cn-acyl-CoA + FAD + NAD+

+ H

2O + CoA → Cn-2-acyl-CoA + FADH

2 + NADH + H+

+ acetyl-CoA.

formula of NADH is C21H27N7O14P2

formula of FADH is ‎C27H35N9O15P2.

Both NADH(Nicotinamide adenine dinucleotide) and FADH( Flavin adenine dinucleotide) are

formular for Acetyl CoA IS C23H38N7O17P3S.

Beta oxidation is a breakdown process taking place in living systems which catabolises the fatty acids through glycolysis or fermentation leading to the release of Acetyl CoA, NADH AND FADH2.

Answers

Answer:

1. The evidence that chemical reaction has occurred can be found in the change of the reagents present after the reaction, that is formation of glucose in the area where the reaction is taking place

2. The most abundant element of the chemical reaction is oxygen which has a total quantity of 18 atoms in the reaction

3. The oxygen atom has an atomic number of 8 and therefore contains 8 protons and 8 neutrons and (therefore) 8 electrons (to be neutral, electronically)

4. The protons and the neutrons of the atom, oxygen, are located in the nucleus, while the electron are found in the different orbitals surrounding the atom

5. The element, oxygen, symbol, O, belongs to the group 16 of period 2 in the periodic table

Within a particular compound, an atom gives up two electrons. This atom is A. part of a covalent compound.
B. positively charged.
C. negatively charged.
D. not part of an electrolyte.

Answers

Answer:

The correct answer is option B. positively charged.

Explanation:

A positively charged ion is an atom that readily loses its one or more electrons in a compound. Positively charged ion generally has same number of electrons and protons which means they are neutral charge atom. These atoms are generally attracted to negatively charged ion that lack electron in outer shell.

Thus, the correct answer is option. B. positively charged.
It is a positively charges because when an atom gives up electrons it becomes positively charges. Think of it like this.....its being generous so it deserves to be a positive person. ;D. 
It cant be A. because a covalent bond only shares and doesn't give up electrons. Our answer must be an ion.
Its not negatively charged because it didn't gain any.

So our answer is B. positively charged
