The number of repetition of the Beta oxidation requires to fully convert 18 carbon activated fatty acid to Acetyl COA molecule is NINE.
Beta oxidation of fatty acid involves oxidative removal of successive two carbon units in the form of acetlyl COA, starting from the carboxyl end of the fatty acyl chain. Thus, a fatty acid which has 18 carbons will have to undergo nine repetition of beta oxidation before it is reduced to an acetyl COA.
Answer is: B. designing an experiment to test the plum pudding model.
Rutherford demonstrate that J.J Thompson's Plum Pudding model was not accurate, but before testing, he thought that plum pudding model is correct.
Rutherford theorized that atoms have their charge concentrated in a very small nucleus.
This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model, because it shows that most of the atom is empty space.
Answer:
The naswer to your question is Scandium
Explanation:
43 means the atomic mass is normally presented as a power
21 means atomic number is always a subscript
₂₁ ? ⁴³
Technetium ₄₃Tc⁹⁸
Scandium ₂₁Sc⁴⁴
Titanium ₂₁Ti⁴⁷
Cobalt ₂₇Co⁵⁹
Answer:
In He2 molecule,
Atomic orbitals available for making Molecular Orbitals are 1s from each Helium. And total number of electrons available are 4.
Molecular Orbitals thus formed are:€1s2€*1s2
It means 2 electrons are in bonding molecular orbitals and 2 are in antibonding molecular orbitals .
Bond Order =Electrons in bonding molecular orbitals - electrons in antibonding molecular orbitals /2
Bond Order =Nb-Na/2
Bond Order =2-2/2=0
Since the bond order is zero so that He2 molecule does not exist.
Explanation:
Answer:
Hg
Explanation:
We are given information about the unknown element, and using each characteristic, we can narrow down the possible elements until we have just one possibility left.
Conducts electricity: This means that the element has to be a metal, or a semi-metal, because non-metals cannot conduct electricity.
Forming chloride and oxide ions: When it is seen that it forms chloride and oxide ions in the form of XCl₂ and XO, it can be seen that this element has an ionic charge of +2. This narrows it down to the elements in <u>Group 2.</u>
Liquid at room temperature: This is tricky, because we realize that there are no elements in group 2 that are liquid at room temperature. So hence we can look at groups 3 to 12, and see if there are any liquid metals with an ionic charge of +2.
Taking all this information into account, we can see that the only element it can be is mercury (Hg).
