The charge of a nucleus is positive
Answer:
a. chain length and degree of saturation.
Explanation:
Fatty acids can be classified according to the length of their chain, for example, in short (if it has less than 8 carbons), medium (between 8-12 carbons), long (between 12-18 carbons) and very long (if it has less than 18 carbons); they are also classified according to their degree of unsaturation, in saturated, monounsaturated and polyunsaturated; and according to the isomerism in cis and trans fatty acids.
Answer:
Proton = 119
Electron = 119
Neutron = 183
Explanation:
Mass number (A) = 302
Atomic number (Z) = 119
Proton = atomic number = 119
Since there is no charge on the element, it means the element is neutral.
Therefore,
Electron = proton = 119
Mass number = proton + Neutron
Neutron = Mass number — proton
Neutron = 302 — 119
Neutron = 183
The percentage of calcium phosphate in ore = 55. 9% so it means each 100g of ore contains 55.9 g of calcium phosphate
The formula of calcium phosphate = Ca3(PO4)3
As per molecular formula each mole of calcium phosphate contains three moles of phosphorous
mass of each mole of calcium phosphate = 310 g
for 31 g of P we need = 310 /3 g of calcium phosphate
= 103.33 g of calcium phosphate
for 1 g of P we need = 103.33 / 31 g of calcium phosphate = 3.33 g
So for 1000g of P we need = 3.33 X 1000g of calcium phosphate
= 3333.3 g of calcium phosphate
now for 55.9 g of Calcium phosphate we need = 100 g of ore
so for 3333.3 g of calcium phosphate we need = 100 X 3333.3 / 55.9 g
= 5963.03
Quantum states of electrons are usually written in terms of four numbers: the principle quantum number (n), the angular momentum azimuthal number (L), the magnetic quantum number (ml), and the spin projection number (ms). The quantum number set (4,1,0,+1/2) and (4,1,1,+1/2) share the same principle quantum numbers and therefore both sit in the n=4 electron shell.
