No of moles of Carbon, C = mass/ molar mass.
Molar mass of carbon = 12.0107. We only have to calculate the no of moles
of carbon to obtain carbon's mass. .
From Sucrose chemical formula C12H22O11 we know that there are 12
carbon atoms.
So there are 1.4x10^(20) x12 = 16.8 x 10^20 carbon atoms.
We will use avogardo's number to find out the number of carbon molecules
in the compound.
From Avogadro's no. One mole of any substance equals to 6.022140857
atoms.
So X mole contains 16.8 * 10^(20) carbon atom
(16.8x10^20 carbon atoms)/6.022 x10^23 particles/mol = 0.00279 mols
The molar mass of carbon is 12.0107g/mol so we'll multiply to get the mass:
0.00279 mols x 12 = 0.03348.
Below is an attachment of the Lewis structure with the lowest formal charges.
The formal charge is the fictitious charge that an atom in a molecule would have if the electrons in the bonds were evenly distributed among the atoms. The nonbonding electrons on a neutral atom are subtracted from its valence electron count, which is then followed by the number of bonds that bind it to other atoms in the Lewis structure, to get the formal charge. This is another way to put it. When hyponitrous acid is oxidized in the atmosphere, nitric and nitrous acids are produced. By reducing a nitrate or nitrite by sodium amalgam in the presence of water, hyponitrite salts have been created.

1) Left up: a chemical change. We can see new substance (red-blue) is formed from one blue and one red atom.
In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
2) Left down: a chemical change. We can see new substance (red-blue) is formed from two blue and one red atoms.
3) MIddle: a physical change. There is no new substance. Bonds are not broken.
4) Right up: a chemical change. Bonds are broken.
5) Right down: a physical change. Change of state of matter.
In neutralisation reactions, acid and base reacts. Acid dissociates to give out H⁺ ions and bases dissociate to give out OH⁻ ions. These H⁺ ions and OH⁻ ions react to form H₂O molecules.
and the anion from the acid dissociation and cation from base dissociation form salts.
therefore in a neutralisation reaction acid reacts with base to form water and the corresponding salt
Mg(OH)₂ + 2HNO₃ ---> Mg(NO₃)₂ + 2H₂O
HCl + NaOH ---> NaCl + H₂O
Hydrocarbons that lack π bond are called saturated hydrocarbons or alkanes
<h3>Hydrocarbons</h3>
- Hydrocarbon is an organic compound consisting of hydrogen and carbon.
- Hydrocarbons is an examples of 14 group hydrides.
- Hydrocarbons are colorless and hydrophobic.
- Their odors are usually like gasoline or lighter fluid.
- In oil and gas industry, the hydrocarbon in term, combines petroleum and natural gas they are the two naturally occurring phases of hydrocarbon.
<h3>Alkanes</h3>
- Alkanes also konwn as parafins
- They are called as saturated hydrocarbons
- Alkanes contain hydrogen and carbons arranged in tree structure
- Alkanes have two main sources petroleum and natural gas.
Therefore, Hydrocarbons that lack π bond are called saturated hydrocarbons
