Answer :
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Explanation :
Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.
For example : Methane, Ethane, etc.
Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds.
For example : Ethene, Butyne, etc.
Therefore, the saturated and unsaturated hydrocarbons are:
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Answer:
53.2
Explanation:
The balanced reaction is:
2Fe(s) + 3O₂(g) → Fe₂O₃
It means that 3 moles of oxygen form 1 mol of iron(III) oxide. The molar masses are: Fe = 55.8 g/mol and O = 16 g/mol. So
O₂ = 2x 16 = 32 g/mol
Fe₂O₃ = 2x55.8 + 3x16 = 159.6 g/mol
So, 32 g of O₂ corresponds to 1 mol of O₂. The stoichiometry calculus must be (always in moles):
3 mol of O₂ ------------------------ 1 mol of Fe₂O₃
1 mol of O₂ ------------------------ x
By a direct simple three rule:
3x = 1
x = 1/3 mol of Fe₂O₃
The mass is the molar mass multiplied by the number of moles, so:
m = 159.6x (1/3)
m = 53.2 g iron (III) oxide.
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near itshydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.
