Answer:
The right choice is CHCl₃
Explanation:
- <u>To find the empirical formula firstly, change the mass to moles.</u>
For Carbon :
no. of moles = (mass / molar mass) = (5.03 g / 12 g/mol )= 0.42 mol
<u><em>For Hydrogen :</em></u>
no. of moles = (mass / molar mass) = (0.42 g / 1 g/mol )= 0.42 mol
<u><em>For Chlorine :</em></u>
no. of moles = (mass / molar mass) = (44.5 g / 35.5 g/mol )= 1.25 mol
The ratio for Carbon and Hydrogen is 1 : 1
0.42 mol / 042 mol =1.00
- <u>
Then find a ratio between the moles.
</u>
The ratio of Chlorine to both Carbon and Hydrogen is 3:1
1.25 mol / 0.42 mol = 2.98 ≅ 3
So the ratio is 1 C : 1 H : 3 Cl.
So, the right choice is CHCl₃
Carbon usually forms four bonds one to Hydrogen and 3 to Chlorine atoms.
Chlorine usually forms one bond to Carbon atom.
Hydrogen usually forms one bond Carbon atom.
We first determine the complete reaction of the substances given above to tell whether precipitates are formed.
NaCl + NaBr = no reaction
NaCl + Na2CO3 = no reaction
<span>NaCl + BaCl2 = no reaction</span>
<span>NaCl + HCl = no reaction
</span>
From all the substances given, reaction cannot happen therefore no precipitates are formed.
Answer : The hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.
Explanation :
As the organic compounds are classified into two categories that is acyclic (aliphatic) and cyclic (aromatic) compounds.
Acyclic compounds : It is an open chain compound with linear structure.
Cyclic compounds : It is a closed chain compound having a carbon ring structure.
Hydrocarbon : It is an organic compound that contains only hydrogen and the carbon atoms. They are of two types which are saturated hydrocarbon and unsaturated hydrocarbon.
Saturated hydrocarbon : These are the compounds which containing single bonds between the carbon-carbon atoms. In saturated compounds, there are more number of hydrogen bonded with the carbon atom.
Unsaturated hydrocarbon : These are the compounds which containing double and triple bonds between the carbon-carbon atoms. In unsaturated compounds, there are less number of hydrogen bonded with the carbon atom.
Hence, the hydrocarbons containing a saturated carbon ring are called Aliphatic cyclic hydrocarbon.
Then it would become: S2-
Its charge will be -2.
