Which of the following statements best describes why carbon can form a variety of organic compounds? Carbon atoms bond readily w
olga_2 [115]
Answer:
            <span>Carbon readily forms covalent bonds with other carbon atoms.

Explanation:
                   As we know approximately more than 95 % compounds, either isolated, discovered or synthesized belongs to organic compounds containing carbon atoms.
                  This great diversity of organic compounds is due to following facts.

1) Catenation:
                      Carbon has a peculiar behavior of self linkage. This self linkage of one carbon with another is called as catenation. In this way carbon can form a long chain of carbon atom. A branching can also take place when one carbon is bonded further to three of four carbon atoms.

2) Isomerism:
                     Secondly the carbon containing compounds show isomerism. In which molecular formula is same but structural formula is different. For example molecular formula C</span>₅H₁₂ can make following compounds,

                                a)  n-Pentane

                                b)  2-Methylbutane

                                c)  2,2-Dimethylpropane

3) Multiple Bonds:
                            Carbon can form multiple bonds i.e double bond like in alkenes and triple bonds like in alkyne. 

Due to these factors carbon gets very high number of opportunities to form large number of compounds.

Which solution will form a precipitate when mixed with a solution of aqueous na2co3? which solution will form a precipitate when
trapecia [35]

Answer:

CuCl_{2}(aq.) will form a precipitate of insoluble CuCO_{3} when aqueous Na_{2}CO_{3} is added.

Explanation:

According to solubility rule-

all carbonates are insoluble except group IA compounds and NH_{4}^{+}

all salts of sodium are soluble

When Na_{2}CO_{3} is added to given solutions, a double displacement reaction takes place in each solution to form a sodium salt and a carbonate salt.

So, in accordance with solubility rule, addition of Na_{2}CO_{3} into CuCl_{2}(aq.) will result precipitation of insoluble CuCO_{3}

Reaction: Na_{2}CO_{3}(aq.)+CuCl_{2}(aq.)\rightarrow 2NaCl(aq.)+CuCO_{3}(aq.)
