What would the name of a compound composed of nickel, sulfur, and oxygen be? a. nickel sulfur oxide b. nickel sulfate c. nickel oxygen sulfide d. none of these

The answer to your question is:  B. Nickel Sulfate

Explanation:

A. Nickel sulfur oxide  this compound do not exist, this option is incorrect.    

B. Nickel sulfate  This compund exist and the formula is NiSO₄

C. Nickel oxygen sulfide  This compound do not exist, the order of the names is inocrrect.

D. None of these This option is incorrect because because letter B is correct.

the answer is 1 i believe

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
