Directions:Convert the following word equation into formula equations by changing element and compound names into chemical formulas. 1.Sodium+oxygen > sodium oxide

2.Copper+silver nitrate > copper(II)nitrate+silver

3.Aluminum chlorate+barium sulfate > aluminum sulfate+barium chlorate

4.Bromine+calcium iodide > calcium bromide+iodine

5.Zinc sulfide+magnesium arsenate > zinc arsenate+magnesium sulfide

6. Cobalt+lead(II) nitrate > cobalt(III)nitrite+lead

7.Potassium+water > potassium hydroxide+hydrogen

8.Lithium hydroxide+hydrogen acetate > lithium acetate+water

9.Ammonium chloride+nickel(II) chromate > ammonium chromate+ nickel(II) chloride

10.Phosphorus+oxygen > tetra-phosphorus decaoxide

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

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.
