The barometer reading is 698. mm Hg. Following the steps on pages 1 to 3, complete this table of data. Volume of H_(2) Gas Generated (mL) square
What colorless odorless, poisonous gas is a by-product of gasoline engines? A carbon disulfide B carbon monoxide C hydrogen oxide D hydrogen sulfide
The prefix for a hydrocarbon with 6 carbons is __ but- hex- pent- hept-
5. Solvents such as alcohols, acetones, methyl ethyl ketone, and petroleum based solvents are all examples of A. ignitable wastes B. radioactive wastes C. recyclable wastes D. bioaccumulative wastes
Continue to shake until no more salt will come out of the shaker. What happens to the last several crystals of salt that come out? The sodium ions dissolve while the chloride ions sink to the bottom. The salt crystals react with the water to form a new compound. All of the ions separate from each other and dissolve into the water. The salt crystals don't dissolve in the water and fall to the bottom unchanged.
Hydrogen sulfide is: A) Odorless B) Colorless C) Not flammable D) Red in color
