Carbon tetrachloride may be produced via the reaction between methane and chlorine gases: """ch4 (g) + 4 cl2 (g) => ccl4 (l) + 4 hcl (g)"""
if this reaction generates 2.50 gallons of ccl4, how many pounds (lbs) of hcl were also generated? the
density of ccl4 is 1.5867 g/ml.

i do not know how to approach this question because it features 4 different types of units:
an explanation would be appreaciated

Express the following number in scientific notation. 0.026890 =

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.

2-bromo-2-methylbutane undergoes an e1 elimination reaction in the presence of ethanol. in the next reaction only one of the possible products is represented. although the product shown is not the major product of the reaction, notice that there is more than one way it can be produced. complete the mechanism and draw the missing substances.
