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

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
