C4H10+02--->H20+C02 calculate the number of grams c4h10 needs to produce 5.12 moles of co2 (balance equation and solve using factor label method)

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)
