Question

While studying chemical reactions and conservation of matter, Sarah's class conducted a variety of experiments. Sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. The students lit the candle and let it burn to completion. All that was left was wax and charred candle wick. Per their teacher's instructions, the students found the mass of the products. Their data can be seen in the data table. Formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter.

Answer 1

I really need help like asap,

Answer 2

What does the data table say

Answer 3

let me guess - the mass of the burned candle + wick didn't add up the original mass of the candle?

well, some of the mass of the candle was converted to CO2 (gas is matter, after all, and it doesn't just come from nowhere). so you'd have to set up an apparatus that will capture CO2. if you can account for that the masses should add up, barring any uncertainty in the measuring equipment.
