Question

Problem

when you go camping and have a fire to roast marshmallows,what happen to the wood at the end of the night? it burns and we call this a chemical change. however the next morning there's less material in the fire pit than the night before . what happen to all the wood???

the problem that I have is that in a chemical reaction, is the mass of the product equal to the mass of the reactants ?? what do you think??


hypothesis : ​

Answer 1

Mass of products equals mass of the reactants. If you build a campfire like this one, you start with a big pile of logs. As the fire burns, the pile of logs slowly shrinks. By the end of the evening, all that's left is a small pile of ashes.
