Question

Thanks,

Answer 3

Sorry I know this was 5 months ago but basically you don't understand what to do just read through the assessment. You are just writing an essay about chemical change, for example, the questions for the tobacco leaf, "what happens to the molecules in each object as they change?". You can search up research about the tabbacqo leaf to help you or learn more from the other assignments explaining what chemical and physical change is.

( sorry if I didn't really help :// )

yo can u just give us the answers

Answer 5

bot why does a small explosion happen when you pour a fuel liquid into a test cube ?

Answer 6

A small explosion can happen when you pour a fuel liquid into a test tube because of the rapid chemical reaction that occurs between the fuel and the oxygen in the air. This reaction releases a large amount of energy in the form of heat and light, leading to the explosion. The fuel vaporizes in the presence of heat, mixes with oxygen from the air, and undergoes combustion, resulting in the explosion. It's important to note that this kind of experiment should be done with proper safety precautions and under the guidance of a teacher or experienced professional.
