It would be C! An energy change. Usually it changes heat - could be less or more.
I hope all is well, and you pass! Good luck, rockstar! You got this. (:
:1because they release large amount of haet per effective mass when burned
Addition Einstein eqn Energy=mass×freq
2 Small byproduct is smokes and ashes
Answer:
# In a familiar high-school chemistry demonstration, an instructor first uses electricity to split water into its constituent gases, Hydrogen and Oxygen. Then, by combining the two gases and igniting them with a spark, the instructor changes the gases back into water with a loud pop (That means the energy is released in the process).
# There are new other ways to produce water in laboratory, however, the scientists can not produce water in large quantity for the masses, because of some reasons.
1- Theoretically, this is possible, but it would be an extremely dangerous process. Since Hydrogen is extremely flammable and Oxygen supports combustion, it wouldn’t take much to create this force, but we also have an explosion. That’s why this process can be a deadly one if our experiment is big enough.
2- Personally, I think that it makes no sense to produce water in a laboratory ( or in a large plant) for people to use as daily water. The much more important thing we need to do is to save our environment, our planet Earth. Because the daily water people drink contains not just water molecules but other minerals, the marine life is depend not just in water molecules but diferent factors, etc.
Explanation:
This is just my personal opinion. Hope that can help you a little. Have a nice day
Answer: B
Explanation: I had an even lengthier explanation but Brainly is being a butthead. But I got it right on my test for those who want to know.
The only chemical that is a liquid at room temperature is Mercury. It's toxic, and has a high vapor pressure at room temperature.
