Okay, so what you first do with this type of question is think about what a chemical change is. A chemical change is a change that can not be reversed. A physical change is something that can be reversed or done using temperature. e.x. Water freezing into ice is a physical change, where as combining vinegar and baking soda together releases a gas, which is chemical, or iron rusting in the presence of oxygen. Which one of these equations has one chemical molecule set that produces a different set?
Sorry man, this isn’t really my cup of tea
Hello there!
The nuclear emanations 1, 2 and 3 are called, respectively:
1) Alpha, beta and gamma
Alpha Radiation consists of two protons and two neutrons, as protons are positive particles, they will be attracted to the negatively charged plate.
Beta Radiation is composed of a high-energy electron. As electrons are negative particles, they will be attracted to the positively charged plate.
Gamma Radiation is composed or photons. Photons don't have charge or mass, and they will not be attracted to the charged plates. This kind of radiation is more penetrating than the other two.
Have a nice day!
They are both physical changes (change in physical structure/appearance)
hope this helps :)
