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?
Answer:
how many particles are pushing something
<span>The number of valence electrons from the electron configuration,write 1s², 2s² 2p⁶, 3s² 3p⁴.
The "big" numbers are the principal quantum numbers (n) which correspond to the major energy levels, and sub-scripted numbers are the number of electrons in the sub-energy level.
</span><span>For sulfur, the highest principal quantum number is 3, and there are 6 electrons in the 3s² and 3p⁴ sublevels. </span>
