d, one atom of oxygen and two atoms of hydrogen
What do you need help with. I am very good at chemistry.
The subscript in a chemical formula is the number written next to the element at the bottom part. For example, the chemical formula of water is H₂O. The subscript of H is 2, while the subscript of O is 1. The subscript represents the number of a certain element in one particle of the compound. So, if you change the subscript, you also change the number of a certain element per compound. In other words, you change the ratio.
60 elements! I don't exactly know every element known, so if you are asking that, please tell us, but what I do know is that there were 60 elements in the periodic table by 1860.
Well just wait for the right time to come, Because if you wait for the right time, you're gonna find someone who you really want- I'm bad at understanding tagalog
