19. The atomic number is the same as protons and electrons unless it have a - or a + charge the electrons are going to change
<h2>The required "options are (II), (III), and (IV)".</h2>
Explanation:
Postulates of Dalton's atomic theory which are scientifically accepted are:
- Atoms are indestructible.
- Compounds are combinations of different atoms.
- A chemical reaction changes the way atoms are grouped together.
Postulates of Dalton's atomic theory which are not accepted scientifically are:
- All atoms of the same elements are identical.
The theory states that the atoms of the same element are identical in every aspect but it is now scientifically proved that the same element should differ in their mass which is known as isotopes.
4Ag + 2H2S + O2 -> 2Ag2S + 2H20 i’m pretty sure that’s correct
I’m pretty sure it’s none of the above cause I’m googling it a bunch and and it say you use the dideoxy method
