PLEASE HELP!!!
Hydrogen and oxygen react to form water. At an atomic level, how do we know that a chemical reaction has occurred? *
1 point
Hydrogen molecules are negative, and oxygen positive.
For every oxygen atom, two hydrogen atoms are needed.
The hydrogen and oxygen atoms regroup into a new molecule.
Oxygen atoms are much larger than hydrogen atoms.

Answer 1

Answer:

Explanation:

The hydrogen and oxygen atoms regroup into a new molecule.

Look into intermolecular forces! :) it will show you different types of bonding/how molecules will bond

Answer 2

We know that a chemical reaction has taken place because hydrogen and oxygen atoms regroup into a new molecule.

A chemical reaction is said to have occurred when there is a rearrangement of atoms in two or more substances. This rearrangement of atoms often leads to the formation of a new substance.

At an atomic level, when hydrogen and oxygen react, we know that a chemical reaction has taken place because hydrogen and oxygen atoms regroup into a new molecule.
