Is 2H2O>2H2+O2 a balanced equation

Yes

Explanation:

To prove that the equation is balanced, the total sum of individual atomic mass on both left hand side and right hand side should be equal. For this case

Left hand side

2H2O means 2*2=4H

2O=2O

Right hand side

2H2+02

2*2 =4H

2O=2O

Clearly, this shows that both the right hand side and left hand side have equal hydrogen and oxygen atoms, with each side having 4 hydrogen atoms a s 2 oxygen atoms.

Therefore, the equation is balanced

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
