Hey are you ready for the test we are taking next period?
Its 10:45 ,Mike and Emily are about to go to lunch,but Emily isn't positive about today's test.
NO! I don't really know what the conservation of mass is or what it has to do with chemical equations.
But,would you like to explain it on the way to Lunch?
Ok,so The Conservation of Mass states that matter can not be created nor destroyed.
On the way to Lunch Mike explained what the conservation of mass states.
Ok,But what does that have to do with Chemical Equations?
Well since the conservation of mass states that mass can't be created nor destroyed.This means that a chemical equation must show the same number of atoms on both sides of the arrow.
In the lunch room Mike is explaining what chemical equations have to do with the conservaton of mass.
Can you give a example?
Water is made up of 2 Hydrogen atoms and 1 Oxygen Atoms.
The chemical equation for water is 2H2 + O2 =2H2O
In this example i am going to talk about this glass of Water.
And well since this equation shows the same number of atoms water can not be destroyed nor created.
Ok so the conservation of mass states that mass can't be created nor destroyed,Which also states that a chemical equation has to have the same amount of atoms in both sides of the arrows.for examples waters chemical equation 2H2+ O2 =2H20
During Lunch Emily started to understand the lesson more and more and was positive about the test.
Ok! I think i got it.
The atoms include both protons and neutrons in its nucleus and electrons in it outer most shell. but i already knew that.
