can you plse show me a link that links to a picture that explains the law of coservation of matter
Since this is not my area of expertise, I searched Google under the key words "'conservation of matter' picture" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
