I WILL GIVE FREE PIONTS AND BRAINLIEST IF YOU ARE CORRECT! PLEASE ANSWER ITS DUE TODAY!!!

Explanation:

This image is a good example of the law of conservation of mass because it shows that mass is not created or destroyed. We can see this in the picture because there's 4 hydrgen and 2 oxygen atoms in the reactants (the left side of the arrow) and there's 2 oxygen atoms and 4 hydrogen atoms in the products (right side of the arrow). Since there's the same amount of atoms on both sides, then law of conservation of mass applies.

Stealing your points like how you stole mine! +*♡

Don't answer someone's question with some nonsense and then delete it; especially when I spent over an hour on that one question. I will surely delete my answers after this and still have my 15 points...

don't reap what you sow :)

You can search that up if you don't even know what that means.

Have a nice day! +*♡

Hope this helped.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
