While there are many more (somewhat more obscure) conservation laws throughout physics (like "Conservation of Lepton Number"), I believe the four you may be referring to are Conservation of Matter Conservation of Energy Conservation of Charge Conservation of Momentum NOTE that Conservation of Matter is not a true law (it is broken in many nuclear reactions). The other three are laws.
It makes us feel more pride in ourselves as Americans.

Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
yes,it is important.Our ancestors tell us more about kings and queens who lived long ago.
