Answer:
there are 4 hydrogen so
A.the mass of Hydrogen in the reactant side of the equation above is 1×4=4 amu.
B.the mass of Hydrogen on the product side of the equation above =1×4=4 amu.
<u>Note</u><u>:</u><u> </u><u>mass</u><u> </u><u>of</u><u> </u><u>reactant</u><u> </u><u>=</u><u>mass</u><u> </u><u>of</u><u> </u><u>product</u><u>.</u>
Calcium & Barium. Elements that share same/similar properties lay on the same group/family on the periodic table!
Answer:
, CaCO3, contains one atom of calcium, one of carbon and three of oxygen. so t<u>here are 5 atoms in CaCO3</u>
Mg(OH)2, There is one magnesium, two oxygen, and two hydrogen atoms. so <u>there are 5 atoms Mg(OH)2</u>
a molecule of acetic acid contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. <u>so there are 8 atoms in acetic acid </u>
There are <u>3 atoms in CaCl2</u>
H2SO4 is a chemical compound made up of two hydrogen atom, one sulfer atom, and four oxygen atoms. <u>So there are 7 atoms in H2SO4</u>
There are <u>8 atoms in sodium phosphate</u>
