The reaction formula is 2HCl + Mg = MgCl2 + H2. There are one atom of magnesium involved and the number of atoms will not change, So the answer is one magnesium ion.
Atoms are the smallest bits of ordinary matter and are made from particles called protons, neutrons and electrons while a An element is a substance that is made entirely from one type of atom
Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%
francium , in the Periodic table the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. making helium is the smallest element, and francium the largest.
If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered or extinct.
