Why does the chemical reaction seen here obey the law of conservation of matter?
<u><em>Answer:</em></u>
Because there are the same number of atoms of each element shown on both sides
<u><em>Explanation</em></u>
As in chemical reactions, atoms bonds are break and new bonds are formed. As new substance are formed but overall they have same elements, no new elements come from outside or go to outside. In other words , rearrangement of atoms take place but number of atoms remained same.
NaOH + HCl -----> NaCl + H2O
As in above reaction there are the same number of atoms of each element shown on both sides .
when naming ionic compounds — those are only used in naming covalent molecular compounds. Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound. since iron can form more than one charge.
