Water containing carbonic acid and calcium
Yes, because it comes from a one thing and spreads throughout the entire space. Similar to dripping foot coloring into a glass of water, or spraying air freshener.
(3.5mol)(24.106 g/1mol c6h6) =84.371 g C6H6
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 .
