Explanation:
Calcium is the element that has 2 valence electrons.
Answer:
the combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with.
Explanation:
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 .
1 hectoliter is 26.4172
1 kiloliter is 264.172
