Yes that’s correct it is B
Answer:
All of them
Explanation:
All of those are properties of metals
When an iron is dipped in Copper Sulphate
Solution this reaction between them and
copper sulphate change into blue color to light
green color. This show that iron is more
reactive then copper, it can to replace copper
from CuSO4 , CuSO4 is of blue color and
FeSO4 is light green color.
Hope it helps
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 .
