To fill in the blank, the correct word is Mixture.
What is a Mixture?
- Matter that can vary in its composition is a(n) mixture.
- The substances that make up mixtures are not bonded together.
If they are in the same group they have the same valence electrons but since I cannot see what you’re talking about I’m not sure what your question is
Answer:
MgBr2
Explanation:
(Mg^2+) + (Br^1-)
For every Mg we need 2 Br to balance out the compound.
Answer:
Some metals can be extracted from compounds by heating with carbon atom because they are less reactive than carbon and some metals cannot be extracted because they are more reactive than carbon atom.
Explanation: If the metal is less reactive than carbon atom so the carbon atoms make bond with oxide or other atom present with metal and the metal is free from that oxide or that element. But if the reactivity of metal is higher than carbon is unable to remove the oxide or element.
