Answer:
Na-O
Be-S
Explanation:
ionic bonds= metal and non metal
Answer:
Cu(s) + 2AgNO3(aq)→Cu(NO3)2(aq)+2Ag(s)
This chemical equation means:
One mole of solid copper plus two moles of aqueous silver nitrate produce one mole of copper(II) nitrate plus two moles of solid silver.
This is a single replacement reaction in which the metal copper replaces the metal silver.
Answer:
mass and distance
Explanation:
The strength of this force depends on the <u>mass</u>
of each object and
the <u>distance</u>
between them.
4. 4 C + S8 = 4 CS2
5. H2 + O2 = H2O2 is already balanced.
6. 4 Na + O2 = 2 Na2O
I think mercury for element and sodium hypochlorite
