Answer:
I don't remember how to label it, but it is 20.
Explanation:
The answer is 20 because once you dat the rock in the water, that is how much it changed.
Well that depends on the central atom. Remember each bond indicates another electron that is being shared with the central atom.
So CO4, carbon would be your central atom, with the 4 oxygen around it. There would be no double bonds because carbon only requires the 4 electrons provided by the oxygens, because of its location on the periodic table.
Nitrogen on the other hand is different. It's found in group 5 (5V) and has 5 valence electrons on its outer shell. So NO4 would have a central Nitrogen atom, with 3 oxygens providing a single bond, and one oxygen providing a double bond, because Nitrogen needs 5 electrons!
We learned it like this, the atom brought x amount of electrons to the party, x representing the valence electrons, and must leave with x electrons. It's silly but it works!
I hope I was able to help and clarify a few things up!
The neutralization reaction goes according to the scheme
H⁺ + OH⁻ = H₂O
acid and base react, salt and water are formed
NaOH + HNO₃ = NaNO₃ + H₂O
2KOH + H₂SO₄ = K₂SO₄ + 2H₂O
Answer:
Double Displacement reaction
Explanation:
BaCl2 + Na2SO4 → 2NaCl + BaSO4
Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.
