I'm pretty sure its metals.
Answer:
2.1 M
Explanation:
Molarity is moles per liter:
0.512 mol NaCl / 0.24 L = 2.1 M
Ethene (C2H4)
Propene (C3H6)
Butene (C4H8)
Pentene (C5H10)
Hexene (C6H12)
Answer:
Explanation:
HF ,Hydrofluoric acid happens to be a weak acid and as we know that a weak acid is partially dissociated in water.
So when we dissolve HF in water it would subsequently dissociate into H⁺ and F⁻ions . The solution now would contain hydronium ion that is H+ ion.
The solution would also contain dissociated F⁻ ion and solvent H20 molecules.
The following reaction would take place:
HF+H₂O⇆H₃O⁺+F⁻
so the reaction in forward direction is the dissociation of HF into H₃O⁺(that is H⁺) and F⁻ion.
The backward reaction would be the recombination of H₃O⁺(that is H⁺) and F⁻ion to give back HF and H₂O
