Answer:
A
Explanation:
this is because density is the mass per unit volume of an object
Al(NO3)3(aq) + 3NaOH(s) --> Al(OH)3 (s) + 3NaNO3 (aq)
The precipitate here is Al(OH)3 (s), since the solid reactant is the precipitate in the aqueous solution. Usually, it is okay to assume in basic chemistry that the transition metal is going to be part of the compound that is the precipitate, especially in an acidic salt and a strong base reaction that we have here.
Reactants bonds are broken and products bonds are formed
Answer:
oxidation
Explanation:
oxidation number are based on the distribution of electrons in a molecule
