Answer:
the answer is C. 3. measure the mass of the liquid in both beakers
The percent composition by mass for sodium (Na) in Sodium phosphate (Na₃PO₄) : 42.07%
<h3>Further explanation</h3>
Given
Compound of Sodium phosphate (Na₃PO₄)
Required
The percent composition by mass for sodium (Na)
Solution
<em>The Comparative Law (Proust ) : compounds are formed from elements with the same Mass Comparison</em>
MW Na₃PO₄ = 163,94 g/mol
Ar Na=22,989769g/mol
Answer:
a.) CO3 ^ 2-.
b.) C6H5NH2.
c.) C2H5NH2.
Explanation:
water is an ionizable compound, which when being ionized forms a structure, called OH- hydroxyl, when it is ionized it acquires the ionic binding capacity with other chemical compounds.
Amoeba are those Organisms which reproduce through binary fission.
Answer:
The 3rd answer down.
Na²O (sodium oxide) will be a base when exposed to water H²O
Explanation:
Sodium Oxide Na²O, will become Sodium Hydroxide after being exposed to water (at 80% I believe).
The oxygen ion in Na²O has 2 extra electrons which makes it highly charged and very attractive to hydrogen ions. The attraction is so strong that when Na²O comes in contact with H²O, the O(-2) strips off a hydrogen from water, forming 2 x OH ions which of course are still strongly basic.
