If X is an equivalent base to H₂O
HX is an equivalent acid to H₃O⁺
HX is a stronger acid than H₃O⁺
HX is not an acid
X⁻ is a stronger base than H₂O
HX is a weaker acid than H₃O⁺
X⁻ is a weaker base than H₂O
X⁻ is not a base.
The correct response or this is
X⁻ is a stronger base than H₂O
HX is a weaker acid than H₃O⁺
Answer:
D- 31.9988 g/mol
Explanation:
The molar mass of a substance is the mass in grams of one mole of the substance. For a compound, the molar mass is the gram - formula mass or gram - molecular weight. It is determined by the addition of its component atomic masses;
To find molar mass of O₂;
Atomic mass of O = 15.9994g/mol
Molar mass of O₂ = 2(15.9994) = 31.9988g/mol
Answer:
pure substance
Explanation:
A pure substance is a form of matter that has a constant composition (meaning it's the same everywhere) and properties that are constant throughout the sample (meaning there is only one set of properties such as melting point, color, boiling point, etc. throughout the matter).Ja
Answer:
2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃
Explanation:
When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):
NaOH + H₂SO₃ → H₂O + Na₂SO₃
To balance the sodiums:
2NaOH + H₂SO₃ → H₂O + Na₂SO₃
And the hydrogens:
<h3>2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃</h3><h3 />
And this is the complete reaction for this neutralization reaction.
The answer is ignore this thanks
