PLEASE HELP!!!!!!!!Which of the following chemical reactions is best clasified as an acid-base reaction?
ANTONII [103]

Answer:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

Explanation:

  • The given reactions are:

a . 2HgO → 2Hg + O₂,

It is a decomposition reaction, that HgO is decomposed to give Hg and O.

b . Na₂SO₄ + BaCl₂ → BaSO₄ + 2NaCl,

It is a double replacement reaction where two salts replaces their cations and anions with each others producing 2 new salts.

c . Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag,

It is a single replacement reaction, that Zn replaces Ag from its salt.

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

It is acid-base reaction "neutralization reaction" where H₂SO₄ (acid) reacts with KOH (base) producing K₂SO₄ (salt) and water.

  • So, the right choice is:

<em>d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O</em>

If the balanced chemical reaction for the formation of Li2O is 4 Li(s) + O2(g) → 2 Li2O(s), how many molecules of Li2O(s) would
Marta_Voda [28]

The molecules of Li₂O that would produce if you used up 6 atoms of Li(s) is 3.

<h3>What is Lithiumdioxide?</h3>

It is an unstable inorganic and radical compound, used in the manufacture of glass and ceramic.

The balanced equation

\rm 6 Li(s) + O_2(g) \rightarrow 3 Li_2O(s)

If the atoms of lithium moves up to 6 the lithium oxide molecules will be 3, as you can see in the equation.

Thus, the molecules of Li will be 3.
