Answer 1

........................

Answer 2

2HCI+HgO=HgCI2+H2O
2HCI+Mg=MGCI2+H2
6HCI+Fe2O3=2FeCI3+3H2O
2HCI+Mg(OH)2=MgCI2+2H2O

Answer 3

HCl + HgO = ?

The reaction between hydrochloric acid (HCl) and mercury(II) oxide (HgO) can be represented by the following equation:

2HCl + HgO -> HgCl2 + H2O

In this reaction, hydrochloric acid reacts with mercury(II) oxide to produce mercury(II) chloride and water. The balanced equation shows that 2 moles of hydrochloric acid react with 1 mole of mercury(II) oxide to produce 1 mole of mercury(II) chloride and 1 mole of water.

HCl + Hg = ?

The reaction between hydrochloric acid (HCl) and mercury (Hg) can be represented by the following equation:

HCl + Hg -> HgCl2

In this reaction, hydrochloric acid reacts with mercury to produce mercury(II) chloride. The balanced equation shows that 1 mole of hydrochloric acid reacts with 1 mole of mercury to produce 1 mole of mercury(II) chloride.

HCl + Mg = ?

The reaction between hydrochloric acid (HCl) and magnesium (Mg) can be represented by the following equation:

2HCl + Mg -> MgCl2 + H2

In this reaction, hydrochloric acid reacts with magnesium to produce magnesium chloride and hydrogen gas. The balanced equation shows that 2 moles of hydrochloric acid react with 1 mole of magnesium to produce 1 mole of magnesium chloride and 1 mole of hydrogen gas.

HCl + SO2 = ?

The reaction between hydrochloric acid (HCl) and sulfur dioxide (SO2) can be represented by the following equation:

HCl + SO2 -> H2O + SO2Cl2

In this reaction, hydrochloric acid reacts with sulfur dioxide to produce water and sulfuryl chloride. The balanced equation shows that 1 mole of hydrochloric acid reacts with 1 mole of sulfur dioxide to produce 1 mole of water and 1 mole of sulfuryl chloride.

HCl + Fe2O3 = ?

The reaction between hydrochloric acid (HCl) and iron(III) oxide (Fe2O3) can be represented by the following equation:

6HCl + Fe2O3 -> 2FeCl3 + 3H2O

In this reaction, hydrochloric acid reacts with iron(III) oxide to produce ferric chloride and water. The balanced equation shows that 6 moles of hydrochloric acid react with 1 mole of iron(III) oxide to produce 2 moles of ferric chloride and 3 moles of water.

HCl + KOH = ?

The reaction between hydrochloric acid (HCl) and potassium hydroxide (KOH) can be represented by the following equation:

HCl + KOH -> KCl + H2O

In this reaction, hydrochloric acid reacts with potassium hydroxide to produce potassium chloride and water. The balanced equation shows that 1 mole of hydrochloric acid reacts with 1 mole of potassium hydroxide to produce 1 mole of potassium chloride and 1 mole of water.

HCl + Mg(OH)2 = ?

The reaction between hydrochloric acid (HCl) and magnesium hydroxide (Mg(OH)2) can be represented by the following equation:

2HCl + Mg(OH)2 -> MgCl2 + 2H2O

In this reaction, hydrochloric acid reacts with magnesium hydroxide to produce magnesium chloride and water. The balanced equation shows that 2 moles of hydrochloric acid react with 1 mole of magnesium hydroxide to produce 1 mole of magnesium chloride and 2 moles of water.

I hope this helps! Let me know if you have any other questions.
