Допишіть формули продуктів реакції визначте коефіцієнти:Mg+HCI→...+H² CaCI²+AgNO→....+Ca(NO³)² FeCI³+KOH→KCI+..... NaOH+CO²→.....+H²O

Answer 1

Mg+2HCI→MgCl2+H²

CaCI²+2AgNO3→2AgCl+Ca(NO³)²

FeCI³+2KOH→2KCI+Fe(OH)2

2NaOH+CO²→Na2CO3+H²O

Answer 2

Reaction 1: Mg + HCl → H2 + MgCl2

The balanced equation for the reaction between magnesium (Mg) and hydrochloric acid (HCl) is:

Mg + 2HCl → H2 + MgCl2 [[1]]

In this reaction, magnesium reacts with hydrochloric acid to produce hydrogen gas and magnesium chloride.

Reaction 2: CaCl2 + 2AgNO3 → Ca(NO3)2 + 2AgCl

The balanced equation for the reaction between calcium chloride (CaCl2) and silver nitrate (AgNO3) is:

CaCl2 + 2AgNO3 → Ca(NO3)2 + 2AgCl [[2]]

In this reaction, calcium chloride reacts with silver nitrate to produce calcium nitrate and silver chloride.

Reaction 3: FeCl3 + 3KOH → 3KCl + Fe(OH)3

The balanced equation for the reaction between iron(III) chloride (FeCl3) and potassium hydroxide (KOH) is:

FeCl3 + 3KOH → 3KCl + Fe(OH)3 [[3]]

In this reaction, iron(III) chloride reacts with potassium hydroxide to produce potassium chloride and iron(III) hydroxide.

Reaction 4: NaOH + CO2 → NaHCO3

The balanced equation for the reaction between sodium hydroxide (NaOH) and carbon dioxide (CO2) is:

NaOH + CO2 → NaHCO3 [[4]]

In this reaction, sodium hydroxide reacts with carbon dioxide to produce sodium bicarbonate.

Reaction 5: H2O

The reaction between hydrogen gas (H2) and oxygen gas (O2) to produce water (H2O) is a well-known reaction. The balanced equation for this reaction is:

2H2 + O2 → 2H2O [[5]]

In this reaction, hydrogen gas reacts with oxygen gas to produce water.

Please note that the coefficients in the balanced equations represent the stoichiometric ratios of the reactants and products.
