Question

ПОМОГИТЕ ПОЖАЙЛУСТА!! В приведенных схемах расставьте коэффициенты и укажите тип реакции: MnO2 + C = CO + Mn KOH + HNO3 = KNO3 + H2O Al(OH)3 = Al2O3 + H2O HgO = Hg + O2 Zn + H2SO4 = ZnSO4 + H2 P + O2 = P2O5

Answer 1

MnO₂ + 2C = 2CO + Mn (реакция разложения)

KOH + HNO₃ = KNO₃ + H₂O (реакция обмена)

2Al(OH)₃ = Al₂O₃ + 3H₂O (реакция разложения)

2HgO =2Hg + O₂ (реакция разложения)

Zn + H₂SO₄ = ZnSO₄ + H₂ (реакция замещения)

4P + 5O₂ = 2P₂O₅ (реакция соединения)

Answer 2

Balancing Chemical Equations

To balance the chemical equations provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go through each equation and balance them one by one.

1. MnO2 + C = CO2 + Mn - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: MnO2 + 4C = 2CO2 + Mn [[1]].

2. KOH + HNO3 = KNO3 + H2O - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2KOH + HNO3 = KNO3 + H2O [[2]].

3. Al(OH)3 = Al2O3 + H2O - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2Al(OH)3 = Al2O3 + 3H2O [[3]].

4. HgO = Hg + O2 - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: 2HgO = 2Hg + O2 [[4]].

5. Zn + H2SO4 = ZnSO4 + H2 - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: Zn + H2SO4 = ZnSO4 + H2 [[5]].

6. P4 + O2 = P2O5 - To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. - The balanced equation is: P4 + 5O2 = 2P2O5 [[6]].
