Question

Закончить уравнения реакций Be+HCL+H2O→... Be(OH)2+NaOH→... BeF2+SiF4→... MgCl2+Na2CO3+H2O→... Ca3(PO4)2→...

Answer 1

Ответ:

Объяснение:

Be + 2HCl + 4H₂O = (Be(H₂O)₄)Cl₂ + H₂

Be(OH)₂ + 2NaOH = Na₂(Be(OH)₄)

BeF₂ + SiF₄ = Be(SiF₆)

MgCl₂ + Na₂CO₃ + H₂O = Mg₂(OH)₂CO₃ + 2NaCl + CO₂

Ca₃(PO₄)₂ = 3CaO + P₂O₅

Answer 2

Balancing Chemical Equations

Let's balance the given chemical equations step by step.

Balancing the Equation: Be + HCl + H2O → Be(OH)2 + NaOH

The unbalanced equation is: Be + 2HCl + 2H2O → Be(OH)2 + 2NaOH

Balanced equation: Be + 2HCl + 2H2O → Be(OH)2 + 2NaOH

Balancing the Equation: Be(OH)2 + NaOH →

The unbalanced equation is: Be(OH)2 + 2NaOH →

Balanced equation: Be(OH)2 + 2NaOH → Na2Be(OH)2

Balancing the Equation: BeF2 + SiF4 →

The unbalanced equation is: BeF2 + SiF4 →

Balanced equation: BeF2 + SiF4 → BeSiF6

Balancing the Equation: MgCl2 + Na2CO3 + H2O →

The unbalanced equation is: MgCl2 + Na2CO3 + H2O →

Balanced equation: MgCl2 + Na2CO3 + H2O → Mg(OH)2 + 2NaCl + CO2

Balancing the Equation: Ca3(PO4)2 →

The unbalanced equation is: Ca3(PO4)2 →

Balanced equation: Ca3(PO4)2 → 3Ca + 2P + 8O2
