Question

Закончить уравнения реакций:Cu + HCl (конц.) →Zn + HNO3 (разб.) →

Answer 1

1)Cu+HCl===> CuCl2 + H2(протекает при 600-700 гр Цельсия, реакция идет с HCl в газовом состоянии, а не с жидким HCl)

2)3Zn+8HNO3====>  3Zn(NO3)2 + 4H2O + 2NO

Answer 2

Balancing Chemical Equations:

To balance the chemical equations provided, we'll start with the given unbalanced equations and balance them step by step.

1. Cu + HCl (conc.) → The unbalanced equation is: Cu + HCl → To balance this equation, we need to ensure that the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side.

The balanced equation is: Cu + 2HCl → CuCl2 + H2.

2. Zn + HNO3 (razb.) → The unbalanced equation is: Zn + HNO3 → To balance this equation, we'll follow the same process of ensuring the number of atoms of each element on both sides of the equation is equal.

The balanced equation is: Zn + 2HNO3 → Zn(NO3)2 + H2.

Final Balanced Equations:

1. Cu + 2HCl → CuCl2 + H2 2. Zn + 2HNO3 → Zn(NO3)2 + H2

These are the balanced chemical equations for the given reactions.
