Question

Составить уравнение хим. Реакций ?+?=Na2Zn02+H2O ?+?=NaCl+H2O+CO2

Answer 1

2NaOH + Zn(OH)2 -> Na2ZnO2 + 2H2O
Na2CO3 + 2HCl -> 2NaCl + CO2 + H2O

Answer 2

Chemical Equation Balancing

To balance the chemical equation provided, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's how we can balance it:

Na2ZnO2 + H2O = NaCl + H2O + CO2

First, let's identify the elements present in the equation: - Sodium (Na) - Zinc (Zn) - Oxygen (O) - Hydrogen (H) - Chlorine (Cl) - Carbon (C)

Now, let's balance the equation step by step:

1. Balance the metals: - The left side has 2 sodium atoms (Na2), while the right side has 1 sodium atom (NaCl). To balance this, we can put a coefficient of 2 in front of NaCl: Na2ZnO2 + H2O = 2NaCl + H2O + CO2

2. Balance the non-metals: - The left side has 2 oxygen atoms (O2), while the right side has 1 oxygen atom (CO2). To balance this, we can put a coefficient of 2 in front of CO2: Na2ZnO2 + H2O = 2NaCl + H2O + 2CO2

3. Balance the hydrogen atoms: - The left side has 2 hydrogen atoms (H2O), while the right side has 1 hydrogen atom (H2O). The hydrogen atoms are already balanced.

Now, the balanced chemical equation is: Na2ZnO2 + H2O = 2NaCl + H2O + 2CO2 [[1]](https://www.chemicalaid.com/tools/equationbalancer.php?hl=en)

Please note that the water (H2O) appears on both sides of the equation and can be canceled out.
