Question

Na=>Na2O=>NaOH Решить:​

Answer 1

Ответ:

Na => Na2O => NaOH

1) 4Na + O2 => 2Na2O(соед.) (оксид натрия)

2) Na2O + H2O => 2NaOH(соед.) (гидроксид натрия)

Answer 2

Balancing Chemical Equation

To balance the chemical equation Na + H2O -> Na2O + H2, we need to ensure that there are an equal number of each type of atom on both sides of the equation.

First, let's break down the equation into its individual components: - Reactants: Na, H2O - Products: Na2O, H2

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

1. Balance the sodium (Na) atoms: - There are 2 Na atoms on the product side (Na2O), so we need to put a coefficient of 2 in front of Na on the reactant side. - The equation now looks like this: 2Na + H2O -> Na2O + H2

2. Balance the hydrogen (H) atoms: - There are 2 H atoms in the water (H2O) on the reactant side, and 2 H atoms in the hydrogen gas (H2) on the product side, so the hydrogen atoms are already balanced.

3. Balance the oxygen (O) atoms: - There are 1 O atom in the water (H2O) on the reactant side, and 1 O atom in the sodium oxide (Na2O) on the product side, so the oxygen atoms are already balanced.

Now the equation is balanced: 2Na + H2O -> Na2O + H2

This balanced equation ensures that the same number of each type of atom is present on both sides of the chemical equation.
