Question

6. NaOH + H 3 PO 4 → Na 3 PO 4 + H 2 O 7. КС1О 3 → КС1 + О 2 8. Сr + С1 2 → СrС1 3 9. NaNО 3 → NaNО 2 + О 2

Answer 1

Ответ:

6.) 3NaOH + H³PO⁴ = Na³PO⁴ + 3H²O

7.) 2KClO³ = 2KCl + 3O²

8.) 2Cr + 3Cl² = 2CrCl³

9.) 2NaNO³ = 2NaNO² + O²

Answer 2

It seems like you've written a set of chemical equations. These equations represent chemical reactions. Here's how you can interpret each of them:

6. NaOH + H3PO4 → Na3PO4 + H2O This is a neutralization reaction between sodium hydroxide (NaOH) and phosphoric acid (H3PO4). It forms sodium phosphate (Na3PO4) and water (H2O) as products.

7. KClO3 → KCl + O2 This is a decomposition reaction. Potassium chlorate (KClO3) decomposes into potassium chloride (KCl) and oxygen (O2) gas.

8. Cr + Cl2 → CrCl3 This is a synthesis reaction. Chromium (Cr) reacts with chlorine gas (Cl2) to form chromium chloride (CrCl3).

9. NaN3 → NaNO2 + O2 This is a decomposition reaction. Sodium azide (NaN3) decomposes to produce sodium nitrite (NaNO2) and oxygen (O2) gas.

These reactions are balanced chemical equations that show the reactants on the left side and the products on the right side. The coefficients in front of each compound ensure that the equation obeys the law of conservation of mass, meaning that the number of atoms of each element is the same on both sides of the equation.
