i think it is just double displacement.
Germanium forms various compounds, including germanium dioxide (GeO2), germanium tetrachloride (GeCl4), and germanium tetrafluoride (GeF4). These compounds are commonly used in the production of semiconductor materials and optical fibers.
When phosphoric acid reacts with ammonium bifluoride, it forms ammonium phosphate and hydrofluoric acid. Ammonium phosphate is commonly used as a fertilizer, while hydrofluoric acid is a toxic and corrosive substance.
When nitrogen dioxide reacts with water, it forms nitric acid and nitrogen monoxide.
When sodium fluoride reacts with diluted nitric acid, it forms hydrofluoric acid (HF) and sodium nitrate (NaNO3). This reaction is represented by the equation: NaF + HNO3 -> HF + NaNO3. Hydrofluoric acid is a weak acid that can be corrosive and toxic.
Carbon dioxide gas is produced when limestone, which contains calcium carbonate, reacts with an acid. This reaction forms calcium acetate, water, and carbon dioxide gas.

When fluorine reacts with water, it forms hydrofluoric acid (HF) and releases oxygen gas. Hydrofluoric acid is a weak acid that can cause skin burns and is toxic if ingested or inhaled. The reaction is highly exothermic and should be conducted with caution.

Carbonic acid forms when water reacts with carbon dioxide.
Sulfur dioxide produces Sulfurous acid when dissolved in water.SO2 + H2O ----> H2SO3Nitrogen dioxide produces Nitrous acid and Nitric acid when dissolved in water.2 NO2 + H2O ----> HNO2 + HNO3
Carbon dioxide gas is produced when limestone, which contains calcium carbonate, reacts with an acid. This reaction forms calcium acetate, water, and carbon dioxide gas.
When oxygen reacts with carbon monoxide, it forms carbon dioxide. This reaction releases energy and is often used in combustion processes. Carbon monoxide is oxidized to carbon dioxide in the presence of excess oxygen.
When rainwater reacts with carbon dioxide in the soil, it forms carbonic acid. This weak acid can further contribute to the weathering of rocks and minerals in the soil.
When carbon is exposed to air nothing happens.
When limewater (calcium hydroxide solution) reacts with carbon dioxide, it forms a white precipitate of calcium carbonate. This is a chemical reaction that is often used to test for the presence of carbon dioxide gas.
