Carbon dioxide (CO2) and water (H2O) are obtained by burning organic compounds. By increasing the consumption of fossil fuels, we release much more CO2 into the atmosphere than nature can handle. It disrupts various equilibrium processes on our planet, and in addition, CO2 acts like a layer of nylon in a greenhouse - that is, it retains heat and supports the rise in temperature. In the reaction of vinegar and baking soda, carbon dioxide is released, which is heavier than air in higher concentrations. When the contents of the glass are "poured" onto the candles, the flow of oxygen is prevented and the candles go out. This is the principle of operation of some fire extinguishers.
