When a mixture fizzes, it typically releases carbon dioxide gas. This can happen when a chemical reaction occurs that produces carbon dioxide as a byproduct, causing the fizzing reaction.
Hydrogen
carbon dioxide. CO32- + 2H+ -> CO2 + H2O
Carbon Dioxide
Oxygen is given off as a by-product os photosynthesis
A gas syringe is commonly used to measure the volume of gas given off or consumed in a reaction. This device allows for precise measurements and is often used in chemistry experiments to track gas production or consumption.
Carbon dioxide gas is given off when the indigestion powder containing sodium hydrogen carbonate and citric acid is added to water. This reaction produces effervescence and helps relieve indigestion symptoms by neutralizing excess stomach acid.
CO2. Under pressure you get carbonic acid (H2CO3) which spontaneously breaks up into CO2 and water.
None, no gas is given off.
Ammonia gas (NH3) is given off when ammonia solution is heated.
hydrogen eg:Na+HCl------>NaCl+H2
An observation is what you actually see happening. An inference is the conclusions you draw from that observation. To use an analogy; You may be doing a chemistry experiment and when you put two substances together, the mixture bubbles and brown gas comes off. You know that brown gas indicates nitrogen dioxide gas. The observation would be "Mixture bubbles and brown gas is given off" The inference would be "A gas is produced, nitrogen dioxide"

Hydrogen gas is given off when magnesium reacts with sulfuric acid.
Carbon Dioxide is given off. (CO2)
