Put a balloon over the top of the test tube. If the balloon inflates, it is from the gas that was produced.
The gas produced in the reaction between hydrogen and potassium is hydrogen gas (H2). This reaction is highly exothermic and violent, producing a bright light and a pop sound due to the rapid formation of hydrogen gas.
Sodium vigorously reacts with water, producing hydrogen gas and sodium hydroxide. The reaction is highly exothermic and can even ignite the hydrogen gas produced.
When bread rises, it is a sign that yeast, a type of fungus, is producing carbon dioxide gas through fermentation. The carbon dioxide gas gets trapped within the dough, causing it to rise and create a light, airy texture in the bread.
Yes, the reaction of methane gas with oxygen gas to produce carbon dioxide and water is a combustion reaction. Combustion reactions are characterized by the rapid reaction of a substance with oxygen, often producing heat and light as byproducts.
Sodium can react very rapidly with water, producing hydrogen gas and heat as a result of the exothermic reaction. The reaction is vigorous and can sometimes lead to explosions due to the rapid release of heat and gas.

2AgNo3OH(I) + 3O2(g) -> 2CO2(g) + 4H2O(l) (from Apex)
Sodium can react very rapidly with water, producing hydrogen gas and heat as a result of the exothermic reaction. The reaction is vigorous and can sometimes lead to explosions due to the rapid release of heat and gas.
The reaction between magnesium and oxygen gas to produce magnesium oxide is a combustion reaction. Combustion reactions are exothermic, producing light and heat as they release energy in the form of heat.
Producing salt and producing hydrogen gas are not redundant in this reaction. When sodium metal reacts with hydrochloric acid, salt (sodium chloride) is formed along with the release of hydrogen gas.
When you mix hydrochloric acid (HCl) with magnesium (Mg), a chemical reaction will occur, producing hydrogen gas and magnesium chloride. The reaction can be written as: 2HCl + Mg -> MgCl2 + H2. This reaction will also release heat.
An "exothermic" reaction.
