Water is formed when hydrogen gas burns (reacts) with oxygen (from air)
2 H2(g) + O2(g) --> 2H2O(l)
When fire burns logs, a chemical change is taking place. The heat from the fire causes the wood to undergo combustion, which is a chemical reaction that breaks down the wood's molecular structure and releases energy in the form of heat and light.
The type of reaction taking place in Q2 is hydrolysis. Hydrolysis is a chemical reaction where water is used to break down a compound into its constituents.
The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.
The chemical reaction between aluminum and hydrochloric acid can be represented by the balanced equation: 2Al + 6HCl → 2AlCl₃ + 3H₂. In this reaction, aluminum (Al) reacts with hydrochloric acid (HCl) to produce aluminum chloride (AlCl₃) and hydrogen gas (H₂). The evolution of hydrogen gas, which can be observed as bubbles, indicates that a chemical reaction is taking place. This process is an example of a single displacement reaction.
Light reaction is taking place on thylakoids.Dark reaction take place in stroma.
The nuclear reaction taking place inside the sun is called nuclear fusion. This is where hydrogen atoms combine to form helium, releasing a large amount of energy in the process.
The combustion of butane to produce a flame is a chemical reaction known as a combustion reaction. In this reaction, butane reacts with oxygen to produce carbon dioxide, water, and heat energy.
Reaction that takes place when magnesium burns in air= Magnesium + Oxygen = Magnesium Oxide (magnesia)

We can see bubbles of gas being released. The gas is a new substance, so this is evidence that a chemical reaction is taking place. the gas released during this reaction is hydrogen.

The reaction is likely an endothermic reaction. In an endothermic reaction, heat is absorbed from the surroundings, causing a decrease in temperature.
Metals like calcium react with water to form metal hydroxide and hydrogen gas. The hydrogen gas bubbles produced during the reaction create buoyant forces that cause the metal to float on the surface of the water.
When celery is added to hydrogen peroxide, a reaction occurs due to the presence of the enzyme catalase in the celery. Catalase breaks down hydrogen peroxide into water and oxygen gas, resulting in the release of bubbles. This reaction is an example of an enzymatic breakdown of a reactive compound, showcasing the activity of the enzyme in living tissues. The effervescence observed is a visual indication of the reaction taking place.
