Zinc and lead are more reactive than copper, according to the reactivity series. This means they have a greater tendency to form compounds, thus displacing copper from its compounds in reactions.

This reaction is a displacement reaction because iron displaces copper from copper sulfate solution, leading to the formation of iron sulfate and elemental copper.

Endothermic reactions absorb energy from the surroundings and typically feel cold to the touch, while exothermic reactions release energy into the surroundings, often in the form of heat, and feel warm or hot.

Endothermic reactions are those in which energy is absorbed from the surroundings. This can occur in the form of heat, light, or electricity, as seen in processes like the decomposition of silver chloride in sunlight.

In black and white photography, light-sensitive silver halide crystals, such as silver chloride, undergo decomposition when exposed to light, forming metallic silver particles that create the photographic image.

White silver chloride turns grey in sunlight due to the decomposition of silver chloride into silver and chlorine by light energy.

Glucose is metabolized in the cells through a series of biochemical reactions, primarily aerobic cellular respiration. This process involves the oxidation of glucose in the presence of oxygen, resulting in the release of energy that is used to fuel various ...

Carbohydrates are broken down into glucose during digestion. Glucose then combines with oxygen in the cells through cellular respiration to produce energy in the form of ATP (adenosine triphosphate).

Food is broken down into simpler substances during digestion through processes such as mechanical chewing and enzymatic reactions in the stomach and intestines.

The main source of energy for the human body is carbohydrates. When consumed, carbohydrates are broken down into glucose, which cells use for energy through cellular respiration.
