How does a match store chemical energy?
A match stores chemical energy through the chemical reactions that occur when it is struck against a rough surface, igniting the match head. The match head contains chemicals like sulfur, phosphorus, and potassium chlorate, which react to produce heat and light.
What happen when potassium chlorate is heated?
It would decompose and turn molten. But be careful when you are doing it. Molten potassium chlorate is very nasty stuff. Spill it onto your skin, and it would leave a terrible burn. Potassium chlorate decomposes into oxygen, and when something that could burn, such as a gummy bear, is added to it, it rapidly combusts, driving the decomposition forward. If you spill molten potassium chlorate, you could think of the table, floor, your clothes, your skin, as another gummy bear. So be cautious when working with it.
How can the rate of thermal decomposition of potassium chlorate be increased?
The rate of thermal decomposition of potassium chlorate can be increased by adding a catalyst, such as manganese dioxide, to lower the activation energy required for the reaction to occur. Increasing the temperature can also accelerate the rate of decomposition by supplying more energy to break the bonds in the compound.
Is potassium chlorate heated reversible?
Yes, when potassium chlorate (KClO3) is heated, it decomposes into potassium chloride (KCl) and oxygen gas (O2) through a reversible reaction. However, the reverse reaction of recombining potassium chloride and oxygen gas to form potassium chlorate is not spontaneous and typically requires additional energy input.
In heating the mixture of potassium chlorate and manganese dioxide what is the role of the manganese dioxide?
Manganese dioxide acts as a catalyst in the reaction, facilitating the decomposition of potassium chlorate into potassium chloride and oxygen gas. Manganese dioxide lowers the activation energy required for the reaction to occur, making the process more efficient and accelerating the release of oxygen gas.
Can potassium chlorate react with glucose?
Yes, potassium chlorate can react with glucose. When heated, potassium chlorate can oxidize glucose, leading to the release of energy in the form of heat, light, and gas. This reaction is highly exothermic and can even be explosive under certain conditions.
What reaction happens when we ignite a match stick?
That depends on whether you are considering the work done to overcome the force of static friction between the match head and the striking paper. Other than that, as I understand it, after you have heated part of the chemical compound on the match head sufficiently so that it combusts, the heat it outputs then affects the chemicals in close proximity heating them to the point of combustion. I'm not sure you could consider that chemical reaction to be work done, but you could argue it outputs energy.
How do you know why thermal energy by burning matchstick?
When a matchstick is burned, the thermal energy is released as a result of the chemical reaction between the match head (containing sulfur and potassium chlorate) and the striking surface (containing red phosphorus). This reaction generates heat energy, causing the matchstick to ignite and produce a flame.

How do you balance potassium chlorate when heated yields potassium chloride oxygen gas?
The balanced chemical equation for this reaction is: 2 KClO3 (s) → 2 KCl (s) + 3 O2 (g) This means that when two moles of potassium chlorate are heated, it will decompose to yield two moles of potassium chloride and three moles of oxygen gas.
Is any relationship between potassium and phosphorus?
Potassium and phosphorus are both essential minerals for the body, but they do not have a direct relationship in terms of function. However, they both play important roles in various physiological processes such as energy production, muscle function, and bone health. Maintaining a balance of these minerals in the body is crucial for overall health.
Phytin equals macronutrient where phosphorus is most found in food?
Phytin is an insoluble salt of potassium, magnesium and calcium. It is a major storage form of phosphate and macronutrient minerals in seeds. The macronutrient minerals in plants include: carbon, hydrogen, oxygen, potassium, nitrogen, phosphorus, magnesium, calcium and sulfur. Phosphorus is a component of the nucleic acid structure and is important in cell division, new tissue development and energy transformation in the plant.
What minaral salts contain phosphorus?
Mineral salts that contain phosphorus include calcium phosphate, sodium phosphate, and potassium phosphate. These salts are essential for various biological processes in the body including bone formation, energy production, and cell signaling.
