What else can I help you with?
What fuel is used in matches?
The fuel used in matches is typically red phosphorus or sulfur mixed with an oxidizing agent such as potassium chlorate. When struck against a rough surface, the match ignites and produces a flame due to the combustion reaction between the fuel and the oxidizing agent.
What is the main difference between a fuel cell and a voltaic cell?
A fuel cell generates electricity from a chemical reaction between a fuel source and an oxidizing agent, without requiring any recharging. A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
Is combustion a redox reaction?
Yes, combustion is a redox reaction because it involves the transfer of electrons between reactants, resulting in the oxidation of the fuel and reduction of the oxidizing agent.
What is the relationship between a fuel cell and a primary cell?
Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.
What is a type of cell where chemical energy is converted into electrical energy?
A type of cell where chemical energy is converted into electrical energy is a fuel cell. Fuel cells generate electricity through an electrochemical reaction between a fuel (such as hydrogen or natural gas) and an oxidizing agent (typically oxygen).
Is propane an oxidizing agent?
No it is not. Propane can be used as fuel during oxidation reaction however it is not an oxidizing agent. In a redox reaction such as combustion, propane acts as a reducing agent. Common agents are O2 and O3.
Is oxygen the oxidizing agent in combustion and the reducing agent in corrosion?
Yes, in combustion, oxygen acts as the oxidizing agent because it gains electrons from the fuel being burned. In corrosion, however, oxygen acts as the oxidizing agent as it accepts electrons from the metal, causing it to corrode or rust.

A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
What are the constituents of fire?
The three contituents of fire include oxidizing agent, heat and fuel. The oxidizing agent is usually oxygen in most cases. A fire occurs when the three elements are present in the right proportion.
Is combustion a redox reaction?
Yes, combustion is a redox reaction because it involves the transfer of electrons between reactants, resulting in the oxidation of the fuel and reduction of the oxidizing agent.
Can rockets be launched in vacuum?
Yes. Rockets have both a fuel and an oxidizing agent, so they don't need air.
What is the relationship between a fuel cell and a primary cell?
Both fuel cells and primary cells are devices that convert chemical energy into electrical energy. The main difference is that primary cells use stored chemical energy in the form of a non-rechargeable chemical reaction, while fuel cells continuously receive fuel and an oxidizing agent to generate electricity through a controlled chemical reaction.
Do substance actually burn in combustion reactions?
The fuel burns, oxygen or some other oxidizing agent, isn't burning, it supports the combustion of the fuel.
What is a type of cell where chemical energy is converted into electrical energy?
A type of cell where chemical energy is converted into electrical energy is a fuel cell. Fuel cells generate electricity through an electrochemical reaction between a fuel (such as hydrogen or natural gas) and an oxidizing agent (typically oxygen).
How does oxygen supports burning?
Oxygen is an oxidizing element, in that it accepts electrons. Oxidizing elements are essential in combustion reactions as reactants. Once the amount of oxygen runs out, the reaction stops, therefore it supports burning by allowing the reaction to carry forward.
Is a fuel cell a secondary cell?
No, a fuel cell is not considered a secondary cell. Fuel cells generate electricity through a chemical reaction involving a fuel source and an oxidizing agent, without the need for recharging like secondary cells, such as batteries.
