Is natural gas burning on a stove positive or negative?
positive. The gas in a piston (defined as the system) is warmed and absorbs 670J of heat. The expansion performs 342J of work on the surroundings.
Is lighting a gas stove an exothermic reaction?
Brushing your teeth, washing your hair, and lighting your stove are all examples of exothermic reactions.
Is a stove endothermic?
endothermic – you must put a pan of water on the stove and give it heat in order to get water to boil. Because you are adding heat/energy, the reaction is endothermic. exothermic – when you burn something, it feels hot to you because it is giving off heat into the surroundings.
Why is lighting a stove exothermic?
Energy is absorbed from the pan to cook an egg on your stove. Examples of Exothermic Reactions: Lighting a fire to burn brush releases heat. The condensation of water vapor into rain expels heat.
Is a gas burning an endothermic reaction?
Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
Is burning endothermic or exothermic?
exothermic reaction Combustion also popularly known as burning is an exothermic reaction wherein there is a release of heat. Combustion reactions are also mainly redox chemical reactions involving an oxidant which is usually atmospheric oxygen.
Is Heating endothermic or exothermic?
endothermic process Heating is an endothermic process, but not a chemical reaction.
Why is burning of natural gas exothermic?
when methane (natural gas) reacts with oxygen, the result is carbon di-oxide and water, along with heat, hence making it an exothermic reaction.

What are 5 examples of endothermic reactions?
Endothermic Processes Melting ice cubes. Melting solid salts. Evaporating liquid water. Converting frost to water vapor (melting, boiling, and evaporation, in general, are endothermic processes.
What is burning of natural gas?
It is a combustion reaction as well as an exothermic reaction. When methane,CH4 (natural gas) reacts with oxygen, the result is carbon dioxide and water, along with heat, hence making it an exothermic reaction. CH4 + 2O2 → CO2 + 2H2O + Energy.
Which type of reaction is burning of natural gas and respiration?
Exothermic reactions Exothermic reactions: Burning of natural gas and Respiration.
Is burning of natural gas an endothermic reaction?
The correct answer is Exothermic. Explanation: The burning of natural gas produces heat, which is an example of an exothermic reaction. Exothermic reactions are also referred to as combustion reactions.
What is the combustion reaction of natural gas?
The main component of natural gas is the hydrocarbon called methane (CH4). You can see a methane flame in the Figure below. The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O.
Is combustion exothermic or endothermic?
