What else can I help you with?
When gas burns you can tell its a chemical change because?
it is a completely new object.
How does LPG gas burning on gas stove involve chemical and physical changes?
When LPG gas burns on a gas stove, it undergoes a chemical change as it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor. This is a combustion reaction. The physical change involved is the change in state of the gas from a liquid to a gaseous form as it is released from the cylinder and then burns.
Is gas burning in an engine a chemical change?
Of course, it is a chemical change.
Gas weuse in the kitchen is LPG In the cylinder it exist as a liquidWhen it comes out from the cylinder it becomes agaschange-athen it burns change-bWhat type of change is change-a physical or chmical?
Change-a (LPG changing from liquid to gas) is a physical change. It does not involve any chemical reactions, as the molecules of LPG remain the same as it transitions between its liquid and gas states.
Is a gas stove a chemical reaction?
Burning a fuel is a chemical change. Two or more substances are combined and new substances are produced with different properties than the original substances. In other words the gas and oxygen in the air are combined to form carbon dioxide and smoke.
When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Which physical and chemical change occur when LPG comes out of the cylinder and burns?
When LPG comes out of the cylinder, it changes from a liquid to a gas which is a physical change. When it burns, it undergoes a chemical change where it reacts with oxygen to produce heat, light, carbon dioxide, and water vapor.
Is using gas in an engine a chemical change?
Yes, it is. It's also a physical change because it changes its phase from liquid to gas.
An example of a substance that can be decomposed by a chemical change is?
Wood. When wood burns, it undergoes a chemical change that breaks it down into ash and gas, releasing energy in the process. This decomposition by fire is a chemical change, transforming the wood into different substances.
What example of changing a substance is an example of what?
iodine'(solid) can sublime to gas. also so does camphor Sublimation is a physical change, not a chemical change. Any substance that burns demonstrates a chemical change called combustion.
Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
Is Natural gas burns a chemical or physical property?
The burning of natural gas is a chemical property because it involves a chemical reaction. When natural gas (methane) reacts with oxygen in the air, it produces carbon dioxide, water, and heat energy. This is a chemical change as new substances are formed.
