Is vapour a chemical reaction?
Vapor is not a chemical reaction itself. It is the gaseous state of a substance that was previously in liquid or solid form. The process of creating vapor from a liquid or solid can involve a physical change (such as evaporation) rather than a chemical reaction.
What forms can reaction products take?
Products of a chemical reaction are solids, liquids or gaseous.
What does the symbol g represent in a chemical equation?
The symbol (g) is gas (in a chemical reaction) or gram.
When a substance changes from one state to another do the chemical properties change?
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
What is the chemical difference between the gaseous and liquid state of the same substance?
Any chemical difference exist.
Is there a chemical difference between the gaseous state and liquid state of a substance?
Phase has nothing to do with chemical composition.
What kind of reaction is when you light a match?
its a chemical reaction. in addition to heat and light, a new gaseous substances are formed
When wood is burned heat ash and smoke are produced describe this reaction and explain what type of change is occurring?
Burning wood is a chemical reaction where the wood combines with oxygen in the air to produce heat, ash (carbon residue), and smoke (gaseous byproducts). This is a chemical change because the wood undergoes a chemical reaction to form new substances.
When ethyl alcohol evaporates is it a chemical or physical change?
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
Is Gaseous ammonia a pure substance?
Yes, gaseous ammonia is a pure substance. As long as it consists of only ammonia molecules, it is considered a pure substance because it has a constant composition and distinct chemical properties.
Can a liquid substance diffuse in another liquid substance a gaseous in liquid a gaseous in gaseous?
Yes, all of them.
When zinc is added to sulphuric acid what gas produced?
The gaseous product in this reaction is 'hydrogen' and the salt is zinc sulfate.
