What else can I help you with?
Is evaporation of dry ice a decomposition reaction?
No, the evaporation of dry ice is a physical change, not a decomposition reaction. Dry ice is solid carbon dioxide, and when it evaporates, it changes directly from a solid to a gas without undergoing a chemical reaction.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
How would you write the equation to show water evaporation?
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
Which in the following events is not a common sign that a chemical change taken place?
For example melting, boiling, evaporation, transformation in powder are not signs of a chemical reaction.
What are the uses of round bottle flask?
Examples are: distillation, chemical reaction with reactants in solution at high temperature, evaporation.
Is gasoline being evaporated a chemical reaction?
No. Evaporation is a physical process.
Is the drying of wet laundry a chemical reaction?
No, it is a physical process - water evaporation.
Is evaporation of water from a lake a chemical reaction?
No, evaporation of water from a lake is a physical process, not a chemical reaction. It involves the transformation of water from a liquid to a gas without any change in the chemical composition of water molecules.
How does ethanol evaporation affect the efficiency of a chemical reaction?
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
Is evaporation a chemical or physical reaction?
Evaporation represents the uptake of energy by the liquid that results in a physical change. (phase or state of matter)
Evaporation and condensation are what reaction?
Not chemical reactions, but change of phases
Is evaporation of dry ice a decomposition reaction?
No, the evaporation of dry ice is a physical change, not a decomposition reaction. Dry ice is solid carbon dioxide, and when it evaporates, it changes directly from a solid to a gas without undergoing a chemical reaction.
When liquid becomes a water vapor is that a chemical reaction?
no. chemical reaction requires a new substance to be created
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.
