When sodium reacts with water is it a chemical or a physical change?
It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.NaOH + H2O --> Na+ + OH-The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.
How is a volcano a rapid change?
A volcano is a rapid change because it can go from a state of dormancy to eruption very quickly, often with little warning. The eruption itself can cause immediate and widespread changes to the surrounding environment, affecting landscapes, ecosystems, and communities in a short period of time.
When cesium metal reacts explosively with water does it go through a physical change or a chemical change?
The reaction between cesium metal and water is a chemical change because it involves the breaking and forming of chemical bonds to create new substances (cesium hydroxide and hydrogen gas). The explosive nature of the reaction is due to the rapid release of energy during this chemical transformation.
What type of change takes place when you mix sugar in water?
Yes sugar in water is a temporary change as 1) It is reversible as when we evaporate the solution/mixture it-the sugar remains behind. 2)Energy is niether evovled nor absorbed during this change
What is the difference between a reversible reaction and a reaction that goes to completion?
The reactions in which the products can recombine to form reactants are called reversible reactions. These reactions never go to completion. They are represented by a double arrow between reactants and products.
What happens when a chemical change does not go through completion?
The chemical reaction is interrupted.
What happens when a chemical change does not go to completion?
When a chemical change does not go to completion, some reactants may remain after the reaction has reached equilibrium. This can result in a mixture of both reactants and products in varying amounts. The extent to which a reaction goes to completion depends on factors such as reaction conditions, reactant concentrations, and the presence of catalysts.
Does a change in substances and properties go with physical change?
no, if it's a substance change then it's a chemical change. If it were a physical change then it would be the same substance

When a can is crushed does it go through a physical change or a chemical change?
Yes, a crushed can has chemical properties. They are the same as those of the can before crushing. Crushing a can is a physical reaction and not a chemical one. For instance, if a soup can is made of steel, the steel can be chemically attacked by something like sulfuric acid. And this is true whether the can is crushed or not.
