What else can I help you with?
Is ice melting. A chemical reaction?
No, it's a physical reaction because it is still water just in a different form.
Is the reaction between aluminum and copper chloride a physical or chemical change?
The reaction between aluminum and copper chloride is a chemical change. During the reaction, a chemical reaction occurs resulting in the formation of new substances with different properties than the original reactants. This is different from a physical change where substances maintain their original properties.
When substances are formed that are different from the starting substances has physical change occurred?
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
Freezing involves a chemical reaction?
No, freezing involves phase change, which is a physical change. There is no chemical reaction, as the basic chemistry is unchanged it is still the same material in a different physical state.
Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.
Is a change that produces a new element a physical change?
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
What is made from a chemical reaction?
In a chemical reaction something new is created. A chemical change is inreversible where as a physical change is. In a physical change nothing new is formed.
Is magnesium plus oxygen a chemical or physical change?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
Is water a chemical reaction or a physical reaction?
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Why is a phase change a physical change and NOT a chemical change?
Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
What happens to the chemical and physical properties of a substance formed in a chemical reaction?
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
