Is it true that a physical change and a chemical are exactly alike?
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Is it true that a chemical change is also called a chemical reaction?
Yes
Why isn't a change in mass an indicator of chemical change?
Neither a chemical nor a physical change results in a change in mass. According to the law of conservation of matter/mass, matter can neither be created nor destroyed. This law holds true for physical and chemical changes.
Is this statement true or false A chemical change is also called a chemical reaction.?
True. A chemical change refers to a process where substances transform into new substances through a chemical reaction, involving the breaking and forming of bonds. This transformation alters the chemical properties of the original substances.
Is it true that a physical change and a chemical are exactly alike?
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
A chemical reaction causes a chemical change true or false?
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
A change in which one or more substances combine or break apart to form new substances?
chemical change
What is the True indication of a chemical change?
A change in color
During a chemical change the form of a substance is altered but not its identity true or false?
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Chemical properties observed only when a substance undergoes a chemical change a true bfalse?
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
In examples of chemical changes the odor of sour milk indicates a chemical change has taken place true or false?
True. The souring of milk is a chemical change caused by the breakdown of lactose sugars into lactic acid by bacteria. The change in odor is a result of this chemical reaction.
What is the only true indication of a chemical change?
A change in color
Is it true that a chemical change is also called a chemical reaction?
Yes
Is it true or false for A Change In State Is A Physical Change?
True. A change in state, such as from solid to liquid or gas, is a physical change because the substance's chemical composition remains the same and only its physical properties, like shape or state, change.
Does physical and mechanical change the same as physical and chemical change?
no its not true
What is true for a physical change as well as a chemical change?
A chemical has changed appearance in both a physical and chemical change. It cannot stay the same or it wouldn't have changed.
