When a chemical change is in place does no new substance form?
No, a new substance is normally formed
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place explain?
When sugar is heated for a short time, it undergoes a physical change called caramelization. During this process, the sugar molecules break down and recombine into a new substance without changing the chemical composition of the sugar molecules. The result is the formation of a thick, colorless liquid substance known as caramel.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
If you mix to clear liquids together and bubbles for what type of change would this indicate?
It indicates a chemical reaction because it changes from one substance to another.
What stays the same in a physical change?
The chemical nature/identity of the substance stays the same when a physical change takes place.
What take place when a substance undergoes a chemical change?
an explosion (fact)
What is the definition chemical change?
Chemical ChangesAs opposed to a physical change, chemical changes are present when the substance undergoes a chemical reaction and produces a new substance. A chemical change is a chemical reaction that will always take place for there to be a chemical change. Signs that a reaction is taking place: Formation of gases (bubbles), Color change, production of heat or light, and the formation of a solid. a change in composition and characteristics of matter.new substance maybe formed.original substance and form may be lost.new color and shapeExamplesFermentationPhotosynthesisRusting nailSpoiling milkDigesting food
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
When a substance undergoes a phase change what occurs a particle change a chemical change a new substance is formed a physical change?
During a phase change, the substance transitions between different states of matter (solid, liquid, gas) without any change in the chemical composition of the particles involved. This means that there is no new substance formed and no chemical change taking place, it is solely a physical change.
When a chemical change is in place does no new substance form?
No, a new substance is normally formed
When a change makes a new substance you say a - has taken place?
A chemical reaction makes a new substance.
How does matter chemically change?
The chemical changes take place on moleculer space. A chemical change form (or) produce a new substance.
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.
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place explain?

What takes place when a substance undergoes a chemical change?
The following can indicate that a chemical change has taken place:Change of odor.Change of color.Change in temperature or energy, such as the production or loss of heat.Light, heat, or sound is given off.Formation of precipitate.
What does a substance changed into when chemical change take place?
The reactants are changed in products having new chemical composition.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
