Chemical/Physical Properties
A property observed without changing the identity of the substance.
What is a physical property?
Shape change, size change, and state change.
What is reactants?
Plants power photosynthesis through this bright light.
What is the sun?
Cellular respiration is done by both of these kinds of organisms.
A property observed by changing the identity of the substance.
What is a chemical property?
When one or more substances transform into new substances.
What is a chemical reaction?
In a chemical equation, these are the newly formed substances.
What is products?
Alongside the food that they make, plants also make this molecule so that animals can breathe.
What is oxygen?
The main goal of cellular respiration is for our cells to turn food into this.
What is energy?
The color of the car is red.
What is physical property?
An example of this is when vinegar and baking soda mix and the solution forms bubbles.
What is a chemical change/reaction?
Matter cannot be created or destroyed, it only changes form. Total mass is conserved.
What is the law of conservation of matter?
Animals breathe oxygen and eat glucose for respiration, but plants receive their oxygen and glucose through a different process.
What is photosynthesis?
The piece of wood catches fire very easily; therefore, it is flammable.
What is chemical property?
An example of this is when a water bottle is left out in the cold snow to freeze.
What is a physical change?
This law states that the total number of atoms in the reactants must equal the total number of atoms in the products
What is the law of conservation of matter?
Plants power photosynthesis through this special structure inside their cells.
What are chloroplasts?
The special cell structure responsible for cellular respiration.
What is the mitochondria?
Oil is less dense than water.
What is physical property?
Gas formation, color change, temperature change, light and heat, and formation of a precipitate.
What are the 5 signs of a chemical reaction?
You can determine whether the following equation follows the law of conservation by performing this task. 2H2 + O2 --> 2H2O
What is counting the atoms?
Plants collect carbon dioxide through these tiny openings in their leaves.
What are stomata?
This is what ATP stands for.
What is adenosine triphosphate?
