Introduction to Mass
Anything that has mass and takes up space
What is Matter?
This is a liquid that is known to have more solute dissolved in it.
What is concentrated?
The tiny central core of an atom
What is a nucleus?
A base that separates completely into ions when dissolved in water.
What is a strong base?
The part of the atom that has no charge and is neutral
What are neutrons
This is the temperature at which a substance boils
What is a boiling point?
A solution in which as much solute as possible is dissolved in a solvent.
What is a saturated solution?
The electrons that are the farthest away from the nucleus of an atom and are involved in chemical reactions.
What are valance electrons?
The system breaks down food into simpler substances used for food.
How foods are changed by the digestive system
This happens when atoms share electrons unequally
What is a polar bond?
This is a change in the state of matter where substances combine or break apart to form new substances.
What is a chemical change?
litmus paper and red cabbage juice powder
What are examples of indicators?
An atom or group of atoms that has become electrically charged.
What is an ion?
acid: sour taste
base: bitter taste
How can you tell if a food may contain an acid or a base as one of its ingredients?
This consists of molecules having covalently bonded atoms
What is a molecular compound
This is a substance made of two or more elements that are chemically combined.
What is a compound?
An ionic compound, it forms from the neutralization of an acid with a base
What is salt?
The type of bond that is made when two atoms share electrons.
What is a covalent bond?
A measurement of how well a solute can dissolve in a solvent at a given temperature.
What is solubility?
Tiny, negatively charged, high energy particles that move around outside the nucleus of an atom
What is an electron?
length x width x height
What is the calculation for volume?
A gas produced when an acid reacts with a carbonate
What is carbon dioxide?
This property of a material can be found when scratching it
What is hardness?
The gas that is produced when an acid reacts with a carbonate.
What is carbon dioxide?
Part of the atom that has no charge and is neutral
What are neutrons
