Matter
This type of matter is made up of a single type of particle
What is an element?
A gram is used to measure....
What is mass?
Is rust an example of a chemical change?
What is YES? You cannot change rust back into the metal is was before; therefore, it is a chemical change.
Calculate the mass of a liquid with a density of 2.5 g/mL and a volume of 15mL.
What is 37.5 grams?
This is the amount of space an object takes up.
What is volume?
This is the smallest particles of an element
What is an atom?
When would I use a cm3 as opposed to an mL?
When measuring the volume of a solid?
Explain how water could be an example of a physical change.
What is freezing and melting water to and from ice is an example of a physical change?
The mass of chemical A is 4g and the mass of chemical B is 10g. If the two chemicals are mixed and a chemical reaction takes place, what is the mass of the end products?
What is 14 grams?
This is the measure of the amount of matter in a certain amount of space.
What is density?
Water is classified as an element, compound or mixture?
What is an compound (H20)
What is the equation for density?
Is Frying an egg a physical or chemical change?
What is a chemical change?
Matter is never destroyed or created, the mass that you begin with is always the same as the mass you will end with.
What is the law of conservation of mass?
Anything that has mass and takes up space
What is matter?
Gold is an example of this
What is an element?
If you had a rock and you put it in a beaker with 40 ml water. The water displaces to 100 ml, what was the volume of the rock?
What is 60mL?
Name the two indicators of a chemical change.
What are color changes, bubbles, and temperature changes?
Explain the difference between endothermic and exothermic reactions.
What is the difference between endothermic and exothermic is endothermic absorbs the heat and turns cold, exothermic releases the heat and turns warm/hot
These are the characteristics of an object and you use your senses to identify them.
What are PHYSICAL PROPERTIES?
This is made up of two or more kinds of matter that can be separated out.
What is a mixture?
If you have a rock with a mass of 120 grams. You place the rock in a beaker with 30ml, and the water displaces to 90 ml. What is the density of the rock?
What is is 2 g/ml3.
Why is bread rising a chemical change?
It's a chemical change because the yeast in the bread is converting carbohydrates into carbon dioxide gas
You put dry ice into water to create fog, the fog is produced and the reaction is over. This was a Physical Change. True or False
What is true?
A type of change where the substance stays the same, but size and shape may change.
