A chemist studies the elements in the image.
Based on the information, what type of element is Element X & Element Y?
Element X and Element Y are both metals.
Element X and Element Y are both metalloids.
Element X is a non-metal, and Element Y is a metalloid.
Element X is a metal, and Element Y is a non-metal.
If an element is:
Solid
Malleable
Shiny
High conductivity
What type of element would it likely be?
The element could be Ag (Gold) because Ag is a metal.
The element could be Sb (Antimony) because Ab is a metalloid
The element could be He (Helium) because He is a non-metal.
The element could be Ar (Argon) because Ar is a nonmetal.
If someone is looking at the Element Oxygen (O), they look at where it is located on the periodic table to determine it's properties.

A student puts pennies into separate containers. The image shows the results.
Which container showed a chemical change?
Container A because the penny got wet in the water.
Container B because bubbles formed in a liquid
Containers A and B because the penny was a precipitate.
Containers A and B because there was a change in heat.
A scientist mixes two clear liquids together. When the liquids are mixed, white solids form, and makes the clear liquids appear cloudy. (we did this last week on the lab day)
What observations indicate that a chemical change has occurred? Select two answers.
A solid appears
Both of the solutions are clear
The two solutions are combined
There is a color change
Both solutions are liquids
During the Sunset in a Bag experiment last week, we added Calcium Carbonate (the white pebble looking things) to water, and it became hot.
Did a chemical change happen, and How do you know a chemical change happened?
No, because a gas didn't form
Yes, because there was no change in color
Yes, because there was a change in temperature
No, because a solid was formed
A black iron chair is placed outdoors. Over time, the chair becomes coated with a red substance.
Which is the best explanation for the appearance of the red substance?
The red substance is a form of black iron that appears.
The red substance is a mixture of two substances in iron.
The red substance is the product of a chemical change.
The red substance formed when the black substance melted.
Which of the following is NOT a chemical change?
You roasting a marshmallow at a campfire
Ms Cooley writing on her whiteboard
Miss Melton lighting elements on fire in the lab

Way back during the Solid, Liquid and Gas unit, you observed the inflating of a balloon using chemical reactions. A balloon was filled with baking soda, and then fastened onto a bottle that already had some vinegar in it. When the two substances mixed together, the balloon inflated, and your teacher allowed you to touch the glass bottle to observe what happened.
