What is the difference between the substances represented by the symbols Co and CO?

• They are two different ways to represent the element cobalt.

• One is the symbol for an element, and one is a formula for a compound.

• Co represents the element cobalt, and CO represents the element copper.

• They represent two substances, each made up of two elements.

Some students are testing rock samples they collected. If you wanted to test these rocks for calcite, what would you put in the bottle and what would you expect to happen if calcite is there?

• Put water in the bottle; if there is calcite, the rock will dissolve.

• Put salt water in the bottle; if there is calcite, the rock will turn a darker color.

• Put acid in the bottle; if there is calcite, the rock will fizz.

• Put liquid soap in the bottle; if there is calcite, the liquid will form a dome on the rock.

A student dissolved 20 g of salt in a cup of water. She left the cup uncovered in an area where nobody could touch it. When she returned to the cup 10 days later, she found that all the water was gone, and there were crystals in the bottom of the cup. What is the best conclusion, based on her observations?

• The water evaporated, and there is 20 g of salt in the cup.

• The water and some salt evaporated, but some salt is left in the cup.

• There was a chemical reaction, and a new solid was left behind.

• The water and salt separated and then the water evaporated, but there is no way to know what is left in the cup.
