Answer the following question given this paragraph: When the ore leaves the mine, it is not yet a useful material ( Figure below ). Most ores are a combination of metal and other elements. The rocks are full of valuable minerals. They also contain rock that isn't valuable, which is called waste rock. The valuable minerals must be separated from the waste rock. Q: Along with other elements, most ores are made of what? A:

OPTIONS:
- coal
- crystals
- sodium
- metal

Answer: metal

Answer the following question given this paragraph: The extent to which a substance may be dissolved in water, or any solvent, is quantitatively expressed as its solubility, defined as the maximum concentration of a substance that can be achieved under specified conditions. Substances with relatively large solubilities are said to be soluble. A substance will precipitate when solution conditions are such that its concentration exceeds its solubility. Substances with relatively low solubilities are said to be insoluble, and these are the substances that readily precipitate from solution. More information on these important concepts is provided in the text chapter on solutions. For purposes of predicting the identities of solids formed by precipitation reactions, one may simply refer to patterns of solubility that have been observed for many ionic compounds (Table 4.1). Solubilities of Common Ionic Compounds in Water Soluble compounds contain group 1 metal cations (Li+, Na+, K+, Rb+, and Cs+). Q: The extent to which a substance may be dissolved in water or another solvent is known as what? A:
OPTIONS:
- humidity
- flexibility
- turbidity
- solubility
solubility

Answer the following question given this paragraph: Fossil fuels are made from plants and animals that lived hundreds of millions of years ago. The plants and animals died. Their remains settled onto the ground and at the bottom of the sea. Layer upon layer of organic material was laid down. Eventually, the layers were buried very deeply. They experienced intense heat and pressure. Over millions of years, the organic material turned into fossil fuels. Q: Fossil fuels are made out of what two objects? A:
OPTIONS:
- gases and animals
- plants and water
- soil and animals
- plants and animals

Answer: plants and animals
