Q: Answer the following question given this paragraph: Ice is an example of solid matter. A solid is matter that has a fixed volume and a fixed shape. Figure below shows examples of matter that are usually solids under Earth conditions. In the figure, salt and cellulose are examples of crystalline solids. The particles of crystalline solids are arranged in a regular repeating pattern. The steaks and candle wax are examples of amorphous ("shapeless") solids. Their particles have no definite pattern. Q: What is the name for a matter that has a fixed volume and a fixed shape? A:

OPTIONS:
- gas
- stable
- liquid
- solid

A: solid

input: OPTIONS:
- gasoline
- cyanide
- TNT
- gunpowder Now, answer this question: Answer the following question given this paragraph: Nitrates, salts of nitric acid, form when metals, oxides, hydroxides, or carbonates react with nitric acid. Most nitrates are soluble in water; indeed, one of the significant uses of nitric acid is to prepare soluble metal nitrates. Nitric acid finds extensive use in the laboratory and in chemical industries as a strong acid and strong oxidizing agent. It is important in the manufacture of explosives, dyes, plastics, and drugs. Salts of nitric acid (nitrates) are valuable as fertilizers. Gunpowder is a mixture of potassium nitrate, sulfur, and charcoal. The reaction of N2O3 with water gives a pale blue solution of nitrous acid, HNO2. However, HNO2 (shown in Figure 18.51) is easier to prepare by the addition of an acid to a solution of nitrite; nitrous acid is a weak acid, so the nitrite ion is basic in aqueous solution: NO 2 (aq) + H 3 O +(aq) HNO 2(aq) + H 2 O(l) Nitrous acid is very unstable and exists only in solution. It disproportionates slowly at room temperature (rapidly when heated) into nitric acid and nitric oxide. Nitrous acid is an active oxidizing agent with strong reducing agents, and strong oxidizing agents oxidize it to nitric acid. Q: What is a mixture of potassium nitrate, sulfur, and charcoal? A:
A:
output: gunpowder

Answer the following question given this paragraph: The amount of kinetic energy in a moving object depends directly on its mass and velocity. It can be calculated with the equation: . Q: The amount of kinetic energy in a moving object depends directly on what two factors? A:

OPTIONS:
- revolution and velocity
- inertia and momentum
- gravity and weight
- mass and velocity

Answer: mass and velocity

Problem: OPTIONS:
- shield
- rib
- fault
- groin
Q: Answer the following question given this paragraph: Longshore drift can erode the sediment from a beach. To keep this from happening, people may build a series of groins. A groin is wall of rocks or concrete that juts out into the ocean perpendicular to the shore. It stops waves from moving right along the beach. This stops the sand on the upcurrent side and reduces beach erosion. You can see how groins work in Figure below . Q: A wall of rocks or concrete that juts out into the ocean perpendicular to the shore is called? A:
Answer: groin

Problem:OPTIONS:
- bronchioles
- trachea
- bronchi
- alveoli

Answer the following question given this paragraph: Pulmonary gas exchange is the exchange of gases between inhaled air and the blood. It occurs in the alveoli of the lungs. Alveoli (singular, alveolus) are grape-like clusters surrounded by networks of thin-walled pulmonary capillaries. After you inhale, there is a greater concentration of oxygen in the alveoli than in the blood of the pulmonary capillaries, so oxygen diffuses from the alveoli into the blood across the capillaries (see Figure below ). Carbon dioxide, in contrast, is more concentrated in the blood of the pulmonary capillaries than in the alveoli, so it diffuses in the opposite direction. Q: In what part of the lungs is pulmonary gas exchanged? A:
****
A: alveoli

Problem:OPTIONS:
- soluble
- Sugar
- carbohydrates
- dietary

Answer the following question given this paragraph: Many other salts are important in the body. For example, bile salts produced by the liver help break apart dietary fats, and calcium phosphate salts form the mineral portion of teeth and bones. Q: Bile salts produced by the liver assist in breaking apart what kind of fats? A:
****
A:
dietary
