Answer the following question given this paragraph: It may seem as though burning destroys matter, but the same amount, or mass, of matter still exists after a campfire as before. Look at the sketch in Figure below . It shows that when wood burns, it combines with oxygen and changes not only to ashes but also to carbon dioxide and water vapor. The gases float off into the air, leaving behind just the ashes. Suppose you had measured the mass of the wood before it burned and the mass of the ashes after it burned. Also suppose you had been able to measure the oxygen used by the fire and the gases produced by the fire. What would you find? The total mass of matter after the fire would be the same as the total mass of matter before the fire. Q: It may seem as though burning destroys matter, but the same amount of what, still exists after a campfire as before? A:
****
A: mass

Answer the following question given this paragraph: A series of chemical reactions where an initial amount of copper reacts with nitric acid, goes into solution, and disappears. Then a series of reactions proceed, only to have the copper metal recovered. The copper cycle is a good illustration of how mass is conserved in a given chemical reaction. Q: The cycle of copper reacting is a good example of what principle? A:
OPTIONS:
- law of inertia
- conservation of energy
- conservation of momentum
- conservation of mass
conservation of mass

Answer the following question given this paragraph: Some animals communicate with scent. They release chemicals that other animals of their species can smell or detect in some other way. Ants release many different chemicals. Other ants detect the chemicals with their antennae. This explains how ants are able to work together. The different chemicals that ants produce have different meanings. Some of the chemicals signal to all of the ants in a group to come together. Other chemicals warn of danger. Still other chemicals mark trails to food sources. When an ant finds food, it marks the trail back to the nest by leaving behind a chemical on the ground. Other ants follow the chemical trail to the food. Q: What part of the body do ants use to detect chemicals? A:
OPTIONS:
- thorax
- fins
- eyes
- antennae

Answer: antennae

OPTIONS:
- heavy roots
- fat roots
- no roots
