Q: Answer the following question given this paragraph: A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. A chemical change is also called a chemical reaction. Many complex chemical changes occur to produce the explosions of fireworks. An example of a simpler chemical change is the burning of methane. Methane is the main component of natural gas, which is burned in many home furnaces. During burning, methane combines with oxygen in the air to produce entirely different chemical substances, including the gases carbon dioxide and water vapor. You can watch some very colorful chemical changes occurring in the video at this URL:. Q: When matter changes into an entirely different substance with different chemical properties, what has occurred? A:

OPTIONS:
- mechanical change
- gaseous change
- physical change
- chemical change

A: chemical change

input: OPTIONS:
- invertebrate structure
- parasitic structure
- primordial structure
- vestigial structure Now, answer this question: Answer the following question given this paragraph: Some of the most interesting evidence for evolution comes from vestigial structures . These are body parts that are no longer used but are still present in modern organisms. Examples in humans include tail bones and the appendix. Q: What is the tail bone an example of? A:
A:
output: vestigial structure

Answer the following question given this paragraph: 2Al(s) + Fe2O3(s) 2Fe(s) + Al2O3(s) + heat to indicate that heat is one of the products. Chemical equations in which heat is shown as either a reactant or a product are called thermochemical equations. In this reaction, the system consists of aluminum, iron, and oxygen atoms; everything else, including the container, makes up the surroundings. During the reaction, so much heat is produced that the iron liquefies. Eventually, the system cools; the iron solidifies as heat is transferred to the surroundings. A process in which heat (q) is transferred from a system to its surroundings is described as exothermic. By convention, q < 0 for an exothermic reaction. Q: Chemical equations in which heat is shown as either a reactant or a product are called what? A:

OPTIONS:
- hydroelectric equations
- thorium equations
- feedstock equations
- thermochemical equations

Answer:
thermochemical equations
