Answer the following question given this paragraph: You already know that a sour taste is one property of acids. ( Warning : Never taste an unknown substance to see whether it is an acid!) Acids have certain other properties as well. For example, acids can conduct electricity when dissolved in water because they consist of charged particles in solution. (Electric current is a flow of charged particles. ) Acids can also react with metals, and when they do they produce hydrogen gas. An example of this type of reaction is hydrochloric acid reacting with the metal zinc (Zn). The reaction is pictured in the Figure below . It can be represented by the chemical equation:. Q: Acids can also react with metals, and when they do they produce what? A:
OPTIONS:
- alloys
- potassium gas
- rust
- hydrogen gas

Answer: hydrogen gas

Problem: OPTIONS:
- water quality
- all of the above
- natural events
- human activity
Q: Answer the following question given this paragraph: Natural events, like storms, volcanic eruptions and earthquakes can cause major changes in water quality. But human-caused contaminants have a much greater impact on the quality of the water supply. Water is considered polluted either when it does not support a human use, like clean drinking water, or a use for other animals and plants. The overgrowth of algae, known as an algal bloom , can result from the runoff of fertilizer into bodies of water. This excess of nutrients allows the algae to grow beyond control, bring harm to the rest of the ecosystem. Q: What has a bigger impact on water quality, natural events or human activity? A:
Answer:
human activity
