Sample QuestionTwo chemists are designing instant hot and cold packs for a sports medicine supply company. Their design uses chemicals that react with water to either heat up or cool down the water inside the packs. They are investigating the reaction of ammonium chloride with water to determine whether it is exothermic or endothermic. Chemist A read a study done recently by the National Institute for Standards and Testing, which reported that 27.6 kilojoules of energy are absorbed by 100 grams of ammonium chloride when it is mixed with water. Chemist B measured the temperature of the water in which the reaction takes place before and after the reaction. The results are displayed in the table. Question: Does Chemist B's results support or contradict the evidence reported by Chemist A? You may use the calculator

About 2.7 billion years ago, the lower atmosphere had almost no oxygen. It was long before plants existed to produce oxygen. However, in the upper atmosphere, oxygen can be produced when carbon dioxide is split by sunlight into carbon monoxide and oxygen.
Scientists examined 11 ancient micrometeorites, all older than 2.7 billion years old, and discovered that most of them had once been particles of iron mixed with oxygen. In order for that to happen, there had to be almost as much oxygen in the upper atmosphere as there is now. The scientists say that the new information about the upper atmosphere does not change what they know about the lower atmosphere.
Question: Which statement accurately summarizes the passage?

Dissolved carbon dioxide gas (CO2 ) creates carbonic acid in ocean water. Rising ocean acidity levels may harm marine life. For example, high acid levels may cause hearing loss. Scientists conducted an investigation to study the effect of increased acidity on fish hearing.
A group of fertilized fish eggs from the same parents were divided into four different aquariums, each with a different pressure of CO2 . One tank contained the normal atmospheric conditions of 390 microatmospheres of CO2 . The other tanks contained 600, 700, and 900 microatmospheres of CO2 , respectively. The same number of eggs was placed into each aquarium. The eggs hatched and the fish lived in these aquariums until testing.
To prepare for the experiment, one fish was placed into an aquarium containing the same CO2 pressure in which it was raised. The fish's position was recorded every 5 seconds for 2 minutes. Then sounds from a predatory fish were played from an underwater speaker at one end of the aquarium at a volume that was only audible to the fish when swimming near the speaker. The fish's position was again recorded every 5 seconds for 2 minutes. Trials were repeated with fish from each tank.
The study showed that fish raised in elevated CO2 levels did not avoid the sounds of the predator fish. They spent approximately the same proportion of time at the speaker end of the aquarium before and after the sounds of the predator fish were played. However, the fish from the aquarium with the normal atmospheric CO2 pressure avoided the speaker end of the aquarium after the predator sounds were played.
Question: What are the independent and dependent variables in the investigation?
