*Question*
Answer the following question given this paragraph: Fructose, a sugar found in fruit, contains only carbon, oxygen, and hydrogen. It is used in ice cream to prevent a sandy texture. Complete combustion of 32.4 mg of fructose in oxygen produced 47.6 mg of CO2 and 19.4 mg of H2O. What is the empirical formula of fructose? 11. Coniine, the primary toxin in hemlock, contains only carbon, nitrogen, and hydrogen. When ingested, it causes paralysis and eventual death. Complete combustion of 28.7 mg of coniine produced 79.4 mg of CO2 and 34.4 mg of H2O. What is the empirical formula of the coniine? 12. Copper and tin alloys (bronzes) with a high arsenic content were presumably used by Bronze Age metallurgists because bronze produced from arsenic-rich ores had superior casting and working properties. The compositions of some representative bronzes of this type are as follows:. Q: How can you prevent your ice cream from getting a sandy texture? Choices: - by using lowfat milk - by adding oil - by adding salt - by using fructose A:
**Answer**
by using fructose

Answer the following question given this paragraph: The Figure below shows the direction of the current that is generated by a moving magnet. If the magnet is moved back and forth repeatedly, the current keeps changing direction. In other words, alternating current (AC) is produced. Alternating current is electric current that keeps reversing direction. Q: What is the term for electric current that keeps reversing direction? Choices: - direct current - AC/DC - magnetic current - alternating current A:
**Answer**
alternating current

*Question*
Answer the following question given this paragraph: When current flows in just one direction, it is called direct current (DC) . The diagram below shows how direct current flows through a simple circuit. An example of direct current is the current that flows through a battery-powered flashlight. In addition to batteries, solar cells and fuel cells can also provide direct current. Q: What kind of current flows in just one direction? Choices: - physical current - slow current - Alternating current - direct current A:
**Answer**
direct current
