Q: 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? A:

OPTIONS:
- by using lowfat milk
- by adding oil
- by adding salt
- by using fructose

A: by using fructose

Answer the following question given this paragraph: Salts Recall that salts are formed when ions form ionic bonds. In these reactions, one atom gives up one or more electrons, and thus becomes positively charged, whereas the other accepts one or more electrons and becomes negatively charged. You can now define a salt as a substance that, when dissolved in water, dissociates into ions other than H+ or OH. This fact is important in distinguishing salts from acids and bases, discussed next. A typical salt, NaCl, dissociates completely in water (Figure 2.15). The positive and negative regions on the water molecule (the hydrogen and oxygen ends respectively) attract the negative chloride and positive sodium ions, pulling them away from each other. Again, whereas nonpolar and polar covalently bonded compounds break apart into molecules in solution, salts dissociate into ions. These ions are electrolytes; they are capable of conducting an electrical current in solution. This property is critical to the function of ions in transmitting nerve impulses and prompting muscle contraction. Q: What substances, which are distinct from acids and bases, form when ions form ionic bonds? A:

OPTIONS:
- oils
- vitamins
- water molecules
- salts

Answer the following question given this paragraph: Carbon cycles quickly between organisms and the atmosphere. Cellular respiration releases carbon into the atmosphere as carbon dioxide. Carbon is also released when organisms decompose. Human actions, such as the burning of fossil fuels, also release carbon into the atmosphere. Natural processes, such as volcanic eruptions, release carbon from magma into the atmosphere. Warm ocean waters also release carbon, whereas cold ocean water dissolves carbon from the atmosphere. Photosynthesis (autotrophs) removes carbon dioxide from the atmosphere and uses it to make organic compounds. Carbon cycles far more slowly through geological processes such as sedimentation. Runoff, rivers and streams dissolve carbon in rocks and carry it to the ocean. Sediments from dead organisms may form fossil fuels or carbon-containing rocks. Carbon may be stored in sedimentary rock for millions of years. Q: How long can carbon be stored in sedimentary rock? A:
****
A: millions of years

Problem:OPTIONS:
- uterus
- pectoral
- abdomen
- diaphragm

Answer the following question given this paragraph: Mammals breathe with the help of a diaphragm . This is the large muscle that extends across the bottom of the chest below the lungs. When the diaphragm contracts, it increases the volume of the chest. This decreases pressure on the lungs and allows air to flow in. When the diaphragm relaxes, it decreases the volume of the chest. This increases pressure on the lungs and forces air out. Q: What is the large muscle that extends across the bottom of the chest below the lungs called? A:
****
A:
diaphragm
