input: OPTIONS:
- brg and brf
- brf2 and brf4
- brf and brf4
- brf and br2 Now, answer this question: Answer the following question given this paragraph: redox reaction will occur. The only question is whether lead will be oxidized to Pb(II) or Pb(IV). Because BrF3 is a powerful oxidant and fluorine is able to stabilize high oxidation states of other elements, it is likely that PbF4 will be the product. The two possible reduction products for BrF3 are BrF and Br2. The actual product will likely depend on the ratio of the reactants used. With excess BrF3, we expect the more oxidized product (BrF). With lower ratios of oxidant to lead, we would probably obtain Br2 as the product. Exercise Predict the products of each reaction and write a balanced chemical equation for each reaction. Q: What are the two possible reduction products for brf3? A:
A:
output: brf and br2

Answer the following question given this paragraph: All living thingseven the simplest life formshave a complex chemistry. Living things consist of large, complex molecules, and they also undergo many complicated chemical changes to stay alive. Thousands (or more) of these chemical reactions occur in each cell at any given moment. Metabolism is the accumulated total of all the biochemical reactions occurring in a cell or organism. Complex chemistry is needed to carry out all the functions of life. Q: What is the accumulated total of all the biochemical reactions occurring in a cell or organism called? A:

OPTIONS:
- respiration
- expansion
- circulation
- metabolism

Answer: metabolism

Problem: OPTIONS:
- hormones
- chlorophyll
- air
- water
Q: Answer the following question given this paragraph: The simple sugars form the foundation of more complex carbohydrates. The cyclic forms of two sugars can be linked together by means of a condensation reaction. The figure below shows how a glucose molecule and a fructose molecule combine to form a sucrose molecule. A hydrogen atom from one molecule and a hydroxyl group from the other molecule are eliminated as water, with a resulting covalent bond linking the two sugars together at that point. Q: During the condensation reaction of sugars what is removed, linking the two sugars? A:
Answer: water

Problem:OPTIONS:
- the head
- the thorax
- the chest cavity
- the abdomen

Answer the following question given this paragraph: An insect's abdomen contains most of the internal organs. Like other arthropods, insects have a complete digestive system. They also have an open circulatory system and central nervous system. Like other terrestrial arthropods, they have trachea for breathing air and Malphigian tubules for excretion. Q: Where are more of an insect's internal organs kept? A:
****
A: the abdomen

- pistil
- stamen
- genome
- chloroplast
chloroplast
