Answer the following question given this paragraph: A hydrocarbon is an organic compound that is made up of only carbon and hydrogen. A hydrocarbon is the simplest kind of organic molecule and is the basis for all other more complex organic compounds. Hydrocarbons can be divided into two broad categories. Aliphatic hydrocarbons are hydrocarbons that do not contain the benzene group or a benzene ring . Aromatic hydrocarbons contain one or more benzene rings. In this concept, we will discuss the aliphatic hydrocarbons. Q: What is an organic compound that is made up of only carbon and hydrogen? A:
OPTIONS:
- an acid
- a catalyst
- a component
- a hydrocarbon
a hydrocarbon

Answer the following question given this paragraph: Electric current is a continuous flow of electric charge. It is measured in amperes (A). Direct current (DC) flows in just one direction. Alternating current (AC) keeps reversing direction. Q: What is a continuous flow of electric charge called? A:
OPTIONS:
- powered current
- microwave current
- magnetism
- electric current

Answer: electric current

Question: Answer the following question given this paragraph: To balance a nuclear reaction. The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. The resulting daughter nuclei have a lower mass and are lower in energy (more stable) than the parent nucleus that decayed. In contrast, in anuclear transmutation reaction, a nucleus reacts with a subatomic particle or another nucleus to form a product nucleus that is more massive than the. Q: When an unstable nucleus emits radiation and is transformed into the nucleus of other elements this is called? A:
OPTIONS:
- naturally decay
- explosive decay
- fusion decay
- radioactive decay
Answer: radioactive decay
