Answer the following question given this paragraph: A: Electric charges flow when they have electric potential energy. Potential energy is stored energy that an object has due to its position or shape. Q: What is the term for stored energy that an object has due to its position or shape? Choices: - kinetic energy - mechanical energy - vertical energy - potential energy A:
potential energy

Answer the following question given this paragraph: Pure elements with a high metallic character, meaning those that have chemical properties most similar to properties of metals, are generally very reactive. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. Within a compound, metal atoms have a relatively low attraction to shared electrons, as indicated by their low electronegativity values. By following the trend summary in Figure below , you can see that the most reactive metals would reside in the lower left portion of the periodic table. The most reactive metal that occurs naturally in reasonable quantities is cesium, which is always found in nature as a compound, never as a free element. It reacts explosively with water and will ignite spontaneously in air. Francium is below cesium in the alkali metal group, but it is so rare that many of its properties have never even been observed. Q: Exemplified by cesium, which ignites spontaneously in air, pure elements with a high metallic character tend to be very what? Choices: - radiactive - inactive - proactive - reactive A:
reactive

Answer the following question given this paragraph: Saturated hydrocarbons contain only single bonds between carbon atoms. They are the simplest hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in Figure below . Each carbon atom is bonded to three hydrogen atoms in this compound, which is named ethane. Q: What are the simplest hydrocarbons? Choices: - unsaturated hydrocarbons - complex carbohydrates - fossil fuels - saturated hydrocarbons A:
saturated hydrocarbons

Answer the following question given this paragraph: Q: Overharvesting is especially challenging for species with what type of habitat? Choices: - tundra - allowed - classified - restricted A:
restricted
