Q: Group 16 is called what? Read this paragraph and choose the correct option from the provided answers: Group 16 is called the oxygen group. The first three elements in this group are nonmetals. They are followed by one metalloid and one metal. All the elements in the oxygen group have six valence electrons, and all are reactive. Oxygen (O), for example, readily reacts with metals to form compounds such as rust. Oxygen is a gas at room temperature. The other four elements in group 16 are solids. Choices: - noble gases - the acid group - metalloids - the oxygen group A:
the oxygen group

Q: The fast motion of gas particles gives them a relatively large amount of what energy? Read this paragraph and choose the correct option from the provided answers: Gas particles are in constant rapid motion in random directions . The fast motion of gas particles gives them a relatively large amount of kinetic energy. Recall that kinetic energy is the energy that an object possesses because of its motion. The particles of a gas move in straight-line motion until they collide with another particle or with one of the walls of its container. Choices: - residual energy - Potential energy - Chemical energy - kinetic energy A:
kinetic energy
