Elements form compounds in an attempt to
-
Become more stable
-
Disperse energy
-
Become inert
-
Gain energy
Correct Answer
A. Become more stableExplanation
Elements form compounds in an attempt to become more stable. This is because elements have a tendency to fill their outermost electron shell, which is the most stable configuration. By forming compounds, elements can share, donate, or accept electrons to achieve a full outer shell, thereby increasing their stability. This process allows them to attain a lower energy state and reduces their reactivity, making them less likely to undergo chemical reactions.Rate this question:

Boyle’s law states that a gas volume is inversely proportional to its pressure, at a constanttemperature. Which of the following statements best describes this relationship?
-
As pressure increases, volume decreases
-
As pressure increases, volume increases
-
As pressure increases, volume remains constant
-
As pressure decreases, volume remains constant
Correct Answer
A. As pressure increases, volume decreasesExplanation
Boyle's law states that as the pressure exerted on a gas increases, its volume decreases, assuming that the temperature remains constant. This means that there is an inverse relationship between pressure and volume. When pressure is increased, the gas molecules are forced closer together, resulting in a decrease in volume. Conversely, when pressure is decreased, the gas molecules have more space to move and the volume increases. Therefore, the statement "As pressure increases, volume decreases" accurately describes this relationship.Rate this question:

Unsaturated aliphatic hydrocarbons, unlike saturated compounds, have double or triple bonds between carbon atoms. These double or triple bonds provide sites for chemical reactions to occur, making unsaturated hydrocarbons more chemically reactive. In contrast, saturated compounds have only single bonds, which are relatively stable and less likely to undergo chemical reactions. Therefore, unsaturated aliphatic hydrocarbons are more chemically reactive compared to saturated compounds.Rate this question:
