Question: Answer the following question given this paragraph: Covalent bonds form because they give atoms a more stable arrangement of electrons. Look at the hydrogen atoms in Figure above . Alone, each hydrogen atom has just one electron. By sharing electrons with another hydrogen atom, it has two electrons: its own and the one in the other hydrogen atom. The shared electrons are attracted to both hydrogen nuclei. This force of attraction holds the two atoms together as a molecule of hydrogen. Q: What bonds form because they give atoms a more stable arrangement of electrons? Choices: - Hydrogen bond - Ionic bond - Polar bond - covalent A:
Answer: covalent

Question: Answer the following question given this paragraph: Air temperature in the stratosphere layer increases with altitude. Why? The stratosphere gets most of its heat from the Sun. Therefore, it's warmer closer to the Sun. The air at the bottom of the stratosphere is cold. The cold air is dense, so it doesn't rise. As a result, there is little mixing of air in this layer. Q: Where does the stratosphere get most of its heat? Choices: - time - earth - volcanoes - sun A:
