Answer the following question given this paragraph: Ocean water normally dissolves some of the carbon dioxide in the atmosphere. The burning of fossil fuels has increased the amount of carbon dioxide in the atmosphere. As a result, ocean water is also dissolving more carbon dioxide. When carbon dioxide dissolves in water, it forms a weak acid. With higher levels of dissolved carbon dioxide in ocean water, the water becomes more acidic. This process is called ocean acidification. Q: What has the burning of fossil fuels increased in the atmosphere? A:
****
A: carbon dioxide

Answer the following question given this paragraph: Because the nuclei of each H atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). But because the two atoms involved in the covalent bond are both H atoms, each nucleus attracts the electrons by the same amount. Thus the electron pair is equally shared by the two atoms. The equal sharing of electrons in a covalent bond is called a nonpolar covalent bond. Now consider the HF molecule:. Q: Because the nuclei of each h atom contain protons, the electrons in the bond are attracted to the nuclei (opposite charges attract). but because the two atoms involved in the covalent bond are both h atoms, each nucleus attracts the electrons by the same amount. thus the electron pair is equally shared by these? A:
OPTIONS:
- four atoms
- one atom
- nine atoms
- two atoms
two atoms
