Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.

Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

Calculate the ratio of H+ ions to OH– ions at a pH = 7. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide. Then divide the H+ concentration by the OH– concentration. Record this calculated ratio in Table A of your Student Guide.

Compare your approximated and calculated ratios of H+ ions to OH– ions at a pH = 7. Are they the same? Why or why not? Record your comparison in Table A.

What are some important functions cells perform in the human body?

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. A physical change doesn’t break the bonds between atoms of a substance or form new ones. Compounds can be broken down by a chemical change. A chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. What simple substance would a compound break into? The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?

A
separating water into different glasses

B
breaking frozen ice cubes with a hammer

C
running an electric current through water

D
boiling water to evaporate it on a stove
