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 is the concentration of H+ ions at a pH = 7?

mol/L

What is the concentration of OH– ions at a pH = 7?

mol/L

What is the ratio of H+ ions to OH– ions at a pH = 7?

:1

1:1

Explanation:

What is the concentration of H+ ions at a pH = 7?

⇒ 0.0000001 mol/L  

What is the concentration of OH– ions at a pH = 7?

⇒ 0.0000001 mol/L  

What is the ratio of H+ ions to OH– ions at a pH = 7?  

1 :1

d. the weight of the book

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
