Calculate the ratio of h+ ions to oh-ions at a ph = 6.
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 = 6. are they the same? why or
why not? record your explanation in table a.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?
