Question 2: Based on the reaction shown here. Assuming the reaction takes place with excess Aluminum bromide (AIBr3), how many grams of Potassium
bromide (KBr) could be produced from 14.93 grams of Potassium sulfatel
(K2504)? *
2 AlBr3 + 3 K2SO4 → 6 KBr + 1 Al2(SO4)3

- decrease the number of plants and animals living in the water.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
