he analytical concentration of lactic acid in blood is generally less than 1.20 x 10-4 M, corresponding to the sum of [lactate] and [lactic acid]. During strenuous exercise, however, oxygen in the muscle tissue is depleted, and overproduction of lactic acid occurs. This leads to a condition known as lactic acidosis, which is characterized by elevated blood lactic acid levels (approximately 5.00 x 10-3 M). The pKa of lactic acid is 3.9. a) What is the actual lactic acid concentration under normal physiological conditions? b) what is the actual lactic acid concentration during lactic acid acidosis?

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the answer would be a

1 is the answer to this problem
