Answer:
D
Explanation:
Breaking bonds absorbs (Requires) energy. Forming bonds releases it. It's kinda backwards but that's how it works. :)
Ba(OH)2 dissociate according to the following equation
Ba(OH)2----> Ba 2+ + 2OH-
Moles of Ba(OH)2 = 4.02 /171(molar mass of Ba(OH)2 )= 0.0235 moles
by use of mole ratio of Ba(OH)2 to OH- which is 1:2 the moles of OH = 0.0235 x 2=0.047 moles in one liter = 0.047/1000= 4.7 x10^-5
POh=- log (OH-)
that is -log (4.7 x10^-5) = 4.34
Ph= 14 - POH
PH is therefore = 14 - 4.34 = 9.66
The answer would be "This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allowed pain to travel within the body" because this statement best explains how acupuncture reduces pain.
To support such answer, it must be noted that acupuncture is a traditional Chinese mode of pain-relieving through the insertion of extremely fine needles into the skin at specific points in the body known as "acupoints". This may relieve pain by releasing the hormone known as endorphins (happy hormone), which is the body's natural pain-killers and by affecting the brain part that governs serotonin- brain chemical which involved mood.
Answer:
Ovary
Explanation:
ovaries produce the most estrogen in females.
It is 2.5g/ml. You can find this answer by taking the mass (25g) and dividing it by the volume (10ml) and you will get your answer of 2.5g/ml.
