Answer:
0.1472 mol/L is the concentration of the barium hydroxide solution.
Explanation:
Mass of potassium hydrogen phthalate = 2.050 g
Molar mass of potassium hydrogen phthalate = 
According to reaction , 2 moles of potassium hydrogen phthalate reacts with 1 mole of barium hydroxide, then 0.01004 moles of potassium hydrogen phthalate will :
of barium hydroxide
Moles of barium hydroxide = 0.005020 mol
Volume of the barium hydroxide solution = 34.10 mL = 0.03410 L
1 mL = 0.001 L
Molarity of the barium hydroxiude silution :
0.1472 mol/L is the concentration of the barium hydroxide solution.
Pole
Explanation:
A magnetic pole is the point on a magnet where a magnet effect is strongest. Around a magnet, there are magnetic fields.
- The magnetic fields are force fields that leaves the north poles and enters through the south.
- The pole is where magnetic effects are the strongest.
- It is around the pole that the strongest magnetic effect on a magnet or magnetic material is felt.
- The strength of magnetic fields are strongest at the poles.

I think it will be D or B but my mine answer is D
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.
