Answer:

Ba, N20, C 14H 10O 4

Explanation:

Ba: Calcium atoms in bones absorb x-rays, allowing doctors to clearly see the body's skeleton. X-rays can also be used to see blood vessels and internal organs. Special liquids, such as compounds made with the element barium (Ba), are swallowed by the patient, or injected into the bloodstream. The liquids help absorb x-rays, making certain tissues show up more clearly.

N20: Certain chemicals can be used as an anesthetic. Nitrous oxide (N2O) is commonly used in surgery and dentist offices.

C 14H 10O 4: Many acne medications contain benzoyl peroxide (C14H10O4), a compound that releases oxygen during a chemical reaction with skin. The oxygen kills anaerobic bacteria, which cannot live in the presence of oxygen.

0.415 g of an unknown triprotic acid are used to make a 100.00 mL solution. Then 25.00 mL of this solution is transferred to an
Arturiano [62]

Answer:

Explanation:

Initial burette reading = 1.81 mL

final burette reading = 39.7 mL

volume of NaOH used = 39.7 - 1.81 = 37.89 mL .  

37.89 mL of .1029 M NaOH is used to neutralise triprotic acid

No of moles contained by 37.89 mL of .1029 M NaOH

= .03789 x .1029 moles

= 3.89 x 10⁻³ moles

Since acid is triprotic ,  its equivalent weight = molecular weight / 3

No of moles of triprotic acid = 3.89 x 10⁻³ / 3

= 1.30   x 10⁻³ moles .
