Explanation:
solve fsolve for x in terms of r.
rx + 24 = -9or x in tsolve for x in terms of r.
rx + 24 = -9erms of r.
solve for x in terms of r.
rx + 24 = -9
rx + 24 = -9
According to the reaction equation:
Ba(OH)2 ↔ Ba2+ + 2OH-
when 0.015 M 0.015M 2*0.015M
∴ [OH-] = 0.03 m
so we can get the POH = - ㏒ [OH-]
by substitution:
∴ POH = -㏒ 0.03
= 1.52
and then we can get the PH from this formula:
PH + POH = 14
so by substitution:
∴PH = 14 - 1.52
≈ 12.48
Answer:
H₂ + O₂ → H₂O
Now, check that oxygen has two atoms on the left and one on the right
so, you put 2 on the right side
H₂ + O₂ → 2H₂O
oxygen is balanced so, add 2 on H₂ to balance out hydrogen
THE FINAL BALANCED EQUATION:
<h2>
2H₂ + O₂ → 2H₂O</h2>
Answer:
Regurgitation happens when a mixture of gastric juices, and sometimes undigested food, rises back up the esophagus and into the mouth. In adults, involuntary regurgitation is a common symptom of acid reflux and GERD. It may also be a symptom of a rare condition called rumination disorder. Hope it helps.
