Answer:
0.363g citric acid
Explanation:
Sodium hydroxide (NaOH) reacts with acids, thus:
NaOH + H⁺ → H₂O + Na⁺
The volume of titration is:
18.39mL - 0.73mL = 17.66mL
Moles of this volume in 0.107M NaOH are:
0.01766L × (0.107 mol / L) = 0.00189mol NaOH ≡ mol citric acid<em> -Assuming the only acid in pear juice is citric acid-</em>
As molar mass of citric acid is 192.124g/mol:, Mass of citric acid is:
0.00189mol citric acid × (192.124g / mol) = <em>0.363g citric acid</em>
I hope it helps!

Answer:
HCl
Explanation:
Phosgene (COCl₂) on reaction with moisture in lungs converts into Carbon dioxide and hydrochloric acid.
COCl₂ + 2 H₂O → CO₂ + 2 HCl
The HCl produced in lungs causes problems. It reacts with alveoli proteins resulting in suffocation, coughing, eyes and throat irritation and difficulty in breathing.
