Question

Rxn. 1: 7 g Zn Rxn. 2: 3.27 g Zn Rxn. 3: 1.31 g Zn

In the flask in which the balloon was inflated fully – assume here that the flask was filled with HCl to the top) – estimate the final volume of the balloon. You may assume that the pressure was equal to 1 Atm.

Answer 1

In(s) + 2HCl (aq) Znal, lag) + H₂Lg) gos that is The balloon enfiated due to the hydrogen Preoduced. moles of Hel used = o.lmol mass es zn used -7.0 gm moles of an . 7 gm 0 .104 more 7 u. moleculare mass of an is 65.4g 65.48/mol 2 moles of Hal needs 1 mole or an 1 moles or He needs o.h more of an And, on moles & Hel needs 0.05 mole di an. so at the end of the reeacon Hill gets completely used and reeactions stops leaving behind unreached an 30 As a moles of Ha Preoduces 1 mole of H₂ I mole of Hal " 0.5 more of H₂ And, on more of the Preoduces 0.05 mole of 142. So Assuming gos to be an deal one- Ideal gas equation - PV = n a T Temperaturee volume Gas constant Preessure no. dr. moles reoom temp. = 298 h. Temp. ts assumed to be Gas constant = 8.205745x10 m²- atm W-mol Preessooce assumed = 1 atm. I am av = 0.05 more & 8-2057 us x10 m atm x 298 Komor V = 1.2226 x 103 m3 As I m3 = 1000 Lires V = 1.2226 x 153 x 1000thes = 1.226 Ures.
