Rashid [163]
<span>Answer: Nothing is balanced in your final equation: not H, not O, not Cr, not I and your charges aren't either. Start with your 2 half reactions: I- --> IO3- Cr2O72- --> 2 Cr3+ Balance O by adding H2O: I- + 3 H2O --> IO3- Cr2O72- --> 2 Cr3+ + 7H2O Balance H by adding H+: I- + 3 H2O --> IO3- + 6 H+ Cr2O72- + 14 H+ --> 2 Cr3+ + 7H2O Balance charge by adding e-: I- + 3 H2O --> IO3- + 6 H+ + 6 e- Cr2O72- + 14 H+ + 6 e- --> 2 Cr3+ + 7H2O Since the numbers of electrons in your two half reactions are the same, just add them and simplify to give: Cr2O72- + I- + 8 H+ --> IO3- + 2 Cr3+ + 4 H2O</span>

In the experiment the hydrogen gas is collected in a eudiometer tube over water. If the barometric pressure and the temperature
aleksandrvk [35]

Answer:

732.9 mmHg

Explanation:

At the eudiometer tube is the mixture of water and hydrogen gas (H₂), by Dalton's law of the partial pressure, the total pressure of a gas mixture (barometric pressure) is equal to the sum of the partial pressures of the components of the mixture:

Ptotal = Pwater + Phydrogen

752.3 = 19.4 + Phydrogen

Phydrogen = 752.3 - 19.4

Phydrogen = 732.9 mmHg
