Answer:

601mmhg

Explanation:

Pgas = Patm - hρg

Height of water = 14.4cm

Convert to mm

1 cm = 10mm

14.4 cm =

= 14.4cm × 10mm

= 144mm

hpg = 144 mmhg

Ptotal = Patm - hog

= 745mmhg - 144 mmhg

= 601mmhg

The total pressure of gases inside the graduated cylinder = 601mmhg

A sample of a chromium-containing alloy weighing 3.450 g was dissolved in acid, and all the chromium in the sample was oxidized
Zina [86]

Answer:

H_2O + 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-

Explanation:

Reduction half reaction

2H_2O + CrO_4^2- + 3e -> CrO_2^- + 4OH^-

Oxidation half reaction

2OH^- + SO_3^2- -> SO_4^2- + H_2O + 2e

Balanced overall equation

H_2O + 2CrO_4^2- + 3SO_3^2- -> 3SO_3^2- + 2CrO_2^- + 2OH^-
