D is the answer cause two h20 + o2(g)
HCN is a weak acid, with A Ka = 4.0 x 10-10.
Hello!
The formula is density = mass / volume
=> volume = mass / density
volume = ?
mass = 2500.0 g
density = 10.5 g/cm3
volume = mass / density
volume = 2500.0 g / 10.5 g/cm3
volume = 2380.95 cm3
Hope this help!
You have already gotten the balanced equation. And the ratio of mol number of reactants and production is the ratio of coefficient. So there is 6.4/8*11=8.8 mol oxygen needed. The mass is 8.8*32=281.6 g.
