The name of the compound NH4HSO4 is ammonium bisulfate.
Ammonium sulfate is the chemical name for NH4 2SO3.
These species are both polyatomic ions. NH4 + (ammonium ) and SO4 2- ( sulfate ) combine with opposite charges to form (NH4)2SO4 which is ammonium sulfate a polyatomic ionic bonding.
NH4HSO4 is acidic. When dissolved in water, it forms ammonium ion (NH4+) and hydrogen sulfate ion (HSO4-), which can donate a hydrogen ion (H+) to the solution, making it acidic.
0.758 moles of NH3 is the amount of moles in 50 grams of NH42SO4.
there is no charge. NH4 has a plus one charge and sulfate (SO4) has a minus two charge. since there is two NH4 the charges balance out
The solution with the lower freezing point would be the one with the higher van't Hoff factor. In this case, the van't Hoff factor for NH4 2SO4 is 3 (2 for NH4+ and 1 for SO4^2-), while the van't Hoff factor for Ce(NO3)4 is 5 (1 for Ce^4+ and 4 for NO3^-). Therefore, 0.012 M Ce(NO3)4 would have the lower freezing point.
To determine the number of moles in 50 grams of (NH4)2SO4, we first need to calculate the molar mass of the compound. The molar mass of (NH4)2SO4 is 132.14 g/mol. Next, we use the formula: moles = mass/molar mass. Therefore, moles = 50g / 132.14 g/mol ≈ 0.378 moles of (NH4)2SO4.
