Preparation of Ammonium Sulfate (NH4)2SO4
Ammonium sulfate occurs naturally from the mineral mascagnite in volcanic fumaroles & due to coal fires on some dumps.Ammonium sulfate is formed by adding finely divided gypsum to an ammonium carbonate solution.(NH4)2CO3 + Ca
SO4 → (NH4)2SO4 + Ca
CO3
2 NH3 + H2SO4 → (NH4)2SO4
Chemical Properties of Ammonium Sulfate (NH4)2SO4
Ammonium sulfate decomposes upon heating above 250 °C, forming ammonium bisulfate. Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, và water.Xem thêm: Đề thi lớp 5 cuối kì 2 môn tiếng việt lớp 5 năm 2022, đề thi học kì 2 môn tiếng việt 5 có lời giải

Computing molar mass (molar weight)
To calculate molar mass of a chemical compound enter its formula & click "Compute". In chemical formula you may use:Any chemical element. Capitalize the first letter in chemical symbol và use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, t
Bu, Bzl, Bn, Dmgparantesis () or brackets <>.Common compound names.Examples of molar mass computations: Na
Cl, Ca(OH)2, K4
SO4*5H2O,water,nitric acid,potassium permanganate,ethanol,fructose.Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions & allows lớn convert from weight to number of moles & vice versa.
Computing molecular weight (molecular mass)
To calculate molecular weight of a chemical compound enter it"s formula, specify its isotope mass number after each element in square brackets.Examples of molecular weight computations: C<14>O<16>2, S<34>O<16>2.Definitions of molecular mass, molecular weight, molar mass & molar weight
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to lớn 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance & is expressed in g/mol.Weights of atoms and isotopes are from NIST article.Related: Molecular weights of amino acids
