Calculate the molecular mass of H2SO4.

We know that Hydrogen H has +1 charge and Oxygen O has -2 charge. Since H2SO4 molecule is neutral so the charges will be balanced by Sulfur S Now balancing the equation gives 2...

When reactive metals react with dilute hydrochloric acids, gives a salt and hydrogen gas Metal + Dilute acid → Salt + Hydrogen Reaction between Iron and H2SO4: Fe + H2SO4 → FeSO4 +...

Solution: weight of metal carbonate/GEW = NaXVa in lt 0.84/GEW = 0.5X40/1000 GEW of metal carbonate = 42 GEW of Metal = 42 - GEW of CO3-2 = 42-30 = 12g

The table below lists the conjugate bases for the given Bronsted acids.  Bronsted acid Conjugate base HF                   F- H2SO4            HSO4 HCO3- ...

Oxidation Number of sulphur is +6

H2SO4       +6  H2SO3       +4  H2S2O8     +6  H2S2O7     +6

Answer 1:  The molecular mass of a substance is the sum of the atomic masses of all the atoms present in a molecule of that substance. It is expressed in atomic mass...

(a) 1 mole of iron (Fe) = 56 g (molar mass)  Since 56 g of iron = 1 mol  Therefore, 112 g of iron= 1/ 56 ×112 mol = 2 mol  (b) Molar...

(a) KOH  (39 +16+1) = 56 g mol–1  (b) NaHCO3  23 + 1 + 12 + (3 × 16) = 84 g mol–1  (c) CaCO3  40 + 12 + (3 × 16) = 100 g...

Because it forms a dense fog of sulphuric acid which does not condense easily.
