Taking rust to be Fe2O3, you would have the following reaction:Fe2O3 + 6HCl ==> 2FeCl3 + 3H2O
100 g Fe2O3 x 1 mole Fe2O3/159.7 g = 0.626 moles Fe2O3
moles HCl needed = 0.626 moles Fe2O3 x 6 moles HCl/mole Fe2O3 = 3.76 moles HCl needed
Mass HCl needed = 3.76 moles HCl x 36.5 g/mole = 137 g HCl needed
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
The molar mass of potassium chloride is 74,5513.
The hydrogen molecule, H2, contains two hydrogen atoms and thus, has twice the mass of a single hydrogen atom.
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
Molar mass of ammonia is 17.031 whereas molar mass of hydrogen chloride (or hydrochloric acid) is 36.461. Hence if given masses, there is 1 mole ammonia and 2 moles HCl. Hence there is more number of hydrogen chloride.
yes
One atom of hydrogen reacts with one atom of chlorine forming one molecule of hydrogen chloride (hydrochloric acid). An atom of hydrogen has less mass than one of chlorine so 1 gram of hydrogen contains more hydrogen atoms than one gram of chlorine.
The mass of the oxygen and hydrogen that react to form water will be exactly equal to the mass of the water produced.
The mass of silver nitrate is 30,6 g.
The percentage of sodium in sodium chloride is 39,665 83 %. Mass of NaCl = Mass of sodium X 2,51
1,26 moles hydrogen chloride (not hydrochloric acid) is 45,94 g.
Calcium Chloride is a complete salt.There are no replaceble H+ or OH-.So it does not react with NaHCO3.So there is no change of mass.
14.35 g + 8.5 g - 5.85 g or 17 g.
The molar mass of potassium chloride is 74,5513.
The molar mass of sodium chloride is 58,44.
The Atomic Mass of hydrogen is 1.008 and that for chlorine is 35.45. The moles of hydrogen available are therefore 0.490/1.008 = 0.486 and the moles of chlorine available, 50/35.45, are greater than 1. Each molecule of hydrogen chloride requires one atom each of chlorine and hydrogen. Therefore, with the specified conditions, hydrogen is stoichiometrically limiting, and 0.486 moles of HCl can be made.
