One element, two atoms.
Element is Hydrogen.
Two atoms of Hydrogen.
Hello!
1) What is the limiting reactant?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂OThe
Limiting Reactant is the one that is in the lowest amount in the reaction and determines how many moles are produced. You can see that in this chemical equation there is only one reactant since this reaction is a
decomposition reaction. So,
the limiting reactant is Al(OH)₃.2) How many grams of water are produced?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂O
So, we are going to use the following conversion factor to go from grams of Al(OH)₃ to grams of water:
So,
6,17 grams of Water are produced.
Have a nice day!
Answer:
The Relative Formula Mass of Fe(NO₃)₂ is 179.8524 grams
Explanation:
The Relative Formula Mass is the mass of one mole of a compound expressed in grams, obtained by adding together the Relative Atomic Masses, RAM, of the elements which makes the compound
The Relative Formula Mass of a compound is the same as its Relative Molecular Mass
The relative formula mass of Fe(NO₃)₂ is given as follows;
The relative atomic mass of Fe = 55.845 amu
The relative atomic mass of nitrogen, N = 14.0067 amu
The relative atomic mass of oxygen, O = 15.999 amu
Therefore, we have;
The formula mass of Fe(NO₃)₂ = (55.845 + 2×(14.0067 + 3×15.999)) amu = 179.8524 amu
The Relative Formula Mass of Fe(NO₃)₂ = 179.8524 grams.
