An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.
The mas %(m/m) concentration of the solution is calculated using the below formula
mass of the solute/mass of the solvent x100
mass of the solute = 500g
mass of the solvent = 2.50kg in grams= 2.50 x1000 = 2500 g
%(M/M)= 500 g/2500g x100= 20% (m/M)
Number 36 would be Krypton.
Answer:
4H2O(g)+3Fe(s)⟶Fe3O4(s)+4H2(g)
4H2O(g)+3Fe(s)⟶Fe3O4(s)+4H2(g)
