Lack of temperature and lack of moisture
% by mass = (mass solute/mass solution)*100%
mass of the solute = 54.7 g
mass of the solution = mass solute + mass solvent=54.7+500=554.7 g
% by mass = (54.7/554.7)*100%≈0.0986*100% = 9.86%
1) No. of atoms of all elements participating in the reaction are to be balanced.
2) Pressure Change should be noted (because, if ∆P≈0, it shows the reaction is in equilibrium).
3) The theoretical representation of the reaction should be balanced well.
On a topographic map, the contour lines follow a certain elevation across the terrain. So here's what each of the things you mention would mean: If the lines are far apart, that means that there is little or no slope in that area of the map
