Q. Use of Reactants in Excess?
Ans.
Consider a recipe for pancakes that calls for 2 cups of pancake batter mix and 1 cup of water. The result of this recipe is 14 pancakes.
Let's say you have only one cup of pancake mix. Can you still make the recipe? Of course! just make half the recipe. In this case the pancake mix is the limiting reagent.
What if you have 4 cups of water but only 2 cups of pancake mix? The two reactants aren't present in the correct ratio, so one of these is the limiting reagent. It seems that the limiting reagent is the pancake mix and that there are 2 cups of water in excess. A reactant in excess will always have an amount left over after the other reactant is used up.
Now in chemical terms, let's examine the idea of limiting reagent and excess.
2 Mg + O2 -> 2 MgO
Let's say in our case 1 mole of oxygen reacts with 3 moles of magnesium. You still obtain 2 moles of magnesium oxide. There is 1 mole of magnesium in excess, which tells you oxygen is the limiting reagent.
A polymer instance has chain of different type of lengths and hence its molecular mass is all the time expressed as an average on the other hand natural polymer like proteins consi

how to find stability of carbocations in benzene ring..??? and how how to find optically inactive isomers ??? (say of--C2H5Cl) how to find the weakest C-X (carbon-halogen bond in
Explain The compound decarboxylates The compound decarboxylates; it is a disubstituted malonic acid in which the two a substituents are connected within a ring. The net effect
Calculate the ideal rM/rX ratio for cation-anion and anion-anion contacts of an octahedral arrangement of anions around a cation as show in one plane in the figure below.
Uncertainty principle gave the concept of: (1) Probability (2) An orbital (3)Physical meaning of Ψ the Ψ (4)All the above Ans: Probability
the order of stability of carbocations and carbanions For carbocation 3 degree > 2 degree > 1 degree for carbanion 1 degree > 2 degree > 3 degree
We are asked to design a qualitative analysis scheme that can be used to determine which cations are present in a solution containing only four of the following cations: Pb2+, Ag+,
