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.
When 100 ml of M/10 H2SO4 is mixed with 500 ml of My/10 NaOH then nature of resulting solution and normality of excess reactant left is

Q. How to calculate atomic mass of an element? Copper survive as a mixture of two isotopes. The lighter isotope (Cu-63) amid 29 protons and 34 neutrons makes up 69.17% of coppe
Q. Explain about Coordination Isomerism? Coordination Isomerism: If the complex is a salt having both cation and anion as complex ions then the ligands can exchange position
Q. Briefly explain about Alloys? Ans. Pure metals are malleable. Metals that are harder, stronger and less malleable are sometimes required. These characteristics may be a
