10 moles of HCl is added to excess of magnesium and forms 4 miles of hydrogen gas percentage yield is?

Answer» G reactantsA REACTION finishes when ONE of the reactants is all used up. The other reactant has nothing left to react with, so some of it is left over:the reactant that is all used up is called the limiting reactantthe reactant that is left over is DESCRIBED as being in excessThe mass of PRODUCT formed in a reaction depends upon the mass of the limiting reactant. This is because no more product can form when the limiting reactant is all used up

What is Water of Crystallization? Support it with the help of equations? Lookin' for a detailed answer :).

Answer»

Water of crystallization is defined as water that comes from a crystal substance after heat is applied. An example of water of crystallization is the water that drips off of a water crystal hanging from the eaves of the house as it warms up after a FREEZING rain.In chemistry, water(s) of crystallization or water(s) of hydration are water MOLECULES that are present inside [crystal]s. Water is often incorporated in the formation of crystals from aqueous solutions.[1] In some contexts, water of crystallization is the total MASS of water in a substance at a given temperature and is mostly present in a definite (stoichiometric) ratio. Classically, "water of crystallization" refers to water that is FOUND in the crystalline framework of a METAL complex or a salt, which is not directly bonded to the metal cation.Upon crystallization from water or moist solvents, many compounds incorporate water molecules in their crystalline frameworks. Water of crystallization can generally be removed by heating a sample but the crystalline properties are often lost. For example, in the case of sodium chloride, the dihydrate is unstable at room temperature.Coordination sphere of Na+ in the metastable dihydrate of sodium chloride (red = oxygen, violet = Na+, green = Cl−, H atoms omitted).[2]Compared to inorganic salts, proteins crystallize with large amounts of water in the crystal lattice. A water content of 50% is not uncommon for proteins.Explanation:Hope it helps you
