How many water molecules are presented in the hydrate magnesium sulfate heptahydrate?
In magnesium sulfate heptahydrate, the term "heptahydrate" means there are seven water molecules associated with each formula unit of magnesium sulfate. So, in one formula unit of magnesium sulfate heptahydrate, there are 7 water molecules.
What does Magnesium chloride and water form?
When magnesium chloride is dissolved in water, it forms a clear liquid solution. This solution contains magnesium ions (Mg2+) and chloride ions (Cl-), which are the products of the dissociation of magnesium chloride in water.
Is magnesium sulfate in water a physical or chemical change?
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
How Anhydrous magnesium sulphate acting like drying agent?
a drying agent works by removing water molecules that may be contaminating a chemical product. Magnesium Sulfate (MgSO4) is an ionic salt. The charged Mg2+ and SO42- ions have a high affinity for water molecules and therefore are able to remove them from the product thus "drying it" of water. In this sense "drying" means "removing water" rather than "making less wet"
What dose 6H2O mean?
6H2O refers to 6 molecules of water. The "6" indicates the number of water molecules present in the chemical compound.

How many molecules of water are present in 1g of water?
The answer is 0,166.10e23 molecules.
What does Magnesium chloride and water form?
When magnesium chloride is dissolved in water, it forms a clear liquid solution. This solution contains magnesium ions (Mg2+) and chloride ions (Cl-), which are the products of the dissociation of magnesium chloride in water.
Write the reactions of hard water with soap which leads to the formation of white insoluble scum?
When hard water reacts with soap, it forms an insoluble scum due to the reaction between the calcium and magnesium ions present in the water with the soap. The calcium and magnesium ions react with the soap molecules to form calcium and magnesium salts of the fatty acids, which are insoluble and appear as white scum in the water.
Can magnesium float on water?
Metals have a high density and they feel heavy so as magnesium is a metal it will not float in water due to the tight compression on the molecules packed in it.
What would you get if you mixed magnesium and dilute acid together?
a magnesium salt of the acid, and hydrogen gas - water is already present.
Is magnesium sulfate in water a physical or chemical change?
When magnesium sulfate dissolves in water, it undergoes a physical change, not a chemical change. The molecules of magnesium sulfate are simply dispersed in the water, but no new chemical substances are formed.
Magnesium oxide reacting with water?
Magnesium hydroxide Oxides are in general Bronsted bases, and very strong ones at that. Bronsted bases like to pick up hydrogens, and so in the presence of water O2- will pick up a hydrogen from water: O2- + H2O ---> 2 OH- In this particular case since magnesium hydroxide is an insoluble compound you get: MgO + H2O ---> Mg(OH)2
The differences in the reactions of potassium magnesium and copper with water?
Potassium reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. Magnesium reacts slowly with water, liberating hydrogen gas and forming magnesium hydroxide. Copper does not react with water at room temperature due to its low reactivity with water molecules.
What does 6h2o stand for?
6H2O represents 6 molecules of water. The "6" indicates the number of water molecules present.
What is the name of the compound MgBr2 6H2O?
magnesium bromide hexahydrate
