Compound formula for Mg and S?
Magnesium sulfide has the molecular formula of MgS. It is wholly comprised of the elements magnesium (Mg) and sulfur (S).
What is the formula for the compounds formed by Fe2 Cl?
The net ionic charge on the compound is zero. So if you have two chloride ions (Fe+ Cl- Cl-) the charges will cancel. Thus the formula is FeCl2.
What is the charge for silver chloride?
The overall charge for any compound is balanced. The charge for Ag is +1, and the charge for chloride is -1. They cancel each other out.
What is the difference between magnesium sulfate and magnesium chloride.what is the use of these salts in agriculture soil?
Well the main difference between the two is that they are totally different compounds. Magnesium sulfate has derivatives of sulfur and oxygen when magnesisum chloride is a derivitive of chlorine. Magnesium sulfate has a polyatomic ion (sulfate); magnesium chloride is made of a cation and an anion. In the magnesium sulfate, the magnesium and the sulfate ion cancel the charges so the both have a charge of 0. In magnesium chloride, the magnesium cation has a charge of 0 while the chloride anion has a charge of 2-.As for the uses of salts in agriculture, MgSO4 is often encountered as the heptahydrate epsomite (MgSO4·7H2O), commonly called Epsom salt. In agriculture and gardening, magnesium sulfate is used to correct magnesium deficiency in soil, since magnesium is an essential element in the chorophyll molecule. It is most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, peppers and cannabis. The advantage of magnesium sulfate over other magnesium soil amendments (such as dolomitic lime) is its high solubility.As for the magnesium chloride, its uses include using for dust and erosion control and for experimenting anti lipid effects in animals.
Why do ionic compounds have an overall neutral electric charge?
Ions can be single atoms, as the sodium and chloride in common table salt sodium chloride, or more complex groups such as the carbonate in calcium carbonate. But to be considered an ion, they must carry a positive or negative charge. Thus, in an ionic bond, one 'bonder' must have a positive charge and the other a negative one. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Positive to positive and negative to negative ionic bonds do not occur.
What is the formula for an ionic compound that contains the elements magnesium and chlorine?
Magnesium ions have a 2+ charge, while chloride ions each have 1- charge. In order to cancel out the charges to create a stable, neutral compound, the formula must be MgCl2.
How many chloride ions are needed to cancel the 2 charge of magnesium in magnesium chloride (MgC12)?
Two.
Compound formula for Mg and S?
Magnesium sulfide has the molecular formula of MgS. It is wholly comprised of the elements magnesium (Mg) and sulfur (S).
What is the formula for the compounds formed by Fe2 Cl?
The net ionic charge on the compound is zero. So if you have two chloride ions (Fe+ Cl- Cl-) the charges will cancel. Thus the formula is FeCl2.
What is the formula for ionic compound formed between magnesium and fluorine?
These are the ions and their charges: Mg+2 F-1The charges have to add up to zero, so two -1 fluorine cancel out one +2 magnesium ion: Mg+2 F-1 F-1Simplify: MgF2
What is the charge for silver chloride?
The overall charge for any compound is balanced. The charge for Ag is +1, and the charge for chloride is -1. They cancel each other out.
What is the combination of symbols that shows the ratio of elements in a compound?
The ratio is called the chemical formula. Naming these compounds is called nomencalture. Example: NaCl sodium (Na) has a +1 charge and chlorine (Cl) has a -1 charge the charges cancel out and therefore the ratio is one to one Another Example: MgCl2 magnesium (Mg) has a charge of +2 and chlorine (Cl) has a charge of -1. It takes two chlorines to cancel out one magnesium so the ratio is one to two.
Magnesium reacts with HCl to form hydrogen and magnesium chloride Write the balanced net ionic equation for this reaction?
Magnesium is in group 2 so its valency is +2Oxygen is in group 6 so its valency is -2The numbers are the same, so there is no need to cross them over, and they both cancel down to 1, so the formula for Magnesium Oxide is MgOOxygen molecules are diatomic, so the formula for Oxygen is O2Magnesium's chemical formula is MgUsing these, the equation starts out as:Mg + O2 => MgOBalancing this gives2Mg + O2 => 2MgO

How many chloride ions are in sample of salt that contains 2 moles of MgCl2?
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2
Why is the formula for milk of magnesia written MgOH2 instead of MgO2H2?
I think what you mean is Mg(OH)2 vs MgO2H2. This is an ionic compound because it has a metal (magnesium). In it, Mg+2 is the cation (positive ion) and OH- is the anion. Because an ionic compound must have a zero net charge, there needs to be two OH- ions to cancel the +2 charge of the magnesium. so in the first formula it is shown that there are two OH- ions, but the second one is incorrect because OH is one ion and the elements are not separately written like that in an ionic compounds formula. hope this helps
How much is 4 millimoles of magnesium in mg?
1 Mole of magnesium = 24.305 grams The 24.305 comes from the periodic table of elements. Simply find Mg and the atomic mass (the biggest number) is the same if u have 1 mole of that. So 24.305 grams x 4 = 97.22 grams
