Write the formula of hydrochloric acid which liberated hydrogen gas when reacting with magnesium metal?
The formula of hydrochloric acid is HCl. When it reacts with magnesium metal, it forms magnesium chloride (MgCl2) and hydrogen gas (H2) according to this equation: 2HCl + Mg → MgCl2 + H2.
What is the chemical formula for a compound between Mg and Cl?
Mg has a positive 2 charge ( wants to give away 2 electrons). Cl has a negative one charge (wants to gain an electron). Since it is a bond between a non metal and metal it is a ionic bond, therefore you cross the charges. Your answer should be: MgCl2 (where the two is written as a subscript of Cl and we don't write one because it is 'understood' )
How do you write the formulae of aluminum chloride?
The formula for aluminum chloride is AlCl3. This formula indicates that each molecule of aluminum chloride contains one aluminum atom and three chlorine atoms.
How do you calculate what mass of magnesium chloride is formed when 54.75g of HCl is reacted with sufficient magnesium?
By starting with a balanced equation. Mg + 2HCl -> MgCl2 + H2 when they say sufficient magnesium they imply that magnesium is in excess and HCl limits and drives the reaction, or that both are equal in molarity/mass 54.75 g HCl (1 mole HCl/36.458 g)(1 mole MgCl2/2 mole HCl)(95.21 g/1 mole MgCl2) = 71.49 grams magnesium chloride produced -----------------------------------------------------------
How do you write zinc chloride as a chemical formula?
ZnCl2. Zinc has a positive 2 charge and chloride has a negative 1 charge. You balance the charges of zinc and chloride and you get ZnCl2
Write a correct formula for calcium chloride?
The correct formula for calcium chloride is CaCl2, which signifies that one calcium atom is bonded to two chloride atoms.
What is the correct way to write magnesium oxide?
Did you want the formula? If so it is MgO.
Why is it not possible to write a correct chemical formula for the compound copper chloride?
It is indeed possible to write a correct chemical formula for copper chloride, which can exist in two primary forms: copper(I) chloride (CuCl) and copper(II) chloride (CuCl₂). The difference arises from the oxidation states of copper; in CuCl, copper has a +1 charge, while in CuCl₂, it has a +2 charge. Therefore, the appropriate formula depends on the specific oxidation state of copper being referred to.
Write the formula of hydrochloric acid which liberated hydrogen gas when reacting with magnesium metal?
The formula of hydrochloric acid is HCl. When it reacts with magnesium metal, it forms magnesium chloride (MgCl2) and hydrogen gas (H2) according to this equation: 2HCl + Mg → MgCl2 + H2.
What is the chemical equation for magnesium plus chlorine?
Magnesium has a charge of +2 and Chloride has a charge of -1. In order to make magnesium chloride have a net charge of zero, there must be twice as much of the chloride ion than the magnesium ion. The ratio of magnesium to chloride is therefore 1:2. With this knowledge, we can write the chemical equation MgCl2.
Write the chemical formula for calcium chloride?
The chemical formula for calcium chloride is CaCl2 - Ca++ ionically bonded with 2 Cl-.
