Zn plus MgCl2 yields what?
The reaction between zinc (Zn) and magnesium chloride (MgCl2) would yield zinc chloride (ZnCl2) and magnesium (Mg).

Would MgCl2 be classified as ionic or covalent?
MgCl2 is classified as ionic. It is a metal and a non metal.
Is zncl2 a salt?
Yes, ZnCl2 (zinc chloride) is a salt. It is an inorganic compound composed of a metal cation (Zn2+) and a non-metal anion (Cl-), which are held together by ionic bonds.
What mass of zinc metal is required to produce 2.40g of zinc chloride?
To calculate the mass of zinc metal required to produce zinc chloride, you need to find the molar mass of zinc chloride (ZnCl2). The molar mass of ZnCl2 is 136.3 g/mol, which means that for every mole of ZnCl2 produced, you need 1 mole of zinc metal. Since 1 mole of ZnCl2 corresponds to 2 moles of zinc (from the formula ZnCl2), the mass of zinc metal required is 2.40g * (65.38 g Zn/ 136.3 g ZnCl2) = 1.15g.
Does ZnCl2 react with dilute HCl?
No, ZnCl2 does not react with dilute HCl because ZnCl2 is already a product of the reaction between zinc metal and HCl. So, no further reaction occurs when ZnCl2 is added to dilute HCl.
Is 2Zn plus HCl equals ZnCl2 plus H2 a redox reaction?
yes as zinc is oxidised and hydrogen is reduced
Why is MgCl2 added to a solution of EDTA?
MgCl2 is added to a solution of EDTA to prevent the formation of insoluble metal hydroxides when titrating with EDTA. This helps to ensure that the EDTA only chelates with the target metal ions in the solution without interference from other metal hydroxides. MgCl2 acts as a masking agent for other metal ions present in the solution.
Zinc metal reacts with hydrochloric acid?
yes, with the formation of zinc chloride - ZnCl2.
What is the equation when zinc metal is added to a solution of copper II chloride?
The chemical equation for the reaction that occurs when zinc metal is added to a solution of copper II chloride is: Zn + CuCl2 -> Cu + ZnCl2.
