How do you write the formula for zinc sulfate?
ZnSO₄Zinc sulfate / Formula
What is the formula of zinc sulphate in Criss Cross method?
The chemical or molecular formula of Zinc Sulfate is ZnSO4.
What is the valency of ZnSO4?
Answer: Zinc is a d-Block element and belongs to Transition Metal. Valence shell contains 2 electrons that is 4s2 that means that zinc can lose the two electrons located in the 4s-orbital to be become the Zn2+ cation. So, the valency of Zinc is 2.
What is the name for ZnS?
Zinc sulfide
Zinc sulfide (ZnS), a naturally occurring salt, is the main source of zinc. It has two common crystalline forms (polymorphs): Sphalerite (“zinc blende”), with a cubic crystal structure, is the form that predominates in nature.
How do you make formula using Criss Cross method?
An alternative way to writing a correct formula for an ionic compound is to use the crisscross method. In this method, the numerical value of each of the ion charges is crossed over to become the subscript of the other ion. Signs of the charges are dropped. Write the formula for lead (IV) oxide.

How do you calculate zinc volume?
The density of zinc listed is 7.140 g/mL,. Meaning that 7.140 grams of zinc displaces 1 mL of water. 20 grams/7.140 grams scales this by a factor of 2,8 so that 20 grams displaces 2,8 mL of water and the volume of zinc metal required for this reaction is 2.8 cubic centimeters.

What is the mass and volume of zinc?
The thing to remember about a substance’s density is that it tells you the mass of exactly 1 unit of volume that substance occupies. In this case, you know that the density of zinc is equal to 7.1 g cm−3 , which means that 1 cm3 of zinc will have a mass of 7.1 g .
