What is the difference between compound zinc chloride and a mixture of zinc and chlorine?
Compound zinc chloride is a chemical compound where zinc and chlorine atoms are chemically bonded in a fixed ratio. On the other hand, a mixture of zinc and chlorine is a physical combination where zinc and chlorine are simply mixed together without forming any chemical bonds. In the case of a mixture, the components retain their individual properties, whereas in a compound, the properties are different from the individual elements.
Does zinc cream have zinc in it?
Of course it does. It's formulated with zinc oxide.
Is dissolving zinc in acid a physical or chemical property?
Dissolving zinc in acid is a chemical property because it involves a chemical reaction between the zinc and the acid, resulting in the formation of new substances (zinc ions and hydrogen gas) with different properties than the original zinc metal.
Is dissolving zinc in water physical or chemical?
Dissolving zinc in water is a chemical process because the zinc atoms react with the water molecules to form zinc ions and release hydrogen gas. This results in a new substance being formed (zinc ions in water), which is a characteristic of a chemical reaction.
What is the chemical composition of pennies and dimes?
This answer is based on two assumptions: the question is regarding a United States penny and the term 'properties' is directed toward the metallic composition of the coin. According to the U.S. Mint, a penny is made up of 97.5% zinc and only a mere 2.5% copper, the reddish-brown color metal that gives a penny it's distinct appearance.

Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 at 25 is it physical or chemical change?
The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
Is zinc a chemical property?
Zinc is not a property at all; it is a substance. Like all substances it has its own set of physical and chemical properties.
What makes a penny shine?
A penny is made up of metals - copper and zinc both of which have lustrous physical properties
Is mossy zinc is classify as a element or compound?
Mossy zinc is classified as an element because it consists of only one type of atom—zinc. In this case, the atoms are bonded together in a metallic form, which gives mossy zinc its unique physical and chemical properties.

When zinc reacts with acids producing hydrogen gas is it a chemical or physical change?
When zinc reacts with acids to produce hydrogen gas, it is a chemical change because new substances are formed (zinc salts and hydrogen gas) with different properties from the original substances.
What are the two physical properties of zinc iodide?
Examples:- density: 4,74 g/cm3- melting point: 446 oC- crystal structure: tetragonal
