Which is the best way to determine if an object is made of pure silver? O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.

C. Determine the density of the object and compare the known density of pure silver.

Explanation:

A pure silver is a chemical substance that comprises of 0.1% of trace elements and 99.9% of silver. It is also known as fine silver in chemistry.

Due to the fact that pure silver has a very high level of purity, it is usually too soft for jewelry making and as such it's mixed with other metals such as copper, nickel, zinc, palladium etc. so as to make it hard.

In Chemistry, the best way to determine if an object is made of pure silver is to determine the density of the object and compare the known density of pure silver. This can be done by properly weighing the object to determine its mass and then determining its volume by checking how much water is displaced when completely immersed. The respective values for mass and volume of the object is then used to calculate its density.

Density can be defined as mass all over the volume of an object. Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

After determining the density of the object, it is then compared with the density of pure silver which is ideally 10.5g/cm³.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
