Q.1) Tap water conducts electricity whereas distilled

2012-6-14 · Tap water contains minerals; the main ones are salts, calcium, magnesium, strontium, ferrous iron, and manganese. These are the substances in tap water that conduct electricity. Tap water actually produces electrolytes, which means the water molecules break down the minerals into ionic form, giving them the ability to conduct electricity.

Electrical Conductivity of Metals - The Balance

Electrical conductivity in metals is a result of the movement of electrically charged particles. The atoms of metal elements are characterized by the presence of valence electrons, which are electrons in the outer shell of an atom that are free to move about. It is these ''free electrons'' that allow metals to conduct …

Anodizing of Aluminum

Why Does Solid Sodium Conduct Electricity? | …

The delocalized electrons can carry an electric current, thus allowing solid sodium to conduct electricity. Sodium is a metal. Its outermost shell or energy level has only one electron. Each sodium atom is surrounded by eight other sodium atoms, each of which has one electron in its outermost energy level.

Minerals in Water | Water Mineral Levels | DrinkMore …

Do I actually want minerals in my water? A great question. Let’s start with what exactly are minerals? Minerals are inorganic substances (such as rocks and similar matter) found in the earth strata, as opposed to organic substances such as plant and animal matter. Some familiar minerals are what we think of as “good minerals” – things like calcium, magnesium and potassium.

Ionic solids conduct electricity in molten state but not i

Hello Students Ionic solids contains ions holder together with strong electrostatic force together and thus do not conduct electricity in lid form. In molten state, these ions dissociate in water and are free to conduct electricity.

Answers | Yahoo Answers

Best answer: Formula mass is the addition of all the atomic mass nuer of the constituent elements in that molecule. for example water H20 is 18. Hydrogen is 1, oxygen is 16. In a question like this. you would probably be given grams of a certain element. you divide that nuer by the formula mass and you get moles. to get nuer of molecules, you multiply moles by 6.02 X 10 to the 23rd power.
