You are giving an unknown element that dull in color. All you have to identify it is an electrical source and a meter that detects electrical charges. You would know it is a nonmetal if you turn on the electrical source and
Answers
Metals conduct electricity while nonmetals do not. Therefore if when you turn on the electrical source and the devise indicates a current, you know the substance is a metal. If you turn on the electrical source and the devise indicates no current, the substance is a nonmetal. I hope this helps. Let me know if anything is unclear.
Olive oil has a density of 0.92 g/mL. How much would 1 liter of olive oil weigh in grams?
Answers
Dimension analysis is to be used to solve this problem. First convert 1L to milliliters. That is equivalent to 1000 ml. Then by dimension analysis, multiply the volume ( 1000ml) to the density of oil (0.92 g/ml) resulting to the answer: 920 grams.

What covalent bond is phosphorus and oxygen
Answers
Covalent bond
When two atoms react, they form either of two kinds of bond, ionic bondsor covalent bonds.Ionic bonds are the type of bonds where there is transfer of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.
Covalent bonds are the kind of bonds formed when two atoms share electrons. Here there is sharing, none of the atoms loses an electron and none gains. A good example is water which is formed when oxygen shares two electrons, each with an atom of hydrogen. The Oxygen atom forms two covalent bonds with the pair of hydrogen atoms.
