What is true when an element is oxidized?

1.  Reacts with oxygen

2. Loss electrons

3. Reduce the element that oxidizes it.

Explanation:

Oxidation is a phenomenon in which an element or compound reacts with oxygen, producing an oxide (in case of metals).

Although strictly speaking, oxidation refers to the chemical process that involves the loss of electrons by a molecule, atom or ion.

If this element participate in a redox reaction when oxidized it is reducing the element that oxidizes it.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
