Use the electron-transfer method to balance this equation: solid copper and dilute nitric acid react to produce copper(ii) nitrate, water, and nitrogen monoxide gas (no)

Asingle atom of an element has 21 neutrons, 20 electrons, and 20 protons. which element is it? ok o z

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
