Fatima is designing an advanced graphics card for a next-generation video game system. She needs to be able to precisely control the conductivity of the electronic components. For this purpose, she should use materials that are .

An element that is likely to have this property is
.

In an oxidation-reduction reaction, oxidation is what happens when a reactant

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.
