I WILL GIVE BRAINLEIST/ Use the visual and the table to answer the question. A black and white rock with no shine is shown. The rock appears to have a rough texture. (Item Mohs Hardness fingernail 2.5 penny 3 knife 5.1 steel nail 6.5 ) You have found the mineral shown in the picture. A knife won’t scratch it, but a nail will. Describe at least four properties that would help you identify the mineral.

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
