Astudent currently is averaging 65.0% of the points in lecture and has a 75.0% in lab. what is her total course % at this time? (the letter grade can also be determined. look at the greensheet for your chem 1a lecture to see what letter grade this student would get. thus when you get a percent score on a test or any other graded work and you want to know the letter grade for it, go look at the lecture greensheet! ) group of answer choices

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
