Periodic table of elements
Explanation:
Cr=35.880/51=0.73≈0.7
P=21.076/31=0.67≈0.7
O=43.543/16=2.71
Divide each by 0.7 u get
Cr=1 ,P =1, O=4
Empirical formula is CrPO4
Kepler's Laws of Planetary Motion. While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits.
Sorry about the holds, copied it from google...
I cant answer that if I cant see it
Living things are highly organized and structured, following a hierarchy of scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms combine to form molecules, which are chemical structures consisting of at least two atoms held together by a chemical bond. In plants, animals, and many other types of organisms, molecules come together in specific ways to create structures called organelles. Organelles are small structures that exist within cells and perform specialized functions. As discussed in more detail below, all living things are made of one or more cells.
