Photosynthesis puts oxygen in the atmosphere.
Answer:thousands of kelvins
Explanation: just got it right on test
The basic repeating unit of nucleic acids are known as nucleotides
The mass percent of oxygen in Barium perchlorate is is 38%.
The molecular mass of Barium perchlorate (Ba(ClO4)2) is 336.2282 g/mol.
Percent composition of Oxygen will be = [(Molecular mass of Oxygen X 8)/ Molecular mass of Barium perchlorate] X 100%
= [(15.99 X 8)/336.2282] X 100% = 38%
