Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.. As we saw earlier, oxygen plays the role of an oxidizer in the combustion reaction, but any chemical species that can replicate that role is a possible substitute for oxygen. Body Fat Percentage vs. The atmosphere is a mixture of many gases. The amount o f oxygen in the atmosphere is about 21% and all living beings use oxygen present in the atmosphere for breathing. Figure 1: Crucible set-up. For instance, if you had a 80.0 g sample of a compound that was 20.0 g element X and 60.0 g element y then the percent composition of each element would be: Review the procedures of the test and learn why it is performed.
