How is this an improvement on the traditional, paper coffee filters? a: they are less wasteful and more cost effective because they last longer b: a permanent filter is more expensive than a traditional filter c: they contain plastic which does not break down as easily as paper d: the coffee brewed using permanent filters does not taste as good?
answer : al
- for a given redox reaction there must be an oxidizing agent/(s) and a reducing agent/(s).
- the oxidizing agent is the substance that undergoes reduction process (gaining electrons or loss of oxygen atoms), meanwhile, the reducing agent is the substance that undergoes oxidation process (loss of electrons or gaining of oxygen atoms).
- in the reaction above, the oxidation number of (al) in alcl3 is (3+). however, the oxidation number of (al) in the products is zero because it exists as a single element.
therefore, changing from (3+) to zero means gaining of (3) electrons to neutralize the previously existing (3) protons on (al) in alcl3.
so al is the oxidizing agent..

mitochondrion. they create oxygen for the cell and is otherwise know as the power house of the cell. rbc’s don’t have them because they would use oxygen that the cell transports
