Only a more reactivemetal can displace another out of compound.

Examples of this include the noble (or inert) gases suchas neon or argon.

The high oxygen levels may have turned pyrite on the continents into acid, which increased erosion, flooded essential nutrients, particularly phosphorus, into the oceans, and would have facilitated a huge bloom in the oceans. But this also happened in the midst of Earth's first ice age, so increased glacial erosion may have been primarily responsible, as we will see with a . The two largest carbon-isotope excursions () in Earth's history are related to ice ages. The first was a positive excursion (more carbon-13 than expected), and the second was negative. Scientists are still trying to determine what caused them. Beginning a little less than 2.3 bya and lasting for more than 200 million years is the Lomagundi excursion, in which there was great carbon burial. When the Lomagundi excursion finished, oxygen levels seem to have crashed back down to almost nothing and may have stayed that way for 200 million years, before rebounding to a few percent, at most, of Earth's atmosphere, and it stayed around that low level for more than a billion years.

Reactivity Series Experiment | Reactivity (Chemistry) | Metals

About 2.7 bya, dissolved iron in anoxic oceans seems to have begun reacting with oxygen at the surface, generated by cyanobacteria. The dissolved iron was oxidized from a soluble form to an insoluble one, which then precipitated out of the oceans in those vivid red (the color of rust) layers that we see today and are called ("BIFs"), which became an oxygen sink and kept atmospheric oxygen low. The GOE is widely accepted to have created almost all of the BIFs, but it is not the only BIF-formation hypothesis and there is a great deal of controversy, but life processes are generally considered to be primarily responsible for forming the BIFs. Most iron in the crust is bound in silicates and carbonates, and it takes a great deal of energy to extract the iron from those minerals; the oxides that comprise BIFs are much less energy-intensive to refine, as the iron is so concentrated. Far less ore needs to be melted to get an equivalent amount of iron. BIFs are the source of virtually all iron ore that humans have mined. Life processes almost certainly performed the initial work of refining iron, and humans easily finished the job billions of years later. Copper was not refined by life processes, and copper ore takes twice as much energy to refine as iron ore does.

As told in my plan, more reactive metals will displace less reactivemetals out of compounds.

Experiment faults: The main things that could have affected the
experiment could be contamination of the test tubes if they had not
been cleaned properly and could have other metals inside them this
would of interfered with the results.

Activity Series of Metals - Predicting Reactivity - ThoughtCo

Also to keep the experiment a fairtest
the amount of copper sulphate solution should be kept the same, the
amount of metal should also be kept the same but not the weight it
must be measured in moles.

of Metals * Hypothesis I can predict that a more ..

To carry out this experiment you
will need to follow these steps:

Collect all the necessary apparatus for this experiment these included
the 5 metals, 12 test tubes, 2 test tube racks, 10cm3 of copper
sulphate solution, thermometer and a stopwatch.

The
ease at which elements are willing to give up there spare electrons to
gain a full outer shell is an indication of how reactive that
particular element is, also the ease or difficulty at which the
element is extracted is another indication of how reactive an element
is for example: Magnesium is hard to extract where as gold can be
found in its natural state without anything having to be done to it to
extract it.
