How can math tools help you detect errors or inaccuracies in data?
elena-14-01-66 [18.8K]
There are a lot of math tools that can be used to detect inaccuracies of data. Math tools usually used to collect, to organize, to analyse and to present data. Math tools are also used to estimate and find the accurate, precise and signification answers to every study. With Math tools, it is easy to detect if there is inaccurate data, like for example measuring the liquid substances, it needs measuring cup to check if the substance you put is precise.

How many moles of co2 are produced when 5.40 mol of ethane are burned in an excess of oxygen?
Nimfa-mama [501]
<span>Reaction of ethane combustion:

2C2H6 (g) + 7O2 (g) ----> 4CO2 (g) + 6H2O 

According to the reaction, we can see that </span>C2H6 and CO2 have following stoichiometric ratio: 

n(C2H6) : n(CO2) = 2 : 4

If we know the number of moles of ethane we can calculate moles of carbon dioxide:

2 x n(CO2) = 4 x n(C2H6)

n(CO2) = 2 x n(C2H6)

n(CO2) = 2 x 5.4 = 10.8 mole of CO2 <span>are produced</span>

17. When you hold a soda can in your hand, you possess trillions and trillions of aluminum atoms. In one paragraph, using
andreev551 [17]

In the early 1900's, Paul Drüde came up with the "sea of electrons" metallic bonding theory by modeling metals as a mixture of atomic cores (atomic cores = positive nuclei + inner shell of electrons) and valence electrons. Metallic bonds occur among metal atoms. Whereas ionic bonds join metals to non-metals, metallic bonding joins a bulk of metal atoms. A sheet of aluminum foil and a copper wire are both places where you can see metallic bonding in action.

Metals tend to have high melting points and boiling points suggesting strong bonds between the atoms. Even a soft metal like sodium (melting point 97.8°C) melts at a considerably higher temperature than the element (neon) which precedes it in the Periodic Table. Sodium has the electronic structure 1s22s22p63s1. When sodium atoms come together, the electron in the 3s atomic orbital of one sodium atom shares space with the corresponding electron on a neighboring atom to form a molecular orbital - in much the same sort of way that a covalent bond is formed.

The difference, however, is that each sodium atom is being touched by eight other sodium atoms - and the sharing occurs between the central atom and the 3s orbitals on all of the eight other atoms. Each of these eight is in turn being touched by eight sodium atoms, which in turn are touched by eight atoms - and so on and so on, until you have taken in all the atoms in that lump of sodium. All of the 3s orbitals on all of the atoms overlap to give a vast number of molecular orbitals that extend over the whole piece of metal. There have to be huge numbers of molecular orbitals, of course, because any orbital can only hold two electrons.

The electrons can move freely within these molecular orbitals, and so each electron becomes detached from its parent atom. The electrons are said to be delocalized. The metal is held together by the strong forces of attraction between the positive nuclei and the delocalized electrons Hope this helped
