An example of xenon (Xe)
castortr0y [4]

Answer: i am not sure what you mean but here are some product of xenon stroboscopic lamps, photographic flash lamps, high-intensive arc-lamps for motion picture projection, some lamps used for deep-sea observation, bactericidal lamps, sunbed lamps and high-pressure arc all use this gas. In fact, you probably see xenon lamps on a regular basis and if you want compounds : Xe2F2, XeF4, XeO3, XeF6....

Complete combustion of 1.00 g of the hydrocarbon pagodane gives 3.38 g carbon dioxide. what is the empirical formula of pagodane
Blababa [14]
Combustion of any hrdrocarbon yields carbon dioxide and water such that the hydrogen and carbon are derived from the hydrocarbon. 
1 mole of carbon dioxide has a mass out of which 12 g is the mass of carbon, therefore, 3.38 g of carbon will contain  (3.38 × 12)/44 = 0.922 g of carbon.
Thus, since the hydrocarbon has a mass of 1 g, then the mass of hydrogen will be (1-0.922 g) = 0.078 g.
To get the empirical formula we divide the mass of each element by the atomic mass to get the number of moles.
Carbon= 0.922/12 = 0.0768 moles
Hydrogen = 0.078/1 = 0.078 moles
Then we get the ratio of the moles of carbon : hydrogen
                                                      =   0.0768 : 0.078
                                                         =         1 : 1.016
                                                          ≈        1:   1
Therefore the empirical formula of the hydrocarbon will be CH

Lons form because the loss of one or more electrons makes
ruslelena [56]

This statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.

  • An ion forms when an atom loses or gains one more electrons.
  • This loss or gain of electrons causes the ion to gain the stable octet configuration.
  • This stable octet configuration requires less energy to maintain than the corresponding atom.

So, since the stable octet configuration of the ion requires less energy than the corresponding atom, the statement is false.

So, the statement lons form because the loss of one or more electrons makes them less stable than their corresponding atoms; this state requires more energy to maintain is FALSE.

69g of sodium reacts with chlorine to produce sodium chloride. calculate the number of moles of chlorine required to react with
Rus_ich [418]

Answer:

3 moles of Cl^{-} is needed for Na^{+}to be fully consumed.

Explanation:

For the balanced equation:

                                  Na^{+}  +  Cl^{-}  ⇒  NaCl

First, find the moles of Na corresponding to the 69g used the general definition of mol:

                               mol Na^{+} = \frac{69 g}{23 g/mol }  = 3mol

We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.

According to this, one mole of Na will react with one mole of Cl.

                3 moles of Cl^{-} is needed for Na^{+}to be fully consumed.
