Write down the group numbers for carbon,oxygen,nitrogen and sulphur ​

Chemistry
1 answer:
Bess [88]3 years ago
5 0

Answer:

Carbon - 14

Oxygen - 16

Nitrogen - 15

Sulphur - 16

Explanation:

The question above is related to the "Periodic Table of Elements" which shows the proper arrangement of elements in a table. Every element falls on a<em> group/family</em> within the table. Each group has its own number, and the table has a total of<u> 18 groups</u><em> (from left to right). </em>They are classified according to <em>similarities in their characteristics</em>. For example, group 1 is composed of <em>alkali metals</em> while group 2 is composed of<em> alkali earth metals</em>.

Helium is a colourless, odorless used in bolloons. Calculate . the pressure Cin atm) exerted by 1.82 mous of gas in a steel vess
loris [4]

Answer:

9.59 atm

Explanation:

Use ideal gas law    PV = n RT

 V = 5.34 L    n = 1.82 mole   T = ( 69.58+ 273.15) = 342.73 K

         R = .082057  L-Atm/(K - mole)

P  = n RT / V = 9.59 Atm

Is nuclear waste and radioactive waste the same thing?
ElenaW [278]

Answer: yes

Explanation: Radioactive (or nuclear) waste is a byproduct from nuclear reactors, fuel processing plants, hospitals and research facilities. Radioactive waste is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities. There are two broad classifications: high-level or low-level waste.

Construct a simulated proton-decoupled 13C NMR spectrum for tert-butyl alcohol. Drag the resonance signal icon to the appropriat
atroni [7]

Answer:

                     The ¹³C-NMR Spectrum of  <em>tert</em>-butyl alcohol will show only two signals.

(i) Signal at around 31 ppm:

                                              This signal towards upfield is for the carbon atoms which are more shielded and are having rich electron surroundings. The height of peak at y-axis shows the number of carbon atoms as compared to other peaks. In this case it is three times the height of second signal hence, it shows that this peak corresponds to three carbon atoms.

(ii) Signal at around 70 ppm:

                                              This signal towards downfield is for the carbon atom which is more deshielded and is having electron deficient surrounding. As compared to the second signal the height of this peaks corresponds to only one carbon. And the deshielded environment shows that this carbon is directly attached to an electronegative element.

In addition to those in Table 14.3, other less stable nitrogen oxides exist. Draw a Lewis structure for each of the following:(c
Natalka [10]

Lewis structure for each of the following N₂O₃ with no N¬N bond is attached below.

Even though pi symmetry occupies the antibonding orbitals of NO, this is unimportant after the dimer forms. A sigma connection exists. The enthalpy of the newly formed sigma bond in the dimer is low because the loss of a particularly distinctive set of single-electron resonance forms that were available for no monomer offset the net gain in bond. When the whole free energy is taken into account, there is no gain because the entropic effects are on the order of 1030kJ/mol, and dimerization is entropically disfavored at G=17kJ/mol. Therefore, any little increase in enthalpy is cancelled out by the loss of entropy.
