Explain each statement in terms of atomic properties:(d) Carbon bonds to itself more extensively than does any other element.
Ket [755]

Carbon forms Covalent bonds rather than ionic bonds.

<h3>About Carbon atom:</h3>

The origin of the name ‘carbon’ is a Latin word ‘carbo’ which means charcoal.

  • it is the fourth most abundant element in the entire universe. And it is the second most abundant element in our bodies after oxygen.
  • The atomic number of carbon is 6.
  • It is represented by the symbol C and is a non-metal.
  • It has 6 protons, 6 neutrons and obviously 6 electrons.
  • carbon atom is considered to be special and unique because it can bond with other carbon atoms to an almost unlimited degree.

<h3>Physical properties of carbon:</h3>

Physical properties of carbon are:

  • The physical properties of this element vary according to its allotropes.
  • The two major allotropes are diamond and graphite.
  • diamond is transparent and has no colour, graphite is opaque and black
  • Diamond is the hardest substance known to man, graphite is soft and spongy in texture
  • diamond cannot conduct electricity at all, graphite is a very good conductor of electricity.
  • Both allotropic elements are solid, non-gaseous
  • Also both diamond and graphite are insoluble in water
  • It does not melt when heated, it sublimes which is it turns to gaseous form
<h3>Uses of carbon in daily life:</h3>
  • It makes up for 18% of the human body.
  • Sugar, glucose, proteins etc. are all made of carbon.
  • The food we eat contains an important source of energy called carbohydrate.
  • Carbon in its diamond form is used in jewellery.
  • Amorphous carbon is used to make inks and paints.
  • It is also used in batteries.
  • Graphite is used as the lead in your pencils.
  • It is also used in the production of steel.
  • One of the most important uses is carbon dating. We can actually use carbon to measure the age of things. Scientists use a rare form of carbon called Carbon-14 to measure the age of fossils, bones etc.
<h3>a) Carbon atoms form covalent rather than ionic :</h3>

  The reason behind the covalent bond is it's tetravalency, that means Carbon has 4 electrons in its valence shell.

Electronic Configuration of Carbon= 1s²2s²2p²

This clearly implies deficiency of 4 electrons to complete its octet .

Now,

In case of formation of ionic bond, gain or loss of electrons takes place.

 So, Carbon has two options either it gain 4 electrons or lose 4 electrons in order to form anion and cation respectively.

Both these possibilities are practically not possible.

Hence, in order to complete octet , Carbon prefers to share 4 electrons with any element rather than to form ion.  And sharing electrons helps both the atoms.

Thus from the above conclusion we can say that, Carbon forms Covalent bonds rather than ionic bonds.

b) Carbon has 4 valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.

 When it bonds only with hydrogen, it forms compounds called hydrocarbons.

 Carbon can form single, double or triple covalent bonds with other atoms in order to complete its octet.

d) The carbon atom is unique among elements in its tendency to form extensive networks of covalent bonds not only with other elements but also with itself. Moreover of all the elements in the second row, carbon has the maximum number of outer shell electrons (four). capable of forming covalent bonds.

 Thus from the above conclusion we can say that, Carbon bonds to itself more extensively than does any other element.

In a 1.0x10^-4 M solution of HClO(aq), identify the relative molar amounts of these species:HClO, OH-, H3O+, OCl-, H2O
yarga [219]
HClO is a weak acid, which means the ions do not fully dissociate. The hydrolysis reaction for the hypochlorous acid is:

HClO + H2O ⇄ H3O+ +OCl-

Then the equilibrium constant, Ka, of dilute HClO would be:

K_{a} = \frac{[ H_{3}  O^{+} ][O Cl^{-} ]}{HClO}

Then we do the ICE table. I is for the initial concentration, C for the change and E for the excess.
      
          HClO       + H2O   ⇄   H3O+ +  OCl-
I     1.0x10^-4                          0             0
C        -x                                 +x           +x 
E  (1.0x10^-4 - x)                     x             x

Substituting the excess (E) concentration to the Ka equation:

K_{a} = \frac{[x ][x]}{1.0 \ x \  10^{-4} - x }

Simplifying the equation would yield a quadratic equation:

x^{2} + K_{a}x-(1.0 \ x \ 10^{-4}) K_{a}=0

The Ka for HClO is an experimental data which was determined to be 2.9 x 10^-8. Substitute this to the equation, determine the roots, then you get the value for x, which is the concentration of H3O+ and ClO-. Just use your calculator feature Shift-Solve.

x = 1.688 x 10^-6 M = [H3O+] = [ClO-]

Then, you can determine the conc of [OH-] through pH.

pH = -log {H3O+] = -log [1.688 x 10^-6] = 5.77
pOH = 14 - pH = 14 - 5.77 = 8.23
pOH = 8.23 = -log [OH-]
[OH-] = 5.89 x 10^-9 M

Also, since HClO is (1.0x10^-4 - x), then it's concentration would be:
[HClO] = 1.0x10^-4 - 1.688 x 10^-6 = 9.83 x10^-5 M

Let's summarize all concentrations:
[HClO] = 9.83 x10^-5 M
[OH-] = 5.89 x 10^-9 M
[H3O+] = [ClO-] = 1.688 x 10^-6 M
Since the solution is dilute, H2O is relatively higher in concentration.

Thus in relative amounts, the order would be

H2O >>> HClO > H3O+ = ClO- > OH-

Based on the given value of the ksp, what is the molar solubility of mg(oh)2 in 0.200 m naoh?
xz_007 [3.2K]
The Ksp refers to the equilibrium constant for a solid dissolving in an aqueous solution.
 Ksp=  5.61×10⁻¹¹  

The equation for this reaction is: 
 Mg(OH)₂ (s) ⇔ Mg²⁺ (aq) + 2 OH⁻ (aq) 

 And the associated equilibrium expression is: 
 Ksp = [Mg2+]  x  [OH–]² 
 Mg(OH)₂ its solid and because of that doesn't have molarity, so its not included.
 
Ksp             = [Mg²⁺]   x   [OH–]²
5.61x10⁻¹¹  = (x) (0.200)² 
x = 1,4025 x 10⁻⁹

If you have a 1.0 L buffer containing 0.208 M NaHSO3 and 0.134 M Na2SO3, what is the pH of the solution after addition of 50.0 m
Vlada [557]

Answer:

pH = 7.233

Explanation:

Initially, the buffer contains 0.208 moles of NaHSO₃ and 0.134 moles of Na₂SO₃.

NaHSO₃ reacts with NaOH thus:

NaHSO₃ + NaOH → Na₂SO₃ + H₂O

50.0 mL of 1.00 M NaOH are:

0.0500L × (1mol / 1L) = 0.0500moles of NaOH added. That means after the addition are produced  0.0500moles of Na₂SO₃ and consumed 0.0500moles of NaHSO₃. That means final moles of the buffer are:

NaHSO₃: 0.208 mol - 0.050 mol = <em>0.158 mol</em>

Na₂SO₃: 0.134 mol + 0.050 mol = <em>0.184 mol</em>

<em> </em>

As pKa of this buffer is 7.167, it is possible to use H-H equation to find pH, thus:

pH = pKa + log₁₀ [Na₂SO₃] / [NaHSO₃]

pH = 7.167 + log₁₀ [0.184] / [0.158]

<em>pH = 7.233</em>

All chemical reactions convert one substance into another. select one:<br> a. true.<br> b. false.
seropon [69]
B. false

All reactions have an equilibrium, at which the rate of the reaction rates on each side of the equation are equal to each other. Sometimes that can be one-way, but it’s more often a two-way street. Where you’ll have an amount of products and reactants.
