Cooks use baking soda to make cakes light and fluffy. You might have used baking soda yourself. Baking soda is NaHCO3. A 0.1 M s

olution of baking soda and water has a [H+] of about 4.0 X 10^-9. (You may prefer to think of the Hydronium ion concentration, [H3O+], as 4.0 X 10-9.) write the formula for the calculation of pH, and then show each job as you calculate the pH of 0.1 M solution of baking soda.,

Answer is: pH = 8,046.<span>
c(H</span>₃O⁺) = 4·10⁻⁹ M = 4·10⁻⁹ mol/L = 0,000000004 mol/L.<span>
pH = -logc(H</span>₃O⁺).<span>
pH = -log(</span>4·10⁻⁹ mol/L<span>).
pH = -(-8,046) = 8,046.
When pH is less than seven (pH<7), solution is acidic.
When is equal seven (pH = 7), solution is neutral.
When pH is greater than seven (pH > 7), solution is basic </span>(like this example).

Phosphorus can be stable with 12 electrons in its valence structure while nitrogen can never have more than 8 electrons in its v
dolphi86 [110]

Here we have explain that the maximum possible electrons present in nitrogen valence shell is 8 whereas in phosphorous 12 valence electrons are present.

Although both nitrogen (N) and phosphorous (P) belongs to the same series there are several properties which are different between both the element. The number of electrons present in nitrogen is seven which are present in the -s and -p orbitals. The electronic configuration of nitrogen is 1s²2s²2p³. In which the outermost electrons are the valence electrons i.e. 5 valence electrons are present. The maximum orbitals are possible under the principal quantum number 2 are -s and -p orbitals. Now the maximum capacity of the p orbital to contain 6 electrons, as it is half filled in nitrogen another 3 electrons can be incorporated. Thus the maximum number of electrons can be present in nitrogen is 10 among which 8 is the valence electrons.

On the other hand there are 15 electrons in phosphorous the electronic configuration is 1s²2s²2p⁶3s²3p³. Now the principal quantum number 3 can have three orbitals -s, -p and -d. So another 13 electrons can be incorporated (3 in -p orbital and 10 in -d orbital) among which upto 12 electrons can be its valence electrons.

Why are the alloys harder than pure iron
balu736 [363]

Answer:

ok

Explanation:

Alloys are harder and stronger because the different-sized atoms of the mixed metals make the atomic layers less regular, so they cannot slide as easily.
