The water molecule<span> has two </span>hydrogen<span> atoms joined to one </span>oxygen<span> atom by single covalent bonds. </span>Because oxygen is more electronegative than hydrogen<span>, the electrons of the covalent bond spend </span>more <span>time closer to the </span>oxygen<span> then </span>hydrogen<span> which creates a polar covalent bond. Hope this answers your question. Have a great day!</span>
Answer:
Wavelength of the first four spectral line:
Explanation:
Lman series when electron from higher shell number and jumps to 1st shell then all the possible lines is called as lyman series.
to calculate wavelength of first four spectral line:
For hydrogen Z=1;
by using rydberg equation
![\frac{1}{\lambda} =RZ^2[\frac{1}{n_1^2} -\frac{1}{n_2^2} ]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Clambda%7D%20%3DRZ%5E2%5B%5Cfrac%7B1%7D%7Bn_1%5E2%7D%20-%5Cfrac%7B1%7D%7Bn_2%5E2%7D%20%5D)
1. n=2 to n=1
=rydberg constant
2. n=3 to n=1
3. n=4 to n=1
4. n=5 to n=1
After 4-6 months but i'm happy for you
Richter Scale.
Hope this helps!
The reaction given is:
4Ga + P4 ---> 4GaP
The oxidation number of the reactants is zero, because they are pure elements.
The P in compounds may have oxidation states 3- or 5-. Gallium may only have oxidation state 3+.
Then, to be neutral in GaP the oxidation states are 3+ for Ga and 3- for P.
And the transference of electrons can be see in this oxidation - reduction equations:
Ga (0) - 3 e- ----> Ga (3+)
P (0) + 3e- ---> P (3-)
So, for one formula unit, 3 electrons have been transfered from each Ga atom to P atom to form one GaP unit.
Answer: 3 electrons.
