Answer: d. smaller.
Explanation:
Hybridization :
![N=\frac{1}{2}[V+N+A-C]](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN%2BA-C%5D)
N = number of electrons
where, V = number of valence electrons present in central atom i.e. oxygen = 6
N = number of monovalent atoms bonded to central atom=32
C = charge of cation = 0
A = charge of anion = 0
The number of electrons is 4 that means the hybridization will be
and the electronic geometry of the molecule will be tetrahedral. The bond angle for tetrahedral geometry is 
But as there are two atoms around the central oxygen, the third and fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent and the bond angle will be smaller than expected and is 
To find the wavelength of an electromagnetic wave for the given frequency can be determined by using the formulaSpeed=Wavelength x FrequencyWavelength=Speed/FrequencyGenerally Speed of the electromagnetic wave is 3x10^8 m/sBy substituting the values Wavelength=3x10^8 m/s / 2.63x10^12 s^-1Wavelength=1.14 x 10^-4 metres
Answer:
Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure
Explanation:
The configuration of these elements is as follows;
Cl₁₇ = 2, 8,7 (the outer electron is 7)
Ca₂₀ = 2,8,8,2 (the outer electron is 2)
Ne₁₀ = 2,8 (the outer electron is 8)
Na₁₁ = 2,8,1 (the outer electron is 1)
Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.
Answer:
Equal
Explanation:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
