Its energy : 1.193 x 10⁻¹⁹ J
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
Four different groups attached to it. A chiral carbon is an asymmetric carbon.
Enantiomers are a pair of stereoisomer molecules that are chiral. For an example, I have attached an image of a chiral carbon below.
Question: <em>What is the hybridization of each carbon and oxygen atoms in vitamin C?</em>
Answer:
1. To decide the hybridization of a carbon, look at how many atoms are attached to it (including the hydrogens that may be unwritten). If there are 4 total atoms attached (all with single bonds), the carbon must have sp3 orbitals (there are 4 of them). If 3, then sp2. If 2, then sp. Carbon can't be sp3d or sp3d2 hybridized because carbon is in the 2nd period of the periodic table and doesn't possess any d orbitals to hybridize.
2. Not sure what this question means. Did you mean to type just C-C bonds? If so, just count the number of bonds between 2 carbon atoms!
3. Use VSEPR. The bond angle is as great as possible, based on the repulsion of the valence electron pairs (both bonded and lone). This is also related to hybridization. sp3 hybrid orbitals are 109.5 degress apart, sp2 is 120, sp is 180.
4. See part 1. Determine the hybridization of both C4 and C5. The overlap of an orbital from each carbon is what forms the sigma bond.
<span> Speicific heat of water is 4.2j/gm*C </span>
<span>Thus 4.2 Joules of energy is required to heat 1 gm water to 1*C. </span>
<span>or 4.2 x 30 Joules enery is required to heat 1x30 gm water by 1*C </span>
<span>or 4.2 x 30 x 80 Joules enery is required to heat 1 x 30 gm water by (100-20)*C( or required to be removed from water to cool it) </span>
