What is the approximate energy of a photon having a frequency of 4 x 10^7 Hz? (h = 6.6 x 10^-34 J . s)
BigorU [14]

Answer:

2.64 ×10^{-26} J

Explanation:

I think you should mark it a physics question instead but anyway.

---------------------------------------------------------------------------

The Planck equation should be applied:

E = hv , while E is energy of proton; h is Planck constant; and v is frequency.

E = 6.6 × 10^{-34} × 4 × 10^{7}

  = 6.6 × 4 × 10^{-27}

  = 2.64 ×10^{-26} J

Which is a genotype?
Pani-rosa [81]

Answer:

Genotypes are related with the collection of genes expressed in the DNA.

Explanation:

Hello,

In genetics, two specific terms define the characteristics of a living thing; a genotype and a phenotype; thus, phenotypes are related with the physical manifestation of genes, for instance, red hair, blue eyes, long arms and others.

On the other hand, genotypes are related with the collection of genes expressed in the DNA, and they could be for equal alleles or for different alleles, in other words, it is the version of DNA the living thing has.

Regards.

Methane (CH4) is a gas that is found in small quantities in earths atmosphere. which type of bonds does methane have and why doe
OLga [1]

Answer:

Methane is a covalent bond. Methane is a chemical compound from the bonding  one carbon atom and for hydrogen atoms. Although electronegativity increases as you go right of the periodic table, hydrogen has an electronegativity of 2.20. Chlorine has an electronegativity of 2.55. There difference in electron negativity (0.34). Therefore it is a non polar compound. If there difference was much greater, than they would form a ionic bond. Alkali metals tend to form the most ionic bond, but although hyrdogen is placed with them, it has a higher electronegativity so hydrogen is an exception.

Carbon has 4 valence electrons so it will want to gain 4 more electrons to become stable (Octet rule). Hydrogen has 1 valence electron, so it will want to lose it to become stable. Therefore, one carbon atom takes 1 electrons from 4 hydrogen atoms.
