Com: if a protein contains 150 amino acids, there would be how many codons in the specification to construct it?

1 answer:

8 0

If a bacterial protein contains 150 amino acids, then there would be 150 codons in the specification to construct the said protein. A codon is definces as a sequence of 3 RNA or DNA nucleotides which would correspond to a specific amino acid such that if you have 150 amino acids then you would also have 50 codons. THe start of a codon is the first codon that can be found in the messenger RNA that is translated by the ribosome.

All of the following undergo hybridization except <br><br> A. C<br> B. Si<br> C. Mg<br> D. B

Pavel [41]

Answer:

C: Mg

Explanation:

Hybridization of atomic orbitals is a fundamental concept introduced by Pauling that describes the mixing of orbitals at an atom which adds a definite direction to the Lewis - shared electron pair or electron chemical - bond concept.

Carbon(C) can hybridized on sp, sp2 and sp3 simply because it's valence shell gives room for it.

For silicon(si), when forming covalent bonds with other atoms, it's 3s and 3p orbitals are mixed with each other to form new hybrid orbitals.

Magnesium in itself doesn't hybridized except in magnesium hydrides.

Boron orbitals(B): when boron forms bonds with three other atoms like borazine, they are hybridized to either the sp2 or hybridized to the sp3 which occurs when boron forms bonds with four atoms just as is in metal borohydrides.

vekshin1

<h2>Answer : Option C) Joseph is observing the color of the reaction mixture to see whether proteins are present in the given solution.</h2><h3>Explanation :</h3>

An example of qualitative observation is the one where one uses the five senses to identify the changes in the reaction.

Here, when Joseph is studying a reaction mixture he is trying to observe a color change which will confirm that there is proteins present in the reaction mixture or not If there is a color change observed then it will confirm the presence of proteins.

Usually qualitative observations are those which can be easily predicted by using five senses.

From the reaction: B2H6 + O2 HBO2 + H2O a. What mass of O2 will be needed to burn 36.1 g of B2H6? b. How many moles of water are

steposvetlana [31]

A. The mass of O₂ needed to burn 36.1 g of B₂H₆ is 123.77 g

B. The number of mole of water, H₂O produced from 19.2 g of B₂H₆ is 1.372 mole

<h3>Balanced equation </h3>

B₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O

Molar mass of B₂H₆ = (2×11) + (1×6) = 28 g/mol

Mass of B₂H₆ from the balanced equation = 1 × 28 = 28 g

Molar mass of O₂ = 2 × 16 = 32 g/mol

Mass of O₂ from the balanced equation = 3 × 32 = 96 g

SUMMARY

From the balanced equation above,

28 g of B₂H₆ required 96 g of O₂

<h3>A. How to determine the mass of O₂ needed </h3>

From the balanced equation above,

28 g of B₂H₆ required 96 g of O₂

Therefore

36.1 g of B₂H₆ will require = (36.1 × 96) / 28 = 123.77 g of O₂

Thus, 123.77 g of O₂ is required for the reaction

<h3>B. How to determine the mole of water produced </h3>

We'll begin by calculating the number of mole of in 19.2 g of B₂H₆. This can be obtained as follow:

Mass of B₂H₆ = 19.2 g
Molar mass of B₂H₆ = 28 g/mol
Mole of B₂H₆ =?

Mole = mass / molar mass

Mole of B₂H₆ = 19.2 / 28

Mole of B₂H₆ = 0.686 mole

Finally, we shall determine the number of mole of water produced. This is illustrated below:

<h3>Balanced equation </h3>

B₂H₆ + 3O₂ —> 2HBO₂ + 2H₂O

From the balanced equation above

1 mole of B₂H₆ reacted to produce 2 moles of H₂O

Therefore, H₂O

0.686 mole of B₂H₆ will react to produce = 0.686 × 2 = 1.372 mole of H₂O

Thus, 1.372 mole of H₂O was obtained from the reaction

Bent, the lone pair on the central atom push away the other atoms and the most stable configuration of the lone pair and two atoms is trogonal planar. But since you cannot see the lone pair, the shape of the three atoms is bent.
