Which of the following reactions is a synthesis reaction?

1 answer:

5 0

<h3>Answer:</h3>

B) 4H₂(g) + O₂(g) ⟶ 2H₂O(l)

<h3>Explanation:</h3>

Chemical reactions occur when compounds or elements combine to form new compounds or other elements.
Chemical reactions may be classified into various types which include synthesis reactions, replacement reaction, decomposition reactions, and precipitation reactions among others.
In our case, we were supposed to identify a synthesis reaction.
Thus, we need to know what is a synthesis reaction.
A synthesis reaction is a reaction that occurs when two elements or small compounds combine to generate a large compound.
In this case, B is the choice that shows a synthesis reaction where hydrogen gas combines with oxygen gas to yield water.

insulation

surface temperature

Explanation:

ventilation-well ventilated room could increase the body's cooling process

humidity-being in a humid location could cool the body at a slower rate

insulation-a body wrapped in something will cool slower then one not

surface temperature-a body on a hit surface will cool slower than one on a cold surface

The answer is asparagine interactions between aspartate and arginine side chains at neutral pH

<h3>What side chain does arginine have?</h3>

The amino acid arginine has the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.
A guanidino group is attached to a typical amino acid framework in the molecule.
The carboxylic acid is deprotonated (CO2) and both the amino and guanidino groups are protonated, resulting in a cation at physiological pH.
The guanidine group in arginine is the precursor for nitric oxide production. it is a white, water-soluble solid, like all amino acids.
