<span>What are some examples of monomers and oligomers?
</span>Organic molecules, such as proteins, carbohydrates, lipids and nucleic acids, are made of simple subunits called monomers. <span>Plasticizers are </span>oligomeric esters widely used to soften thermoplastics such as PVC and <span>urethane acrylate </span>.
<span>
</span><span>If a chemical compound accelerates and regulates metabolic reactions, which type of role does it play - structural or physiological?
</span>I believe the function that it plays would be physiological since it focuses more on the regulation of the reactions inside the body.

A bond in which one atom contributes both bonding electrons to a covalentbond

yKpoI14uk [10]

<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>

A chemical bond is a force of attraction between two or more atoms of elements.
Covalent bond is a type of chemical bond that occurs between non-metal atoms.
It occurs as a result of sharing of electrons between the non-metal atoms.
Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.

How does an increase in temperature affect the equilibrium concentration of the underlined substance and K for each of the follo

Darya [45]

Explanation:

Due to the positive value of the change in temperature, this is an endothermic reaction.

Since the forward reaction is endothermic, increasing the temperature increases the equilibrium constant (k).

In an equilibrium system, the position of the equilibrium will move in a way to annul the change made to the system. An increase in temperature for an endothermic reaction would favour the reaction, leading to increase in amount of products and decrease in amount of reactants.

If you are given the molarity of a solution, what additional information would you need to find the weight/weight percent (w/w%)

Ludmilka [50]

Answer:

- The molar mass of the solute, in order to convert from moles of solute to grams of solute.

- The density of solution, to convert from volume of solution to mass of solution.

Explanation:

Hello,

In this case, since molarity is mathematically defined as the moles of solute divided by the volume of solution and the weight/weight percent as the mass of solute divided by the mass of solution, we need:

- The molar mass of the solute, in order to convert from moles of solute to grams of solute.

- The density of solution, to convert from volume of solution to mass of solution.

For instance, if a 1-M solution of HCl has a density of 1.125 g/mL, we can compute the w/w% as follows:

$w/w\%=1\frac{molHCl}{L\ sln}*\frac{36.45gHCl}{1molHCl}*\frac{1L\ sln}{1000mL\ sln}*\frac{1mL\ sln}{1.125g\ sln} *100\%\\\\w/w\%=3.15\%$

Whereas the first factor corresponds to the molar mass of HCl, the second one the conversion from L to mL of solution and the third one the density to express in terms of grams of solution.

Regards.
