What is biopolymer ?​
Greeley [361]

Answer:

Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules. There are three main classes of biopolymers, classified according to the monomers used and the structure of the biopolymer formed: polynucleotides, polypeptides, and polysaccharides.

Explain how acids and bases directly or indirectly affect the hydrogen ion concentration of a solution.
ehidna [41]

By taking hydrogen ions, certain bases directly lower the H+ than OH- concentration. Other bases break down to create hydroxide ions, which indirectly lowers the H+ concentration.

<h3>What is the difference between acid and base?</h3>

H+ ion concentration is raised by an acid. A base is a chemical that, in an aqueous solution, produces hydroxide (OH-) ions, gives electrons, and receives protons. A donor of protons is an acid. A proton can enter a base. When dissolved in water, an acidic chemical compound produces a solution that has more H+ ion activity than clean water. A base is an aqueous material that releases hydroxide (OH-) ions, receives protons, or contributes electrons. A donor of protons is an acid. A base is a proton acceptor.

The symbol that means a substance is a gas is
andrey2020 [161]

(g).

That is the symbol typically put next to elements as a subscript to indicate that an element is a gas.

For instance, H2(g).

Symbols vary for other states of matter and etc.

Hope this helps!

Determine the value of Kp for the following reaction if the equilibrium concentrations are as follows: P(CO)eq = 6.8 × 10-11 atm
Anuta_ua [19.1K]

Answer:

K_{p}=2.7964*10^{20}atm^{-1}

Explanation:

The equilibrium constant Kp is defined as the product of the reaction products partial pressure elevated each one to their respective stoichiometric coefficient divided by the product of the reactants partial pressure elevated each one to its stoichiometric coefficient:

K_{p}=\frac{p_{CO_{2}}^{2}}{p_{CO}^{2}*p_{O_{2}}}

That partial pressures are only at the equilibrium state. So, for this case are the given values:

K_{p}=\frac{0.041^{2}}{({6.8*10^{-11}}) ^{2}*1.3*10^{-3}}=2.7964*10^{20}atm^{-1}
