These artificial homes preserve the resources in the animal's environment and increases population size.
<h3>What is Population size?</h3>
This is defined as the number of organisms in a population at a given place and time.
Since the resources used are artificial, they are preserved with an increase in the population due to reproduction.

<span>Most fertilizer bags are marked with three numbers, which represent the amounts of the following chemicals: nitrogen, phosphorus, and potassium. The third number represents the amount of potassium in the fertilizer. All three of these chemicals are important for plants, but different plants require different amounts of these chemicals, so the label helps consumers determine which product to buy.</span>
To get the ratio of the concentration of sodium acetate to the concentration of acetic acid we are going to use H-H equation:
when:
PH = Pka + ㏒[salt/acid]
when the Ka of acetic acid = 1.75 x 10^-5
so, we can get Pka from this formula:
Pka = -㏒Ka
= -㏒1.75 x 10^-5
= 4.76
and when we have PH = 5.75, so by substitution:
∴ 5.75 = 4.76 + ㏒[acetate/ acetic acid]
∴ [acetate/acetic acid] = 9.77
∴ the ratio of a concentration of acetate to acetic acid 9.77
Answer:
Molar mass of monoprotic acid is 1145g/mol.
Explanation:
The reaction of a monoprotic acid (HX) with NaOH is:
HX + NaOH → H₂O + NaX
That means 1 mole of acid reacts with 1 mole of NaOH
If the neutralization of the acid spent 20.27mL of a 0.1578 M NaOH solution. Moles of NaOH are:
0.02027L × (0.1578mol / L) = <em>3.199x10⁻³ moles</em> NaOH ≡ moles HX.
As mass of the sample is 3.664g, molar mass of the acid is:
3.664g / 3.199x10⁻³ moles =<em> 1145g/mol</em>
