Give an example of traits in a population that have changed in response to an environmental change.
mixer [17]

Answer:

When those traits change over time through many generations in response to changes in environmental conditions, scientists call that process adaptation. In the example of beetle color above, the yellow color trait supported successful survival and reproduction in the new environment.

Procaine hydrochloride (MW = 273) is a 2-ion electrolyte, dissociating 80%. Calculate its dissociation factor. Round to tenths p
Inga [223]

Answer:

Dissociation factor = 1.8

Explanation:

Data provided in the question:

Molecular weight of the Procaine hydrochloride = 273

Number of ions contained, n = 2

Fraction Dissociating, α = 80% = 0.8

Now,

the  dissociation factor 'i' is given as:

i = 1 + α × ( n - 1 )

on substituting the respective values, we get

i = 1 + 0.8 × ( 2 - 1 )

or

i = 1 + ( 0.8 × 1 )

or

i = 1.8

A student needs to prepare a stock solution for the lab - 500.0 ml of 0.750 m nitric acid. The student is provided with concentr
dlinn [17]

Molarity of concentrated nitric acid = 15.9 M

Volume of the stock solution to be prepared = 500.0 mL

Concentration of the stock that is to be prepared = 0.750 M

Calculating moles from molarity and volume of stock:

500.0mL*\frac{1L}{1000mL}*0.750\frac{mol}{L}  =0.375 mol HNO_{3}

Calculating volume of concentrated nitric acid to be taken for the preparation of stock solution:

0.375mol*\frac{1L}{15.9mol} =0.0236 L

Converting L to mL:

0.0236L*\frac{1000mL}{1L} = 23.6 mL

Volume of distilled water to be added to 23.6 mL of 15.9 M nitric acid to get the given concentration = 5000.0mL-23.6mL=976.4 mL

Therefore, 976.4 mL distilled water is to be added to 23.6 mL of 15.9 M nitric acid solution to prepare 500.0 mL of 0.750M nitric acid.
