Which option should a person avoid doing in order to better protect the quality of watersheds?
Norma-Jean [14]

"People should remove native plants around watersheds" option should a person avoid doing in order to better protect the quality of watersheds.

<u>Option: A</u>

<u>Explanation:</u>

Watershed is basically a source of large amount of water like river, sea, etc to another location like lake, ponds and stream.This is seen majorly during rainy season by water harvesting to supply further for farming, portable water plant, manufacturing sectors, enrich habitat to number of plants and animals, etc. Waterways face issues when erosion, pollutants and runoff of animal waste take place, which act as barrier for water flow, as it decreases the quality which affect aquatic animals life, reduce oxygen content. Native plants near watersheds is also a habitat for many animals and species thus it should not be removed until some major flaw occurs.

A student plans to add HCL to a solution containing pb(NO3)2 (aq). To determine how much Pb2+ will precipitate from solution whe
WINSTONCH [101]

Answer:

Option C. Ksp for PbCl₂

Explanation:

The equilibrium constant that is established between a solid and its ions in a saturated solution is what is known as Ksp (solubility product). It is an equilibrium constant based on concentrations.

The concentrations must be equilibrium, that is, concentrations of the ions in a saturated solution. To be sure of such saturation it is convenient to form a precipitate.

The smaller the Kps, the more insoluble the salt

6) (a) Calculate the absorbance of the solution if its concentration is 0.0278 M and its molar extinction coefficient is 35.9 L/
Anvisha [2.4K]

Answer:

6) (a) 0.499; (b) 31.7 %

7) 0.15

Explanation:

6) (a) Absorbance

Beer's Law is

A = \epsilon cl\\A = \text{35.9 L&\cdot$mol$^{-1}$cm$^{-1}$} $\times$ 0.0278 mol$\cdot$L$^{-1} \times $ 0.5 cm = \mathbf{0.499}

(b) Percent transmission

A = \log {\left (\dfrac{1}{T}}\right)}\\\\\%T = 100T\\\\T = \dfrac{\%T}{100}\\\\\dfrac{1}{T} = \dfrac{100 }{\%T}\\\\A = \log \left(\dfrac{100 }{\%T} \right ) = 2 - \log \%T\\\\0.499 = 2 - \log \%T\\\\\log \%T = 2 - 0.499 = 1.501\\\\\%T = 10^{1.501} = \mathbf{31.7}

7) Absorbance

A = \log \left (\dfrac{I_{0}}{I} \right ) = \log \left (\dfrac{I_{0}}{0.70I_{0}} \right ) = \log \left (\dfrac{1}{0.70} \right ) = -\log(0.70) = \mathbf{0.15}}

I’ll $ashapp anyone who knows the answers to these!!! Leave your $tag
kvv77 [185]

Answer:

below

Explanation:

1. The areas that have latitudes which are closer to the equator are generally hotter than those areas that are closer to the north and south poles.

2. Temperature is inversely related to latitude, as latitude increases from the equator (moving north or south) the temperature decreases.

Hope this helps! best of luck <3
