Answer:

The salinity of the sea decreases due to an increase in fresh water in the ocean from the melting of the polar ice caps.

Explanation:

Ocean water can become saltier or fresher depending on environmental factors.

Melted ice, fresh water, will decrease the salinity of the oceans. That is, the process of oceanic desalination or decrease in salinity, known as freshening, is generated by the discharge of fresh water from the ice of glaciers into the salty water of the seas that surround it.

The order of a reaction Z1) is the product of the powers to which the reactant concentrations are raised in the rate law. Z2) ca

irinina [24]

Explanation:

The Order of Reaction refers to the power dependence of the rate on the concentration of each reactant.

The overall order of reaction is the sum of the individual orders of reaction with respect to the reactants.

Rate = k [A]²[B]¹

In the rate law above, the rate is second order with respect to A and first order with respect to B. The overall order of reaction is a third order reaaction given as; 2+ 1 = 3

| A solution containing 4.48 ppm KMnO4 exhibits

Artist 52 [7]

Answer:

Molar absorptivity or molar extinction co-effecient = 2120.14 cm⁻¹M⁻¹

Explanation:

First convert Concentration from ppm inM or mol/l

⇒ Molar mass of KMnO₄ = 158.03 g

⇒ 4.48 ppm = 4.48 mg/l = 4.48 x 10⁻³ g/l

⇒ Molarity = $\frac{4.48 X10^{-3} }{158.03X 1(lit)}$ = 2.83 x 10⁻⁵ molar

Absorbance (A) = - log(T) ( T = % transmittance)

= - log(0.859)

= 0.06

According to Lambert Beer's law

ε = $\frac{A}{C X l}$

or, ε = $\frac{0.06}{2.83 X 10^{-5}X1 cm }$

or, ε = 2120.14 cm⁻¹M⁻¹

Where

ε = Molar absorptivity

A = absorbance

C = Molar concentration of KMnO₄ solution

l = length
