Which Act is the set of laws signed by former President Nixon that helps keep water clean in the United States?
otez555 [7]

Clean Water Act

Explanation:

The Clean Water Act in 1972 was a set of laws signed by former President Nixon that helps to keep water clean in the United States.

  • The act sets a safe limit for the amount and kind of pollutants that can be released into the water that won't contaminate it.
  • The acts charged the Environmental Protection Agency(EPA) to set a safe limit for nature and amount of pollutants that can be released into the water.
  • This act is one of the several environmental polices in the United States that ensures a safe drinking water is available.

In this reaction, a gaseous system with a volume of 3.00 L has a rate of formation of NOCl of 0.0120 M s-1 . The volume of the s
oee [108]

Answer:

x = 0.324 M s⁻¹

Explanation:

Equation for the reaction can be represented as:

 2 NO(g)   + Cl₂ (g)      ⇄     2NOCl (g)

Rate = K [NO]² [Cl₂]

Concentration = \frac{numbers of mole (n)}{volume (v)}

from the question; their number of moles are constant since the species are quite alike.

As such; if Concentration varies inversely proportional to the volume;

we have: Concentration ∝ \frac{1}{v}

Concentration = \frac{1}{v}

Similarly; the Rate can now be expressed as:

Rate = K [NO]² [Cl₂]

Rate = (\frac{1}{v}) ^2 (\frac{1}{v} )

Rate = \frac{1}{v^3}

We were also told that the in the reaction, the gaseous system has an initial volume of 3.00 L and rate of formation of 0.0120 Ms⁻¹

So we can have:

0.0120 = \frac{1}{3^3}

0.0120 = \frac{1}{27}   -----Equation (1)

Now; the new rate of formation when the  volume of the system decreased to 1.00 L can now be calculated as:

x = (\frac{1}{1})^3

x = 1             ------- Equation (2)

Dividing equation (2) with equation (1); we have:

\frac{0.0210}{x} = \frac{\frac{1}{27} }{1}

\frac{0.0210}{x} = \frac{1}{27}

x = 0.0120 × 27

x = 0.324 M s⁻¹

∴  the new rate of formation of NOCl = 0.324 M s⁻¹
