Answer:

Time = 8.12 h = 0.34 day

Explanation:

First we find speed of water flow:

Speed = u = (3160 tons/s)(907.185 kg/1 ton)

u = 2866704.6 kg/s

also,

Density = (1 g/mL)(1 mL/1 x 10⁻⁶ m³)(1 x 10⁻³ kg/1 g)

Density = 1000 kg/m³

Now,

Volume Flow Rate = Speed/Density

Volume Flow Rate = (2866704.6 kg/s)/(1000 kg/m³)

Volume Flow Rate = 2866.7 m³/s

Now, we find volume of cylinder:

Volume = (Area)(Length)

Volume = (πd²/4)(L)

Volume = [(π)(0.53 m)²/4][236000 mi][1609.36 m/1 mi]

Volume = 83,792,823.82 m³

Now,

Time = Volume/Volume Flow Rate

Time = (83,792,823.82 m³)/(2866.7 m³/s)

Time = (29299.71 s)(1 h/3600 s)

<u>Time = 8.12 h = 0.34 day</u>

Calculate the net change in enthalpy for the formation of one mole of nitric acid from nitrogen, hydrogen and oxygen from these
deff fn [24]
The formation of nitric acid from nitrogen, hydrogen, and oxygen can be written as,

     N₂ + H₂ + 3O₂ --> 2HNO₃

The net enthalpy of formation of nitric acid is calculated by,
   Hrxn = Hproduct - Hreactant

Since all the reactants are in their elemental forms, the simplified equation would be,

    Hrxn = Hproduct 

Substituting,

    Hrxn = (-186.81 kJ/mol)(2 mols)

<em>Answer: -372.42 kJ</em>

How acidic buffer resist change in pH on addition of acid and base.
andrew-mc [135]

Answer:

Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].

hope it's help
