Answer:

32.711

Explanation:

1 yard = 0.0009144 km

1 week = 168 hrs

6.01 x 10^6 / 168 = 35,773.81 yds/hr

                            =  32.711 km/hr

Consider the reaction: 2HI(g) ⇄ H2(g) + I2(g). It is found that, when equilibrium is reached at a certain temperature, HI is 35.
Sliva [168]

Answer:

Kc = 0.075

Explanation:

The dissociation (α) is the initial quantity that ionized divided by the total dissolved. So, let's calling x the ionized quantity, and M the initial one:

α = x/M

x = M*α

x = 0.354M

For the stoichiometry of the reaction (2:1:1), the concentration of H₂ and I₂ must be half of the acid. So the equilibrium table must be:

2HI(g) ⇄   H₂(g) +    I₂(g)

M               0             0               <em> Initial</em>

-0.354M  +0.177M  +0.177M       <em>Reacts</em>

0.646M     0.177M   0.177M        <em>Equilibrium</em>

The equilibrium constant Kc is the multiplication of the products' concentrations (elevated by their coefficients) divided by the multiplication of the reactants' concentrations (elevated by their coefficients):

Kc = \frac{[H2]*[I2]}{[HI]^2}

Kc = \frac{0.177M*0.177M}{(0.646M)^2}

Kc = \frac{0.03133M^2}{0.41732M^2}

Kc = 0.075

What do you expect from a hurricane?
blsea [12.9K]
Depending in the category of the Hurricane, you make experience different levels of wind power and destruction. Hurricanes only have 5 categories ranking from Category 1 to Category 5. The smallest category is category 1 making category 5 the largest. The bigger the category, the more wind or destruction you'll experience.
