Which of these events is caused by contact forces?
harkovskaia [24]

Earthquakes along the San Andreas fault in California.

<u>Explanation</u>:

  • When the two plates collide with each other, earthquakes occur. The contact between them makes this earthquake possible. The contact forces are responsible for the earthquakes as there is contact between two plates.          
  • The gravitational force is a force that is responsible for elevated tides happening on the east coast or the Jupiter's moons to remain in orbit. But this is not a contact force as there is no contact between them
  • Moreover, Without any contact, the magnetic force is a non-contact as it attracts the pins from a distance.

What is cloud ? How does it affect on weather ?​
Lapatulllka [165]

Clouds are xondense form of water vapour over dust particles present in the upper atmosphere.

It effects the weather as when the clouds get heavy they get precipitate in the form pf rain, snow, hail. because of these factors temperature goes down and make us feel cold.

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
