While hiking last year, Mike saw a large boulder next to a mountain trail. The boulder had no cracks. While hiking on the trail

this year, he saw two large cracks in the boulder.
Which of the following most likely caused these cracks to form?
Shaking from high winds.
Pressure from flowing water.
Erosion due to falling rain and snow.
Weathering due to freezing and thawing.

Answer: weathering due to freezing and thawing

Explanation:

The reason that caused these cracks to form is weathering due to freezing and thawing.

Weathering simply means the breaking down of rocks. In this situation, the boulder is freezed and thawed and due to this, as time progresses, it'll gradually be broken down. This is the reason why Mike saw the cracks even though there were no cracks the last time he went hiking.

Solar energy will not run out (unless the sun burns out), but the supply of fossil fuels we use is slowly depleting. Burning fossil fuel also releases greenhouse gas into the air, which is bad for the atmosphere.

A. Based on the activation energies and frequency factors, rank the following reactions from fastest to slowest reaction rate, a
deff fn [24]

Answer:

A) E_{a} = 350KJ/mol, E_{a} = 50KJ/mol, E_{a} = 50KJ/mol

     A = 1.5×10^{-7}s^{-1}, A = 1.9×10^{-7} s^{-1}, A=1.5×10^{-7} s^{-1}

B) 4.469

Explanation:

From Arrhenius equation

      K=Ae^{\frac{E_{a} }{RT} }

where; K = Rate of constant

            A = Pre exponetial factor

            E_{a} = Activation Energy

             R = Universal constant

             T = Temperature in Kelvin

Given parameters:

E_{a} =165KJ/mol

T_{1}=505K

T_{2}=525K

R=8.314JK^{-1}mol^{-1}

taking logarithm on both sides of the equation we have;

InK=InA-\frac{E_{a} }{RT}

since we have the rate of two different temperature the equation can be derived as:

In(\frac{K_{2} }{K_{1} } )=\frac{E_{a} }{R}(\frac{1}{T_{1} } -\frac{1}{T_{2} } )

In(\frac{K_{2} }{K_{1} } )=\frac{165000J/mol}{8.314JK^{-1}mol^{-1}  }.(\frac{1}{505} -\frac{1}{525} )

In(\frac{K_{2} }{K_{1} } )= 19846.04×7.544×10^{-5} = 1.497

\frac{K_{2} }{K_{1} } =e^{1.497} = 4.469

In what applications might coal replace petroleum based fuel
JulsSmile [24]
Coal can replace petroleum base fuel when you are just heating something that dont need big amount of heat. examples of it is when producing steam, coal is just used to heat water and produce steam because coal is much cheaper and the coal can already do the job in heating the water
