Answer:

Gravity drives all mass wasting.

Explanation:

Mass wasting can be defined as the process of wasting away of earth's outer crust. This movement is also known as slope movement that causes large rock, soil, and debris to move downward, a force driven by gravity.

The term is often used interchangeably with landslide yet it is different. It is also known as mass movement as is cause massive downslope movement of rock, regolith, snow, ice, and-the-like on the earth's outer crust.

<u>All these movements are driven mainly by gravity. Gravity consantly tries to pull the rocks and soil down the slope but the resisting power. also known as shear strength, of moutains helps them to deny the gravitional force.</u>

Thus from the given options the statement that can be said to be true about mass wasting is that mass wasting is driven by gravity. So, the correct option is C.

All the following involve an increase in entropy except O most endothermic reactions O sublimation O vaporization O combustion
daser333 [38]

Answer:

most endothermic reactions

Explanation:

In endothermic reactions, the entropy of the environment decreases.

The entropy is the measure of the disorder of a specific system.

An endothermic reaction is every chemical reaction in which energy is absorbed.

In a comparison of an endodermic reaction in which energy is released in light or heat form.

Kc for the reaction of hydrogen and iodine to produce hydrogen iodide.
tatiyna

Answer:

[H_2]_{eq}=0.183M

[I_2]_{eq}=0.183M

[HI]_{eq}=0.025M

Explanation:

Hello.

In this case, for this equilibrium problem, we first realize that at the beginning there is just HI, it means that the reaction should be rewritten as follows:

2HI\rightleftharpoons H_2+I_2

Whereas the law of mass action (equilibrium expression) is:

Kc=\frac{[H_2][I_2]}{[HI]^2}

That in terms of initial concentrations and reaction extent or change x turns out:

Kc=\frac{x*x}{([HI]_0-2x)^2}\\\\54.3=\frac{x^2}{(0.391M-2x)^2}

And the solution via solver or quadratic equation is:

x_1=0.183M\\\\x_2=0.210M

Whereas the correct answer is 0.183 M since the other value yield a negative concentration of HI at equilibrium (0.391-2*0.210=-0.029M).This, the equilibrium concentrations are:

[H_2]_{eq}=0.183M

[I_2]_{eq}=0.183M

[HI]_{eq}=0.391M-2*0.183M=0.025M

Regards.

If 4.50 g of (nh4)2so4 is dissolved in enough water to form 250. ml of solution, what is the molarity of the solution?
natima [27]
The molarity of a solution is the number of moles of a substance in one liter of that substance. 
The molar mass of ammonium sulfate (NH4)2SO4 is 132.14 grams/mole
Calculate the moles of ammonium sulfate:
(4.50 grams)/(132.14 grams/mole) = 0.0341 moles of ammonium sulfate
convert mL to Liters 250. mL becomes 0.250 liters
Take the number of moles over the number of liters
0.0341 moles / 0.250 liters = 0.136 molar or 0.136M = molarity of the solution
