During the past several lessons you have learned about various processes that change Earth’s surface on different scales. Some e

vents happen quickly, within a fraction of a second, and others take millions to billions of years. Some events are global in scale while others occur on the microscopic level.
Summarize how Earth’s surface has and does change over varying time and spatial (space) scales. Use evidence with examples to support your response.

If you'd like to challenge yourself, use the ABC strategy to summarize how Earth’s surface has and does change over varying time and spatial scales. Each sentence should begin with a word that starts with the letter indicated.

The earth contains a lot of different CLIMATES, in some climates it’s very HOT, the AIR blows through different and that’s what gives states different seasons at different times. the NEWS tracks the climate to let everyone know across the world how it’s gonna be outside. some climates are very dangerous, they can be mixed in with things like GASES that could kill the population, this is why we need to put a end to to the pollution and make the world a better ENVIRONMENT.

gregori [183]

Answer:

Explanation:

Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. Include all free radicals by right-clicking on an atom on the canvas and then using the Atom properties to select the monovalent radical.

Now imagine that you're waiting for your soup to cool down, and you leave it on the counter while you go do your homework. Your
Vlad [161]

Explanation:

Generally, heat flows from a hot environment to a cold (lesser temperature) environment. In this case, the soup is the hot environment and the air is the cold temperature.

Heat would continue to flow from one environment to another until thermal equilibrium is reached. At this thermal equilibrium, both environments would have the same temperature.

A chemistry graduate student is given 125.mL of a 0.20M acetic acid HCH3CO2 solution. Acetic acid is a weak acid with =Ka×1.810−
Over [174]

Answer : The mass of sodium acetate is, 1.097 grams.

Explanation : Given,

The dissociation constant for acetic acid = K_a=1.8\times 10^{-5}

Concentration of acetic acid (weak acid)= 0.20 M

volume of solution = 125. mL

pH = 4.47

First we have to calculate the value of pK_a.

The expression used for the calculation of pK_a is,

pK_a=-\log (K_a)

Now put the value of K_a in this expression, we get:

pK_a=-\log (1.8\times 10^{-5})

pK_a=5-\log (1.8)

pK_a=4.74

Now we have to calculate the concentration of sodium acetate (conjugate base or salt).

Using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[Salt]}{[Acid]}

Now put all the given values in this expression, we get:

4.47=4.74+\log (\frac{[Salt]}{0.20})

[Salt]=0.107M

Now we have to calculate the mass of sodium acetate.

\text{Concentration}=\frac{\text{Mass of }NaCH_3CO_2\times 1000}{\text{Molar mass of }NaCH_3CO_2\times \text{Volume of solution (in mL)}}

0.107M=\frac{\text{Mass of }NaCH_3CO_2\times 1000}{82g/mol\times 125mL}

\text{Mass of }NaCH_3CO_2=1.097g

Therefore, the mass of sodium acetate is, 1.097 grams.
