Write a statement explaining your claim about which experimental setup will dissolve 100 g of
sugar in 1 liter of water at the fastest rate. Next, provide evidence to support your claim about
which setup will result in the fastest rate. Finally, provide reasoning that connects your evidence
to your claim.

Why? Because high-pressure systems don't allow vapor to get high enough to "become clouds," therefore it will not rain. :)

Explanation:

Weathering and erosion on the Earth's surface break down volcanic rock becoming pebbles, sand, as well as mud, resulting in sedimentary rock.

Sedimentary rock, rock generated at or near the Earth's surface as a result of sediment deposition and lithification or precipitation into solution at typical surface temperatures.

Sedimentary rocks are among the most frequent on the Earth's surface, although they make up just a minuscule portion of the crust, which would be dominated by metamorphic and igneous rocks.

Weathering and erosion on the Earth's surface break down volcanic rock becoming pebbles, sand, as well as mud, resulting in sediment that collects in basins just on Earth's surface. The image for the formation of sedimentary rock is given below.

Therefore, weathering and erosion on the Earth's surface break down resulting in sedimentary rock.

Taking into account the definition of molarity, the concentration of the solution is 0.855 [tex]\frac{moles}{liter}[/tex].

Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

[tex]Molarity=\frac{number of moles}{volume}[/tex]

Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].

In this case, you have:

Replacing in the definition of molarity:

[tex]Molarity=\frac{1.71 moles}{2 L}[/tex]

Solving:

Molarity= 0.855 [tex]\frac{moles}{liter}[/tex]

Finally, the concentration of the solution is 0.855 [tex]\frac{moles}{liter}[/tex].

Answer:

Probably because of the dangers

Explanation:

Carbon when emitted causes large damage to the air, so it would be risky because of both the impact on the environment and the consequences the government would give them. It could also be because Carbon isn't durable enough to be burned as a refractory material.

The total volume of water that would be removed will be 75 mL

Using the dilution equation:

M1V1 = M2V2

In this case, M1 = 500 mL, V1 = 10.20 M, M2 = 12 M

Substitute:

V2 = 500 x 10.20/12

         = 425 mL

The final volume in order to arrive at 12 M HNO3 would be 425 mL from the initial 500 mL. Thus, the total amount of water that will be removed by evaporation can be calculated as:

500 - 425 = 75 mL

Answer:

number of moles = 0.21120811

Explanation:

To find the number of moles, given the mass of the solute, we use the formula:

[tex]\mathrm{n = \dfrac{ m }{ M } }[/tex]

[tex]\mathrm{n = number\:of\:moles\:(mol)}[/tex]

[tex]\mathrm{m = mass\:of\:solute\:(g)}[/tex]

[tex]\mathrm{M = molar\:mass\:of\:solute\:( \dfrac{ g }{ mol } )}[/tex]

Label the variables with the numbers in the problem:

[tex]\mathrm{n =\:?}[/tex]

[tex]\mathrm{m =30\:g }[/tex]

[tex]\mathrm{M =\:?\:Calculate\:the\:molar\:mass }[/tex]

The first thing we have to do is find the molar mass of sodium sulfate, in order for us to use the formula for finding the number of moles:

Formula for finding the molar mass of sodium sulfate:

[tex]M({ \left Na \right }_{ 2 } { \left So \right }_{ 4 }) = m \left( Na \right) +m \left( S \right) +m \left( O \right)[/tex]

For the variables and what they mean are below for finding the molar mass of sodium sulfate:

[tex]\mathrm{M =molar\:mass }[/tex]

[tex]\mathrm{m =moles=2\:moles\:for\:Na\:,1\:mole\:for\:S,\:and\:4\:moles\:for\:O}[/tex]

[tex]\mathrm{Na =sodium=22.99\:g }[/tex]

[tex]\mathrm{S =sulfur=32.06\:g }[/tex]

[tex]\mathrm{O =oxygen=16.00\:g }[/tex]

Plug the numbers into the formula, to find the molar mass of sodium sulfate:

[tex]M({ \left Na \right }_{ 2 } { \left So \right }_{ 4 }) = m \left( Na \right) +m \left( S \right) +m \left( O \right)[/tex]

[tex]\mathrm{Substitute\:the\:values\:into\:the\:formula}[/tex]

[tex]M = 2 \left( 22.99 \right) +1 \left( 32.06 \right) +4 \left( 16.00 \right)[/tex]

[tex]\mathrm{Multiply\:2\:by\:22.99\:to\:get\:45.98\:and\:1\:by\:32.06\:to\:get\:32.06}[/tex]

[tex]\mathrm{M = 45.98+32.06+4\:(16)}[/tex]

[tex]\mathrm{Multiply\:4\:by\:16\:to\:get\:64}[/tex]

[tex]\mathrm{M = 45.98+32.06+64}[/tex]

[tex]\mathrm{Add\:45.98\:and\:32.06\:to\:get\:78.04}[/tex]

[tex]\mathrm{M = 78.04+64}[/tex]

[tex]\mathrm{Add\:78.04\:and\:64\:to\:get\:142.04}[/tex]

[tex]\mathrm{M = 142.04}[/tex]

Now that we have found the molar mass, we can calculate the number of moles in the solution of sodium sulfate with the formula:

[tex]\mathrm{n = \dfrac{ m }{ M } }[/tex]

[tex]\mathrm{n =\:?}[/tex]

[tex]\mathrm{m =30\:g }[/tex]

[tex]\mathrm{M = 142.04\:g/mol}[/tex]

[tex]\mathrm{Substitute\:the\:values\:into\:the\:formula}[/tex]

[tex]\mathrm{n = \dfrac{ 30 }{ 142.04 }}[/tex]

[tex]\mathrm{Divide\:142.04\:by\:30\:to\:get\:0.21120811}[/tex]

[tex]\mathrm{n = 0.21120811}[/tex]

0.21120811 rounded gives you 0.2112

or if you did the problem without decimals

30 grams of sodium sulfate divided by its molecular weight – which we found to be 142 – gives us a value of 0.2113 moles.

We see the order with respect to crystal violet (m),but no longer the order with respect to hydroxide (n).

The rate law for the chemical reaction is given as

Rate = k[CV+]m[OH​​​​​-]n,

Because the hydroxide ion conc is an extra of thousand times as massive as the conc of crystal violet, [OH–] will now not exchange drastically all through this experiment.

Answer:

  Field experiments can often have the potential to give scientists opportunities that are not possible in a lab setting.

Explanation:

  Having people "act natural" in a lab setting is impossible to truly achieve, as we all know what happens to our mental state and behavior when we are being actively observed. This is also especially helpful when conducting wildlife research, as there are a myriad of different things influencing animal and plant behavior that would be nigh impossible to recreate perfectly in a controlled lab setting.

  Field research can have its disadvantages as well, as it is very hard to only have one thing change (make an independent variable) in a wild environment with ever-changing weather, social effects, etc. Also, you, as the researcher, as causing an impact on the very location that you are observing, which can alter your results in unpredictable ways.

  The thing to remember is that each type of study has its advantages and disadvantages; if they didn't, then we'd all do the same type of research! You have to weigh your research options and figure out which one works best for your situation :)

Explanation:

2SO2(g) + O2(g) + 2H2O(ℓ) −→ 2H2SO4(ℓ)

We want to find the mass in grams of SO2 that is needed to react with 1527 g of O2. First we must convert the grams of O2 to moles of O2 then to moles of SO2 and then to grams of SO2

So first lets find the molar mass of O2

The mass of oxygen according to a periodic table is 15.999

Using this the mass of O2 would be 15.999(2) = 31.988g

Next we need to identify the mole ratio of O2 to SO2

Looking at the equation for 1 mole of O2 there are two moles of SO2

Next we need to find the molar mass of SO2

Again the mass of oxygen is 15.999g and the mass of Sulfur is 32.066

So the mass of SO2 would be 15.999(2) + 32.066 = 64.064g

Now that we have found all the needed conversions :

We can now use dimensional analysis to calculate the answer.

Kindly check the attached image to see the table. ( sorry if its a bit blurry )
Explanation : The conversions are used to cancel out the units to get to the final unit which is gSO2.

Once the units are cancelled out except for the gSO2 we mutliply and divide based off of what the table says to do.
Here first we divide 1527 by 31.988. We than multiply by 2. Finally we multiply by 64.064 to get the final answer which is 6116gSO2
