100 cm^3 of oxygen diffuses through a Porous in 3second how long will it take 150 cm^3 of sulphur (iv) oxide diffuse through the same pot? ( oxygen= 16 sulphur = 32)​

Answers

Answer:

3.18 seconds

Explanation:

Given the following :

Volume of oxygen (V1) = 100cm^3

Time taken (t1) = 3 seconds

Volume of Sulphur (iv) oxide (v2) = 150cm^3

From Graham's Law of diffusion:

(r1/r2) = √(m1/m2)

Where r = rate of diffusion

m = molar mass

Note rate (r) = (volume / time)

[(V1/t1) ÷ (v2/t2)] = √(m1/m2)

(v1/t1) * (t2/v2) = √(m1/m2)

m1 = 02 = (16 * 2) = 32

m2 = SO2 = (32 + (16 * 2)) = 64

(100/3) * (t2/150) = √(32/64)

100t2 / 450 = √(32/64)

100t2 / 450 = √32 / 8

100t2 / 450 = √32 / 8

100t2 * 8 = 450 * √32

800t2 = 2545.5844

t2 = 2545.5844 / 800

t2 = 3.1819805

t2 = 3.18 seconds

It will take 3.18s for 150cm^3 of Sulphur (iv) oxide to diffuse through the same pot.

If the molarity of sugar is 1.1, what will the freezing point be?

Answers

Answer:

The freezing point will be -2.046°C.

Explanation:

The freezing point depression equation is [tex]\Delta T_f = k_f \cdot m \cdot i[/tex]

Where;

[tex]\Delta T_f[/tex] = The temperature depression of the freezing point

[tex]k_f[/tex]= The constant of freezing point depression which is solvent dependent = 1.86°C/m

i = The number of particles the substance decomposes into in solution = 1 for sugar (a covalent compound)

m = The molality of the solution = 1.1

Therefore, we have;

[tex]\Delta T_f = 1.86 \times 1.1 \times 1 = 2.046 ^{\circ}C[/tex]

Therefore the freezing point will be 0 - 2.046°C = -2.046°C.

how much of the excess reactant remains unchanged?
how much N2 is formed? (in mol)
how much H2O is firmed? (in mol)

Answers

Answer:

1. The limiting reactant is H2O2.

2. The amount of excess reactant, N2H4 that remain unchanged is 11.15 moles.

3. 1.65 moles of N2.

4. 6.6 moles of H2O.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

N2H4 + 2H2O2 —> N2 + 4H2O

From the balanced equation above,

1 mole of N2H4 reacted with 2 moles of H2O2 to produce 1 mole of N2 and 4 moles of H2O.

1. Determination of the limiting reactant.

From the balanced equation above,

1 mole of N2H4 reacted with 2 moles of H2O2.

Therefore, 12.8 moles of N2H4 will react with = 12.8 x 2 = 25.6 moles of H2O2.

From the calculations made above, we can see that it will take a higher amount i.e 25.6 moles than what was given i.e 3.3 moles of H2O2 to react completely with 12.8 moles of N2H4.

Therefore, H2O2 is the limiting reactant and N2H4 is the excess reactant.

2. Determination of the excess reactant that remain unchanged.

The excess reactant is N2H4.

First, we shall determine the amount of the excess reactant that reacted. This is illustrated below:

From the balanced equation above,

1 mole of N2H4 reacted with 2 moles of H2O2.

Therefore, Xmol of N2H4 will react with 3.3 moles of H2O2 i.e

Xmol of N2H4 = (1 x 3.3)/2

Xmol of N2H4 = 1.65 moles

Therefore, 1.65 moles of N2H4 reacted.

Now, we shall determine the excess reactant that remain unchanged. This can be obtained as follow:

Amount of N2H4 given = 12.8 moles

Amount of N2H4 that reacted = 1.65 moles.

Amount of N2H4 that remain unchanged =?

Amount of N2H4 that remain unchanged = (Amount of N2H4 given) – (Amount of N2H4 that reacted = 1.65 moles)

Amount of N2H4 that remain unchanged = 12.8 – 1.65

Amount of N2H4 that remain unchanged = 11.15 moles.

3. Determination of the amount of N2 produced.

In this case, the limiting reactant will be used because it will give the maximum yield of N2 as all of it is used up in the reaction.

The limiting reactant is H2O2 and the amount of N2 produced can be obtained as follow:

From the balanced equation above,

2 moles of H2O2 reacted to produce 1 mole of N2.

Therefore, 3.3 moles of H2O2 will react to produce = (3.3 x 1)/2 = 1.65 moles of N2.

Therefore, 1.65 moles of N2 were obtained from the reaction.

4. Determination of the amount of H2O produced.

In this case, the limiting reactant will be used because it will give the maximum yield of H2O as all of it is used up in the reaction.

The limiting reactant is H2O2 and the amount of H2O produced can be obtained as follow:

From the balanced equation above,

2 moles of H2O2 reacted to produce 4 moles of H2O.

Therefore, 3.3 moles of H2O2 will react to produce = (3.3 x 4)/2 = 6.6 moles of H2O.

Therefore, 6.6 moles of H2O were produced from the reaction.

The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The specific heat capacity of a certain substance has been measured to be 3.52 J/g °C. Suppose 420.0 g of the substance is heated until the temperature of the sample has changed by 43.8 °C.
Write an equation that will let you calculate the last Q that was needed for this temperature change. Your equation should contain only symbols. Be sure to define each symbol.

Answers

Answer:

The answers to your questions are given below.

Explanation:

Data obtained from the question include:

Mass (M) = 420.0 g

Temperature change (ΔT) = 43.8 °C

Specific heat capacity (C) = 3.52 J/g °C

Heat needed (Q) =...?

The heat needed for the temperature change can be obtained by using the following formula:

Q = MCΔT

Where:

Q is the heat needed measured in joule (J).

M is the mass of substance measured in grams (g)

C is the specific heat capacity of the substance with unit J/g °C.

ΔT is the temperature change measured in degree celsius (°C).

Thus, we can calculate the heat needed to change the temperature as follow:

Q = MCΔT

Q = 420 x 3.52 x 43.8

Q = 64753.92 J

Therefore, the heat needed to cause the temperature change is 64753.92 J

What wavelength measures
A. Depth
B. Distance
C. Energy
D. Speed
E. Time
F. Volume

Answers

Answer:

Distance.

Explanation:

Wavelength (λ) can be defined as the distance between two successive crest or trough of a wave.

From the above definition, wavelength (λ) simply measures distance.

This can further be explained by obtaining the unit of measurement for wavelength (λ).

This can be illustrated below:

Wavelength is related velocity and frequency according to the following equation:

Velocity (v) = wavelength (λ) x frequency (f)

v = λf

λ = v/f

Velocity is measured in ms¯¹

Frequency is measured in hertz, Hz (s¯¹)

λ = v/f

λ = ms¯¹ / s¯¹

λ = m

We can see that wavelength is measured in metre (m) which is the same unit for measuring distance.

Therefore, wavelength measures distance.

In the lab, Amanda has two solutions that contain alcohol and is mixing them with each other. She uses twice as much Solution A as Solution B. Solution A is 11% alcohol and Solution B is 18% alcohol. How many milliliters of Solution B does she use, if the resulting mixture has 320 milliliters of pure alcohol?

Answers

Answer:

1,103.47 milliliters

Explanation:

The total percentage of alcohol from solution A and solution B is 29. In a solution that is a mixture of solution A and B, the percentage of alcohol that would be contributed by solution A would be:--

                   11/29 x 100% = 37.93%

--while the percentage of alcohol that would be contributed by solution B would be:

               18/29 x 100 = 62.07%

Hence, if a mixture of A and B has 320 milliliters of alcohol, the amount of alcohol contributed by B would be:

                     320 x 62.07/100 =  198.624 milliliters

Now, remember that solution B is 18% alcohol. This means that the 18% alcohol content of solution B is 198.624 milliliters. Thus, the total volume of solution B would be:

                 198.624 x 100/18 = 1,103.47 milliliters.

Therefore, the total milliliters of solution B Amanda used would be 1,103.47.

How many moles of potassium in 73.56g of potassium chlorate (V) (KClO 3 )?

Answers

Answer:

Approximately [tex]0.6003\; \rm mol[/tex] formula units.

Explanation:

Formula Mass of KClO₃

Look up the relative atomic mass data for [tex]\rm K[/tex], [tex]\rm Cl[/tex], and [tex]\rm O[/tex] on a modern periodic table:

[tex]\rm K[/tex]: [tex]39.908[/tex].[tex]\rm Cl[/tex]: [tex]35.45[/tex].[tex]\rm O[/tex]: [tex]15.999[/tex].

The relative atomic mass of an element is numerically equal to the mass (in grams) of one mole of its atoms. For example, the relative atomic mass of [tex]\rm K[/tex] is [tex]39.908[/tex]. Therefore, the mass of one mole of [tex]\rm K\![/tex] atoms should be [tex]39.908\; \rm g[/tex].

Each [tex]\rm KClO_3[/tex] "formula" unit includes one [tex]\rm K[/tex] atom, one [tex]\rm Cl[/tex] atom, and three [tex]\rm O[/tex] atoms. Therefore, one mole of [tex]\rm KClO_3\![/tex] formula units would include:

one mole of [tex]\rm K[/tex] atoms, one mole of [tex]\rm Cl[/tex] atoms, and three moles of [tex]\rm O[/tex] atoms.

From the relative atomic mass of these three elements:

The mass of one mole of [tex]\rm K[/tex] atoms would be [tex]39.908\; \rm g[/tex].The mass of one mole of [tex]\rm Cl[/tex] atoms would be [tex]35.45\; \rm g[/tex].The mass of three moles of [tex]\rm O[/tex] atoms would be [tex]3 \times 15.999\; \rm g = 47.997\; \rm g[/tex].

Combining these three parts should give the mass of one mole of [tex]\rm KClO_3[/tex] formula units:

[tex]\begin{aligned}& M(\mathrm{KClO_3}) \\ &= 39.908 + 35.45 + 3 \times 15.999 \\ &= 122.545\; \rm g \cdot mol^{-1}\end{aligned}[/tex].

Number of moles of KClO₃ formula units in the sample

The formula mass of [tex]\rm KClO_3[/tex] is [tex]M(\mathrm{KClO_3}) = 122.545\; \rm g \cdot mol^{-1}[/tex], meaning that the mass of one mole of [tex]\rm KClO_3\![/tex] formula units would be [tex]122.545\; \rm g\![/tex].

The mass of this [tex]\rm KClO_3\!\![/tex] sample is [tex]m(\mathrm{KClO_3}) = 73.56\; \rm g[/tex]. The number of moles of formula [tex]\rm KClO_3\![/tex] units in this sample would be:

[tex]\begin{aligned}n(\mathrm{KClO_3}) &= \frac{m(\mathrm{KClO_3})}{M(\mathrm{KClO_3})} \\ &= \frac{73.56\; \rm g}{122.545\; \rm g \cdot mol^{-1}} \approx 0.6003\; \rm mol\end{aligned}[/tex].

73.56 g of potassium chlorate (v), KClO₃ contains 0.6 mole of potassium, K.

To know the exact number of mole of potassium (K) in 73.56 g of potassium chlorate (v), KClO₃ do the following:

Step 1:

Determination of the number of mole in 73.56 g of potassium chlorate (v), KClO₃

Mass of KClO₃ = 73.56 g

Molar mass of KClO₃ = 39 + 35.5 + (16×3)

= 39 + 35.5 + 48

= 122.5 g/mol

Mole of KClO₃ =?

[tex]Mole =\frac{mass}{molar mass}\\\\Mol KClO_{3} = \frac{73.56}{122.5}[/tex]

Mole of KClO₃ = 0.6 mole

Step 2:

Determination of the number of mole of potassium, K in 0.6 mole (i.e 73.56 g) of KClO₃

Considering the molecular formula of potassium chlorate (v), KClO₃, we can see that:

1 mole of KClO₃ contains 1 mole of K.

Therefore, 0.6 mole of KClO₃ will also contain 0.6 mole of K.

Therefore, we can conclude that 73.56 g of KClO₃ contains 0.6 mole of potassium, K.

you just got home from a run on a hot Atlanta afternoon. you grab a 1.00-liter bottle of water and drink three-quarters of it in one swig. How many moles of water did you consume?

Answers

Answer:

41.67 mol

Explanation:

1 Litre of water = 1000g

Mole = mass / molar mass

Mass of 1 L of water = 1000 g

Molar mass of water (H2O) :

(H = 1, O = 16)

H2O = (1 * 2) + 16 = (2 + 16) = 18g/mol

Amount of water consumed = (3/4) of 1 litre

= (3/4) * 1000g

= 750g

Therefore mass of water consumed = 750g

Mole = 750g / 18g/mol

Mole of water consumed = 41.6666

Round your answer to 2 decimal places.) find the value of x? please help If you are flying over a mountain and see sedimentary layers making an outline in the shape of an overturned cereal bowl, the feature would be called a(n) Bighorn sheep are beautiful wild animals found throughout the western United States. Data for this problem are based on information taken from The Desert Bighorn, edited by Monson and Sumner 9University of Arizona Press). Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information:x 1 2 3 4 5y 14 18.9 14.4 19.6 20.0x=15 ; y=87.3;x2=55; y2=1569.77; xy=275(a) Draw a scatter diagram.(b) Find the equation of the least-squares line, and plot the line on the scatter diagram of part (a).(c) Find the correlation coefficient r. Find the coefficient of determination . What percentage of variation in y is explained by the variation in x and the least squares model?
