My physics teacher had us write this down last week.

The mass of sucrose that is hydrolyzed when 2.60 l of a 0.160 m sucrose solution is allowed to react for 200 minutes is 106 g.

The following information in the complete question;

Rate constant (k) = 1.8 x 10^-4 s^-2

Initial concentration (Ao) = 0.130 M

Time is taken =  190 minutes or 11400 seconds

Final concentration (A) =?

Given that;

lnA = lnAo - kt

A = e^ lnAo - kt

A = e^[(ln0.130) - ( 1.8 x 10^-4  x  11400)

A = 0.017 M

Now;

n = CV

n = Number of moles

C = Molar concentration

V = volume

After hydrolysing the number of moles = 0.017 M ×  2.75 L

= 0.047 moles

Before hydrolysing number of moles =0.130 M  ×  2.75 L = 0.358 moles

Hydrolysed number of moles include=  0.358 moles - 0.047 moles = 0.311 moles

Mass = Number of moles × molar mass

Molar mass of sucrose = 342 g/mol

Mass =   0.311 moles × 342 g/mol

Mass = 106 g

Answer:

981.82g or 0.982 kg

Explanation:

I believe this is Physics, but okay!

We have to use the Specific Heat Capacity formula here.

Heat energy = mass x specific heat capacity x change in temperature

mass = Heat energy/(specific heat capacity x change in temperature)

Heat energy is measured in Joules so we need to find out how to do this.

To find an amount in Joules, we are given 135g and 0.89J/g°C.

135g x 400°C = 54000 to give us g°C

54000 x 0.89 = 48060  By multiplying these two values, we get given 48060J.

This is because: g°C/1 x J/g°C = Joules on it's own

mass = (48060)/[0.89 x (80 - 25)]

mass = 981.82g

2moles of H2O are made when 6moles of HNO3 are consumed

75 mole of HNO3 produces = \(\frac{2}{6}\)× 75 ⇒ 25 moles of water

The limiting reagent is the reactant that is completely used up in a reaction and thus determines when the reaction stops.

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O

6 mole of HNO3 produces \(\frac{2}{6}\) = 2 moles of H₂O

1 mole of HNO3 produces =  mole of H₂O

∴ 75 mole of HNO3 produces = \(\frac{2}{6}\) × 75 ⇒ 25 moles of water

Answer:

0.18 moles

Explanation:

Applying,

PV = nRT................... Equation 1

Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = temperature.

make n the subject of the equation

n = PV/RT............... Equation 2

Given: V = 5.3 L, T = 22 °C = (22+272) K = 295 K, P = 632 mmHg = (0.00131579×632) = 0.8316 atm,  R = 0.083 L.atm/K.mol

Substitute these values into equation 2

n = (0.8316×5.3)/(0.083×295)

n = 0.18 moles

The hh genotype gives rise to the Bombay phenotype.

The Bombay phenotype, also known as the hh phenotype, is a genetic condition that results from a specific combination of alleles at the H blood group locus. People with the Bombay phenotype have a genotype of hh, meaning they do not produce the H antigen on their red blood cells. This can have significant implications for blood transfusions, as the lack of H antigen on the surface of red blood cells can cause a potentially life-threatening reaction when transfused with blood from someone who is an H antigen secreter (i.e., has an HH or Hh genotype).

Therefore, the hh genotype gives rise to the Bombay phenotype, characterized by the absence of the H antigen on red blood cells.

The rate of heat input required to operate an on-demand water heater, ensuring all the heat goes into the water without wastage, depends on the flow rate and the temperature rise needed.

Conventional hot-water heaters with a tank maintain a fixed temperature, resulting in heat loss when not in use and the possibility of running out of hot water. On the other hand, on-demand water heaters, also known as flash heaters, eliminate the need for a water tank and prevent heat wastage.

To determine the rate of heat input required for an on-demand water heater, two factors need to be considered: the flow rate of the water and the desired temperature rise. In this case, the flow rate is given as 7.43 liters per minute (or 759 ml/min), and the temperature rise is from 10.°C to 47°C.

To calculate the heat input, we can use the formula:

Heat Input = Flow Rate × Specific Heat Capacity × Temperature Rise

The specific heat capacity of water is approximately 4.18 Joules per gram per degree Celsius.

Converting the flow rate to grams per minute (1 liter of water = 1000 grams), we have:

Flow Rate = 7.43 liters/min × 1000 grams/liter = 7430 grams/min

Substituting the values into the formula, we get:

Heat Input = 7430 grams/min × 4.18 J/g°C × (47°C - 10°C)

Simplifying the equation:

Heat Input = 7430 × 4.18 × 37 Joules per minute

Therefore, the rate of heat input required for the on-demand water heater is 11,270.14 Joules per minute.

Spectrophotometer measures the amount of light absorbed or reflected by a sample solution.

A spectrophotometer is a device used to measure the amount of light a sample solution absorbs or reflects.

It works by shining a beam of light onto a sample solution and then measuring the intensity of the light that is reflected or absorbed.

The light used is typically in the visible spectrum, such as white light, but may also include ultraviolet or infrared light, depending on the application.

The intensity of the light is usually measured in terms of percent transmission or percent reflectance.

To measure the amount of light absorbed or reflected, the sample is placed into a cuvette, a special container designed to hold samples for spectrophotometry.

The light is then shined through the cuvette and onto a detector, which measures the intensity of the light that passes through the sample.

The detector then produces a numerical reading that is directly proportional to the amount of light absorbed by the sample.

The two reasons the fossil found on vega island is of particular importance to understanding the climate and location of Antarctica millions of years ago are Isotopic composition and Paleoclimate proxies

Isotopic composition: The isotopic composition of rocks and residue in Antarctica can uncover significant hints about past climate and temperature conditions.

For instance, the proportion of isotopes, for example, oxygen and hydrogen can give data about the temperature of the climate when the stone or silt was framed.

This data can be utilized to decide if Antarctica was situated in a warm or cold climate a long period of time prior and how the climate has changed over the long run.

Paleoclimate proxies: Paleoclimate proxies are indirect indicators of past climate conditions and are many times found in silt and rock deposits.

For instance, dust grains can demonstrate the sorts of plants that existed in a specific region and the climate conditions they expected to develop. Essentially, the presence of specific minerals, like calcite or aragonite, can give data about the temperature and saltiness of the water in which they are framed.

By examining these proxies, researchers can recreate past climate conditions in Antarctica and gain a superior comprehension of how the climate has changed after some time.

Answer:

number of moles of CO2 is 0.054

number of moles of CO is 0.107

number of moles of O2 remaining is 0.01 mole

mole fraction of CO is 0.63

Explanation:

Firstly, we write the equation of reaction;

3C(s) +2O2(g) → CO2(g) +2CO(g)

Now, we proceed.

From the written equation, we can deduce that

3 mol C = 2 mol O2 = 1 mol CO2 = 2 mol CO

No of mol of C reacted = 0.161 mol

limiting reactant according to the question is Carbon

a. no of mol of CO2 formed = 0.161*1/3 = 0.054 moles ( no of moles of CO2 formed is one-third of no of moles of carbon reacted. This is obtainable from their mole ratio 1:3)

b. no of mol of CO formed = 0.161*2/3 = 0.107 mol

c. no of mol of O2 remaining = 0.117 - (0.151*2/3) = 0.117-0.107 = 0.01 mole

d. mole fraction of CO = no of mol of CO/Total number of moles

= 0.107/(0.107+0.054+0.01)

= 0.625730994152 which is approximately 0.63

The number of moles of CO₂, CO, and O₂ formed is 0.054, 0.107, and 0.01 mole respectively.

And the mole fraction of CO is 0.63

The equation of reaction is given as the following:

3C(s) +2O₂(g) → CO₂(g) +2CO(g)

from above we can say that the number of moles required for the reaction to proceed is:

3 mol of C

2 mol of O₂

1 mol CO₂, and

2 mol CO

so the ratio is:

C:O₂:CO₂:CO = 3:2:1:2

Given that the number of mol of C produced is 0.161 mol

(i) number of mol of CO₂ formed = 0.161 × 1/3 = 0.054 moles

(ii) number of mol of CO formed = 0.161 × 2/3 = 0.107 mol

(iii) number of mol of O₂ remaining = 0.117 - (0.151 × 2/3)

                                                          = 0.117 - 0.107

                                                          = 0.01 mole

(iv) mole fraction of CO = (number of mol of CO) / (Total number of moles)

                                       = 0.107 / (0.107+0.054+0.01)

                                       = 0.63

Answer:

The volume at STP is 41.3mL

Explanation:

To solve this question we must find the volume using the combined gas law. The equation is:

P1V1 / T1 = P2V2 / T2

Where P is pressure, V volume and T absolute temperature of 1, initial state and 2, final state of the gas.

P1 = 718torr

V1 = 47.9mL

T1 = 26°C + 273.15 = 299.15K

P2 = 760torr at STP

V2 = ?

T2 = 273.15K at STP

Replacing:

718torr*47.9mL / 299.15K = 760torr*V2 / 273.15K

41.3mL = V2
