The fraction recrystallized-time data for the recrystallization at 350°C of a previously deformed aluminum are tabulated here. Assuming that the kinetics of this process obey the Avrami relationship, determine the fraction recrystallized after a total time of 116.8 min. Fraction Recrystallized 0.39 0.71 Time (min) 95.2 126.6

i need help solving this step by step with all the calculations  Below is a set of absorbance data that you have obtained while doing an experiment studying the diffusion of potassium permanganate into solutions of water. This diffusion experiment was conducted at three temperatures. I need help to Calculate the diffusion rates for each of these temperature conditions.  Time (min) 4°C 22°C 37°C 0 0.024 0.108 0.081 5 0.048 0.144 0.221 10 0.069 0.196 0.321 15 0.088 0.224 0.424 20 0.086 0.234 0.580 25 0.089 0.248 0.683 Once you calculate your diffusion rates  in standard notation and use 3 digits past the decimal point   (Note that the last zero is considered to be a digit)    Diffusion Rate 4°C =  __________________  Diffusion Rate 22°C = _________________  Diffusion Rate 37°C = _________________     To show how you calculated the diffusion rates for these temperature - What absorbance values did you choose to…

In chemistry class, a student conducted an investigation about factors affecting the solubility of copper (II) sulfate (CUSO4) in water. The data was recorded in the table below. Trial Factors Compound not stirred Temperature: 60ºC Large crystals Compound was stirred 2 Temperature: 25°C Large crystals Compound was not stirred 3 Temperature 25°C Large crystals Compound was stirred Temperature 60°C Finely crushed powder Which trial will have the slowest rate of dissolving? Explain the reasoning for your answer.

plz dont round and take your time. this one has been getting done wrong

A flask containing photosynthetic green algae and a control flask containing water with no algae are both placed under a bank of lights that is set to cycle between 12 hours of light and 12 hours of dark. The dissolved oxygen concentrations in both flasks are monitored. Predict what the relative dissolved oxygen concentrations will be in the flask with algae compared to the control flask. The dissolved oxygen in the flask with the algae will O always be lower be higher in the light but lower in the dark be higher in the light, but the same in the dark O always be higher

You are given three unknown samples stored in screw-cappedcontainers and was told to analyse them. You noted that Container A iscloudy and have some particles that are staying near the bottom of thecontainer. Container B is translucent while Container C is transparent. If thecontents of Container A can be separated by simple decantation,what isthe particle size that BEST describes its composition?i. <1 nmii. 1 nmiii. 1 nm-100 nmiv. >1000 nm

A silver-30%gold alloy sample (cylindrical with 1 cm diameter and 0.3 cm height) is subjected to a selective silver dissolution in 0.1 M HNO3 at current density of 2.5 mA/cm2 . How long will it take until the total amount of silver is dissolved? Assume in average a density of 12 g/cm3 for the alloy sample.

The Common App... An experiment was conducted using KNO3. The table below shows the data obtained after dissolving different masses of KNO3 in 10 ml of deionized water and then cooling to determine the temperature at which the different concentration of salts begin to recrystallize Concentration of KNO3 Saturation temperature(°C) 2g/10 ml 52.5 4g/10 ml 54.7 6g/10 ml 66.7 8g/10 ml 80.2 If a student dissolve 24g of KNO3 in 120 ml of deionized, at what temperature do you expect to see recrystallization O 52.5 degree celsius O 66.7 degree celsius 0:54.7degrce celsius O100.2 degree celsius
