If 34.5 mol of an ideal gas occupies 11.5 L at 31.00 ∘C, what is the pressure of the gas?
Calculate the mass of Kr in a 4.59 L cylinder at 34.2 ∘C and 3.28 bar .
The ideal gas law relates the amount of gas present to its pressure, volume, and temperature. The ideal gas law is typically written as
𝑃𝑉=𝑛𝑅𝑇
where 𝑃 is the pressure, 𝑉 is the volume, 𝑛 is the number of moles of gas, 𝑅 is the ideal gas constant, and 𝑇 is the temperature.
Rearrange the equation to solve for 𝑃.
What is the pressure of 0.293 moles of an ideal gas at a temperature of 298.0 K and a volume of 4.62 L?
Suppose we observe that the equilibrium price of a particular good has decreased significantly over the past 5 years, with virtually no change in the equilibrium quantity. Which of the following is the most likely explanation? Over the past 5 years:
A. both supply and demand have decreased.
B. supply has increased but demand has decreased
C. both supply and demand have increased
D. demand has increased but supply has decreased.
Draw the structure of the tripeptide, which is composed of Phe+Lys+Cys and answer additional questions .
1.1. specify the value of the isoelectric point
1.2 select the indicator and determine the pH of the aqueous solution by indicator's color 1.3 specify the hydrophilic-hydrophobic balance
1.4 draw the structures of the tripeptide that correspond to the pH values 0, pl, 7, 14. Specify the charge of the tripeptide in each pH
2. Construct the Fişcher's formula for the D-mannose [2(L),3(L),4(D),5(D),6- pentahydroxyhexan-1-al] and draw all the tautomers: oxo, and pyranoses, furanoses. 3.Give the formula of the nucleic base cytosine, nucleoside cytidine, nucleotide cytidine-3-phosphate
A friendly letter of an incident /event that has enabled me to gain powerful insights into how to relate to people around me .This has led me to soul searching on my part
which animal has scales on the lower part of the legs and on the feet
Robin Hood stole from the rich and gave to the poor. There were only a small number of rich people. The majority of the people were poor. Taking from the rich, made the rich people sad but it made the poor people happy. If I say that Robin Hood was a hero, which ethical theory would I be following?

Robin Hood stole from the rich and gave to the poor. There were only a small number of rich people. The majority of the people were poor. Taking from the rich, made the rich people sad but it made the poor people happy. If Robin Hood had dangerous work BUT he never took unnecessary risks and his actions were always balanced. If he was acting out of caring and kindness. If those he stole from were tyrants and by taking away from them he was lessening the oppression of the people. If he believed that it was most important to cultivate good character. Which ethical theory could he possibly be following?
