Answer:
Possible lowest volume = 0.19 cm
Possible highest volume = 0.21 cm
Explanation:
Given Data
uncertainty = 0.01 cm
total volume = 0.20 cm
Possible lowest volume = ?
Possible highest volume = ?
Solution:
Possible lowest volume = total volume - uncertainty
Possible lowest volume = 0.20 cm - 0.01 cm
Possible lowest volume = 0.19 cm
Possible highest volume = total volume + uncertainty
Possible highest volume = 0.20 cm - 0.01 cm
Possible highest volume = 0.21 cm
So for the first one It's 784.56 J (GPE)
For the second one it's KE is equal to 100 J. If you can give me a few more minutes I'll try to get the GPE
Answer:
The concentration is 6.42×10^-4 M
Explanation:
Number of moles trichloroethylene = pressure × volume/Henry's constant = 0.00301×0.21/0.00985 = 0.0642 mol
Volume of mixture = 100 L
Concentration of trichloroethylene = number of moles of trichloroethylene/volume of solution = 0.0642/100 = 6.42×10^-4 M
the answer is none
Explanation:
Water
Water is the most polar molecule because a bond between oxygen and hydrogen has the most difference out of the atoms listed. Although the oxygen has two hydrogens bonded, this does not decrease the electronegativity of oxygen, but oxygen unfairly shares sets of electrons from both hydrogens, making it more polar still
Answer:
1121.08 millilitres of 0.223 M 
solution contains 0.250 moles of .
Explanation:
The formula for molarity of a solution:
Molarity = 0.223 M
n = 0.250 moles
Therefore, 1121.08 millilitres of 0.223 M solution contains 0.250 moles of .
