This is one of the ideal gas laws. Presumably the pressure remains the same so it is not part of the givens.
Formula
V / T = V1 / T1
Givens
- V = 56.05 mL
- T = 315.1 degrees Kelvin
- V1 = x
- T1 = 380.5 degrees Kelvin
Solution
56.05/315.1 = x/380.5 Simplify the left.
0.1779 = x / 380.5 Multiply both sides by 380.5
0.1779 * 380.5 = 380.5x/380.5
67.68 mL = x This is your answer
No of moles of fe2o3 = 16.5/(55.8x2+16x3)=0.103mols
No. Of moles of iron= 0.103 x 2 = 0.206mols
Mass of iron = 0.206 x 55.8 = 11.5g
The answer would be km in 5 seconds
Answer:
Resting potential
Explanation:
The resting potential is the term used to the describe the difference in electrical charge across a membrane. Ion is solution are capable of carrying a charge so their presence in biological systems is of interest. Two factors affect the resting potential:
- the concentration gradients of the ions in solution across the membrane
- the permeability of the said membrane to the ions mentioned above
Molecules of salt, atoms, chocolate cake, cells, magnets
