Answer:
23 kPa = Partial pressure O₂
Explanation:
In a mixture of gases, the sum of partial pressure of each gas that contains the mixture = Total pressure
Total pressure = Partial pressure N₂ + Partial pressure CO₂ + Partial pressure O₂
95 kPa = 48 kPa + 24 kPa + Partial pressure O₂
95 kPa - 48 kPa - 24 kPa = Partial pressure O₂
23 kPa = Partial pressure O₂
The particles are given more energy and start to vibrate faster. In certain temps the particles vibrate so much that their ordered structure breaks down to the point the solid melts into liquid
Red shift is one piece of observational evidence which supports the big bang theory. The fact that galaxies are moving away from us means that the universe was once much smaller, supporting the big bang theory which states that all the matter in the universe once occupied a single point with infinite density.
Hey there!
2.70 moles of Fe x (6.022 x 10^23) atoms of Fe = 1.63 x 10^24 atoms of Fe
_______________________
1 mole of Fe
Answer: 1.63 x 10^24 atoms of Fe
Hope this helps :)
Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.
the mass of glucose is - 125 g
number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol
the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol
number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L
molarity of glucose solution is 1.068 M
