C. During a storm, a river is carrying a lot more sediment than during a low flow period
First, we must know that the hydronium ion is formed when a water molecule accepts a hydrogen ion. Therefore, the hydronium ion concentration is equivalent to the hydrogen ion concentration. Furthermore, the equation relating pH and hydrogen ion concentration is:
pH = -log[H+]
4.33 = -log[H+]
[H+] = 4.68 x 10⁻⁵ M
The concentration of hydronium ions is 4.68 x 10⁻⁵ M
Answer:
The plum pudding model would have to be true as well because it shows that electrons are scattered within an atom.
Explanation:
I took the test and got it right :)
The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is . Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
We are given:
Density of pentane =
Mass of pentane = 35.0 g
Putting values in above equation, we get:
(Conversion factor: )
Hence, the volume of pentane is 55.9 ml
