Answer: You would separate it by dissolving them.
Answer:
0.3152 M
Explanation:
The reaction that takes place is:
- 2MnO₄⁻ + 5C₂O₄⁻² + 16H⁺ → 2Mn⁺² + 8H₂O + 10CO₂
First we <u>calculate the MnO₄⁻ moles used up in the titration</u>, <em>by multiplying the volume times the concentration</em>:
- 21.93 mL * 0.1725 M = 3.783 mmol MnO₄⁻
Then we <u>convert MnO₄⁻ moles to C₂O₄⁻² moles</u>:
- 3.783 mmoles MnO₄⁻ *
= 9.457 mmol C₂O₄⁻²
Finally we <u>calculate the oxalate ion concentration</u>,<em> by dividing the moles by the volume</em>:
- 9.457 mmol C₂O₄⁻² / 30.00 mL = 0.3152 M
Answer:

Net ionic reaction for the solution containing equal concentrations of both HF(aq) and NaF(aq) is as follow:
F⁻(aq) + H₂O(l) ⇄ HF(aq) + OH⁻(aq)
Answer:
Yes, it is due to the gravitational pull from the moon
Explanation:
The mass of Garfield didn't change during the flight, which is to say, the amount of matter in his body is the same on Earth as on the Moon.
However, <em>weight is a measurement of how strongly mass is pulled towards the ground, due to the gravitational pull.</em>
So even though Garfield's mass is the same, the weight is less due to the lower gravitational pull from the Moon compared to Earth (the weight is one-sixth of the original weight as gravity on the moon is about one-sixth of Earth's). When Garfield returns to Earth, the scale will still read 24 lbs.
