The best way to separate out a precipitate is using vacuum filtration. Use water to rinse out the flask thoroughly and wash the precipitate, followed by a quick rinse with ethanol to help dry it. After a few minutes on the vacuum pump, the precipitate should be ready to scrape off.<span> Also, centrifugation can be an option for small amounts especially if you just need the filtrate. For reasonable amounts, a Millipore setup or Gooch type crucible works nicely for quantitative analysis.</span>
Answer: 0.0624 atm
Explanation:-
According to the ideal gas equation:
P = Pressure of the gas = ?
V= Volume of the gas = 45.0 L
T= Temperature of the gas = -10.0°C = 263 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
Moles of gas=
The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm

<h3><u>Answer;</u></h3>
10 percent
<h3><u>Explanation;</u></h3>
- Probability is a number that describes how likely it is that an event will occur.
- In this case; If each of 10 events is equally likely to occur, the probability of each individual event occurring is 1/10.
- Therefore; as a percentage;
1/10 × 100 = 10 percent
- Hence; The probability of each individual event occurring is 10 percent
