Answer:
the real tricky one question
Explanation:
The number of the valence electrons determines the oxidation state i.e. oxidation number e.g. oxygen has 6 valence electrons the oxidation number is -2 that its need to fill up an octet structure.
Answer:
- <em>The measurements taken by </em><em><u>Jay</u></em><em> are least likely to contain random errors.</em>
Explanation:
All experimental measures are subject to errors.
Even when the colorimeter is properly calibrated and correctly used, there are random errors.
Random errors are are due to fortuitous factors, such as minor oversight by the observer or small changes of the conditions under which the measurements are made.
You can minimize the random errors by increasing the number of measurements, because the random errors tend to happen in any direction; some measures will be greater and other will be less than the true value.
Chance will make that errors in on direction cancel with errors in the opposed direction, making the average the best measure.
Thus, <em>Jay</em>, by <em>repeating the experiment five times and taking the average measurement</em>, is making that<em> his measurements are</em> <em>least likely to contain random errors.</em>
Answer:
P₂ = 592.7 torr
Explanation:
Given data:
Initial Pressure = 215 torr
Initial volume = 51.0 mL
Final pressure = ?
Final volume = 18.5 mL
Solution:
P₁V₁ = P₂V₂
P₁ = Initial Pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the values in formula.
P₁V₁ = P₂V₂
215 torr × 51.0 mL = P₂ × 18.5 mL
10965 mL. torr = P₂ × 18.5 mL
P₂ = 10965 mL. torr /18.5 mL
P₂ = 592.7 torr
