Answer:
B
Explanation:
the fluorine has an high tendency to gain electrons from other elements with lower electronegativities
69 mmHg pressure is exerted by oxygen if 40% of the gas pressure is exerted by the oxygen gas.
<h3>What is pressure?</h3>
Pressure is defined to be the amount of force exerted per area
40% of pressure is exerted by oxygen gas.
So, 60% of pressure will be exerted by carbon dioxide gas.
60% of 115 mmHg = 69 mmHg
Hence, 69 mmHg pressure is exerted by oxygen if 40% of the gas pressure is exerted by the oxygen gas.

The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.
Mathematically;
The dilution factor is given by the formula;
Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution
Final volume of the now diluted solution = 100.0 ml
Initial volume of more concentrated solution = 10.00 ml
Dilution factor = 100.0 ml/10.00 ml
Dilution factor = 10
