Answer:
51:49 is the ratio of female participants to male participants.
Explanation:
Percentage of females in the race = 51 %
Percentage of males in the race = 100% - 51 % = 49%
Total participants in race = 400
Number of women participants = 
Number of men participants = 
Ratio of female participants to male participants :
Answer:
8.2763 g
Explanation:
Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:
pH=pKa+log[base]/[acid]
Where Ka is the dissociation constant of the acid.
Given that the acid dissociation constant = 3.5×10⁻⁸
pKa = - log (Ka) = - log (3.5×10⁻⁸) = 7.46
Given concentration of acid = [acid] = 0.244 M
pH = 6.733
So,
6.733 = 7.46+log[base]/0.244
[Base] = 0.0457 M
Given that Volume = 2 L
So, Moles = Molarity × Volume
Moles = 0.0457 × 2 = 0.0914 moles
Molar mass of potassium hypochlorite = 90.55 g/mol
Mass = Moles × Molar mass = (0.0914 × 90.55) g = <u>8.2763 g</u>
The answer is prokaryote :)
Everything is deadly at a certain amount. Sometimes you accidently incest a small amount of something that's toxic, but it doesn't really do any harm because of how little it is. The body just gets rid of it during the its normal biological processes.
There's a certain amount of the toxin that you have to reach before the body begins to really feel it's effects and begin to get rid of it (vomiting, clamminess, all that jazz).
Of course it depends on the substance in question, some things are way more dangerous in much less amounts than others (e.g. ricin vs. poinsettia flowers).
Hope this helps!
