Explanation:
population of geese = 1000
number of males in first year = 400 = (400/1000)x100 = 40%
number of males in second year = 500 = (500/1000)x100 = 50%
10% more of the male population is compared with one year ago.
There is a couple different ways to determine if<span> a </span>bond<span> is </span>ionic or covalent<span>. By definition, an </span>ionic bond<span> is between a metal and a nonmetal, and a </span>covalent bond<span> is between 2 nonmetals. So you usually just look at the periodic table and </span>determine whether<span> your compound is made of a metal/nonmetal or is just 2 nonmetals</span>
Answer:
27 g
Explanation:
M(C6H12O6) = 6*12 + 12*1 + 6*16 = 180 g/mol
100 mL = 0.1 L solution
1.5 M = 1.5 mol/L
1.5 mol/L * 0.1 L = 0.15 mol C6H12O6
0.15 mol * 180 g/1 mol = 27 g C6H12O6
<span>the one that is considered a chemcial mutagen is : Tobacco
Chemical mutagen refer to the substance that affected the DNA of those who consume the substancce or their offspring.
Studies showed that consuming tobacco has proven to created DNA deformations for the fetus if it consumed by pregnant women</span>
Correct answer is 
.
Phosphoric acid is a polyprotic acid having 3 acidic hyrdogen therefore it will have 3 pka values.
The equations for the release of acidic hydrogen can be written as:
From the pka values we can judge the idea of pH as using Henderson-Hasselbalch Equation, we get the relation between pH and pka.
Using the following equation, relation of pH and pka is
![pH=pka+log\frac{[A^-]}{HA}](https://tex.z-dn.net/?f=pH%3Dpka%2Blog%5Cfrac%7B%5BA%5E-%5D%7D%7BHA%7D)
Using this equation, we can find that the equation having pka= 2. 14 is closest to the pH=3.2 so the ionic form in this equation will be dominant at the same pH.
Therefore at pH=3.2 the ionic form of 
is dominant.
