This is more a biology question but anyway....
G = the dominant gene aka. the one that is most likely to be seen because it is stronger than g. GG and Gg will both show the dominant gene's characteristics.
g = the recessive gene. The only way this one's type can be seen in gg form with no dominant gene to overpower it
To convert a number without the use of the expression 10^-4 you would have to treat it like an integer line for instance on an integer line the negative is to the left and the positive number is to the right so 3.91*10^-4 means that the decimal would have to move 4 places to the left so the answer would be .000391 instead of 3.91*10^-4.
I hope this helps you :)
Answer:
4.82 g
Explanation:
To solve this problem we'll use the <em>definition of molarity</em>:
- Molarity = moles / liters
We are given the volume and concentration (keep in mind that 100mL=0.100L):
- 0.825 M = moles / 0.100 L
Now we <u>calculate the number of NaCl moles required</u>:
Then we convert 0.0825 NaCl moles into grams, using its molar mass:
- 0.0825 mol * 58.44 g/mol = 4.82 g
Answer:
pH = 10.11
Explanation:
Hello there!
In this case, since it is possible to realize that this base is able to acquire one hydrogen atom from the water:
We can therefore set up the corresponding equilibrium expression:
![Kb=\frac{[C_{18}H_{21}NO_4H^+][OH^-]}{[C_{18}H_{21}NO_4]}](https://tex.z-dn.net/?f=Kb%3D%5Cfrac%7B%5BC_%7B18%7DH_%7B21%7DNO_4H%5E%2B%5D%5BOH%5E-%5D%7D%7B%5BC_%7B18%7DH_%7B21%7DNO_4%5D%7D)
Which can be written in terms of the reaction extent, 
:
Thus, by solving for we obtain:
However, since negative solutions are now allowed, we infer the correct is 0.0001285 M; thus, the pOH can be computed:
And finally the pH:
