Answer:
Wind direction is determined with a wind vane.
Hope it will help :)
We can calculate the amount of Oxygen in this volume using the Ideal Gas Equation, PV = nRT, where "P" is the pressure, "V" is the volume, "n" is the number of moles of material, "R" is the gas constant, and "T" is the temperature in Kelvin. To properly answer this problem, all of the information needs to be converted into the proper units. Fortunately, everything except the volume and temperature is in the correct units for the Ideal Gas Equation; the volume can be adjusted by converting mL to L (x1000) and the temperature can be adjusted by adding 273.15 to the current temperature (conversion from Celsius to Kelvin).
Plugging in all the values, we find that:
PV = nRT
(2.7 atm)(0.3 L) = n(0.0821*)(313.15 K)
n = 0.0315 mol Oxygen
Under these conditions, 0.0315 moles of oxygen can be placed in this volume.
Hope this helps!
* - the units are liters times atmospheres divided by moles times Kelvin.
This would be difficult to specify for you because you did not provide the genotype of the other parent. However, there are limitations to the possible combinations, so I will do each to help you out.
<u>1st possibility:</u>
<u>B B</u>
B BB BB
b Bb Bb
Brown eyes: 4 out of 4 or 100%
Blue eyes: 0 out of 4 or 0%.
<u>2nd possibility:</u>
<u>B b</u>
B BB Bb
b Bb bb
Brown eyes: 3 out of 4 or 75%
Blue eyes: 1 out of 4 or 25%.
<u>3rd possibility:</u>
<u>b b</u>
B Bb Bb
b bb bb
Brown eyes: 2 out of 4 or 50%
Blue eyes: 2 out of 4 or 50%.
<u>As long as there is a capital letter in the genotype, the dominant trait will come out. So if the combination is </u><u>Bb or BB</u><u>, then </u><u>BROWN </u><u>in this case will come out. The only time </u><u>BLUE eyes </u><u>will come out is if has two recessives in its genotype or </u><u>bb.</u>
Hi!
When Silver Oxide (Ag20) is heated, it decomposes into Silver and Oxygen.
