At a temperature of 298 K, the Henry's law constant is 0.00130 M/atm for oxygen. The solubility of oxygen in water 1.00 atm would be calculated as follows:
<span>S = (H) (Pgas) = 0.00130 M / atm x 0.21 atm = 0.000273 M
</span>
At 0.890 atm,
<span>S = (H)(Pgas) = 0.00130 M / atm x 0.1869 atm = 0.00024297 M</span>
<span>
If atmospheric pressure would suddenly change from 1.00 atm to 0.890 atm at the same temperature, the amount of oxygen that will be released from 3.30 L of water in an unsealed container would be as follows</span>
<span>
3.30 L x (0.000273 mol / L) = 0.0012012 mol</span>
3.30 L x (0.00024297 mol / L) = 0.001069068 mol
0.0012012 mol - 0.001069068 mol = 0.000132 mol
Lol i think i had the same worksheet!! lol anyway look up newtons first law and it will be pretty self explanatory from there
Answer:
Retina is the part of eye which is used to see things in high details
The height function would be s(t) = -16t^2 + 64t + 32.
Maximum height ---> set s'(t) = 0.
-32t + 64 = 0. ---> t = 2. s(2) = -16(2)^2 + 64(2) + 32 = the maximum height is 96 feet.
To find the velocity when it hits the ground, set s(t) = 0.
-16t^2 + 64t + 32 = 0. Divide by -16.
t^2 - 4t - 2 = 0. The only positive solution is x = 4.45.
s'(4.45) = -32(4.45) + 64 = It's going -78.4 feet/second when it hits the ground.
