The solution for this problem is:
Let x = speed of wind
Speed of plane with the wind = x + 100
Speed of plane against the wind = 100 -x
We will be using the formula for distance which is (Rate)(Time), getting the formula for time would be distance/rate Time to travel 600 miles with the wind = Time to travel 400 miles against the wind 600/(x + 100) = 400/(100 - x)
400(x + 100) = 600(100 - x)
400x + 40000 = 60000 - 600x
1000x = 20000
x = 20000/1000
x = 20 mph
Answer:
0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.
Explanation:
The dose for treating Parkinson’s disease = 100 μg/kg body weight
Mass of patient's body = 70 kg
Amount of dose of deprenyl required = 100 μg/kg × 70 kg = 7,000 μg
1 μg = 0.00001 g
7,000 μg = 7,000 × 0.000001 g = 0.007 g
0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.
Answer:
You can determine x and y in the rate law by looking at experimental data and noticing how the change in concentration of a reactant is related to the reaction rate.

Let's eliminate some options.
Option A: quadruple bonds will most likely not occur between two carbon atoms. so option A is out.
Option B: One double bond with oxygen and two single bonds with hydrogen atoms will give all atoms the "noble gas" or "octet" configuration they desire. Option B is true.
Option C: Carbon is most likely not large enough to have more than eight valence electrons (hypervalent), so option C is out.
Option D: One carbon only has four valence electrons to donate, so the same problem exists as in option C, and the carbon atom will not achieve hypervalence. Option D is out.
Therefore, option B is correct.
