Answer:
c
Explanation:
because of over-hunting, poaching, pollution, loss of habitat, the arrival of invasive species, and other human-caused problems
57 degrees celcius is equal to 330 degrees kelvin
67.88 kPa is equal to 67880 Pa
85.3 liters is equal to 0.0853 m^3
Now, the equation we will use to solve this question is:
PV = nRT where:
P is the pressure of gas = 67880 Pa
V is the volume of gas = 0.0853 m^3
n is the number of moles we are looking for
R is the gas constant = 8.31441 J K-1<span> mol</span><span>-1
T is the temperature of gas = 330 degrees kelvin
Substitute with the givens in the above equation to get n as follows:
n = (PV) / (RT)
n = (67880*0.0853) / (8.31441*330)
n = 2.11 moles</span>
C is incorrect. I has 21 PROTONS in its nucleus. Not neutrons.
The answer is D because the box b's force to the left is not being cancelled out and box d's force is trying to be cancelled out, but he has more force going up then down so he is moving up
