Answer:
It is significant that so much carbon dioxide stays in the atmosphere because, CO2 is the most important gas for controlling Earth's temperature. //Plants breathe in CO2 to give us oxygen.
Answer:
The molar mass = 39.4 g/mol
Explanation:
The given parameters are;
The pressure at which the gas was measured = 1.3 atm.
The temperature of the gas = 47°C
The measured density of the gas = 1.95 g/L
By the combined gas equation, we have;
![P \cdot V = n \cdot R \cdot T](https://tex.z-dn.net/?f=P%20%5Ccdot%20V%20%3D%20n%20%5Ccdot%20R%20%5Ccdot%20T)
Where;
n = Number of moles = m/MM
P = Pressure = 1.3 atm
V = Specific, Molar Volume
T = Temperature = 47 °C = 320.15 K
R = Universal Gas Constant = 0.08205 L·atm/(mol·K)
ρ = The density = MM/V
Where;
MM = Molar mass
Therefore, V = MM×ρ
![V/m= \dfrac{1/(MM) \cdot R \cdot T}{P}](https://tex.z-dn.net/?f=V%2Fm%3D%20%5Cdfrac%7B1%2F%28MM%29%20%5Ccdot%20R%20%5Ccdot%20T%7D%7BP%7D)
![\rho= \dfrac{1/(MM) \cdot R \cdot T}{P}](https://tex.z-dn.net/?f=%5Crho%3D%20%5Cdfrac%7B1%2F%28MM%29%20%5Ccdot%20R%20%5Ccdot%20T%7D%7BP%7D)
![MM = \dfrac{\rho \cdot R \cdot T}{P} =\dfrac{ 1.95 \times 0.08205 \times 320.15} {1.3} = 39.4 \ g/mol](https://tex.z-dn.net/?f=MM%20%3D%20%5Cdfrac%7B%5Crho%20%5Ccdot%20R%20%5Ccdot%20T%7D%7BP%7D%20%3D%5Cdfrac%7B%201.95%20%5Ctimes%200.08205%20%5Ctimes%20320.15%7D%20%7B1.3%7D%20%3D%2039.4%20%5C%20g%2Fmol)
Disorders are classified in a mult “dimensional” manner, not to mention the difference between a human and its disorders.
Man-to-man defense means that you have your assigned opposing player that you're supposed to guard and you run around following him and guarding him. In zone defense, you guard an area of the court, not the man, so you're not supposed to let anyone stay there. In the NBA, zone is forbidden because it slows down the game, making it more boring for fans, so they've developed a special type of a defense where they rotate all the time while still keeping some aspects of the zone.
