Answer:
Ppm <u>means the concentration of vapors or gases</u> expressed in parts per million of polluted air.
Explanation:
In Chemistry and Physics, part per million or PPM is a measure that expresses the number of units of a certain existing substance for every million units of the mixture. (Concentration)
In climate the equation is used so:
- ppm = parts of polluted air / million parts of air
.
- ppm = Liters of polluted air / 10∧6 Liters of air.
This is used to find the concentration of gases expressed as parts of gas per million parts of the
polluted air.
In this case, it would be<u> 407.4L of CO2 per 10∧6L of air.</u>
The statement of the combined gas law for a fixed amount of gas is,
PV/T = constant
Here, the units of pressure and volume must be consistent and the temperature must be the absolute temperature (Kelvin or Rankine).
0.65 atm is equivalent to 494 mmHg
Using the equation:
(755 x 500) / (27 + 273) = (494 x V) / (-33 + 273)
V = 3396 ml = 3.4 liters
Answer:
Option B. At pH extremes, the amino acid molecules mostly carry a net charge, thus increasing their solubility in polar solvent.
C. At very low or very high pH, the amino acid molecules have increased charge, thus form more salt bonds with water solvent molecules.
Explanation:
Answer:
Explanation:
Temperature and thermal energy are in a direct proportion which means that if temperature of a substance increases, its thermal energy also increases and vice versa.
