If Wave speed=wavelength*frequency, this means that it can be flipped around. I hope this helps.
The least prevalent gas in the atmosphere was oxygen several billion years ago. This is because it was only around 2.4-3 billion years ago when the first photosynthetic bacteria evolved, meaning they produce food from inorganic compounds such as carbon dioxide and water to produce glucose and oxygen. Oxygen is then released in the atmosphere and this is called <em>The Great Oxygenation Event</em>.
Answer:
n = 2 moles (1 sig-fig)
Explanation:
Using the Ideal Gas Law equation (PV = nRT), solve for n (= moles) and substitute data for ...
pressure = P(atm) = 100atm
volume =V(liters) = 50L
gas constant = R = 0.08206L·atm/mol·K
temperature = T(Kelvin) = °C + 273 = (35 + 273)K = 308K
PV = nRT => n = PV/RT = (100atm)(50L)/(0.08206L·atm/mol·K)(308K)
∴ n(moles) = 1.978moles ≅ 2 moles gas (1 sig-fig) per volume data (= 50L) that has only 1 sig-fig. (Rule => for multiplication & division computations round final answer to the measured data having the least number of sig-figs).
Answer: The isotopic abundance of Cl- 37 is 0.2424.
Explanation:
Mass of isotope - 35 = 34.96885 amu
% abundance of isotope -35= x% =
Mass of isotope - 37 = 36.9659 amu.
% abundance of isotope-37 = (100-x)% =
Formula used for average atomic mass of an element :
Therefore, the isotopic abundance of Cl- 37 is 0.2424.
