I would say that it's C. Seasonal temperatures have dipped over time, but I could easily be wrong, since it's my opinion. A weather condition is defined as the atmospheric conditions that 'comprise the state of the atmosphere in terms of temperature and wind and clouds and precipitation. But I believe it could just as easily be B. 150mm of rainfall is a normal average in the city.
In order to determine the mass of a substance given the volume, we require the density. The density of iron is 7.87 grams/cm³
Now,
Density = mass / volume
Mass = density * volume
Mass = 7.87 * 4.6
36.2 grams of iron are present in the cube
A catalyst will ALWAYS increase the reaction rate so C
With the principle quantum number being 2, the maximum number that can share this is 8. You can use the general formula 2n^2 to calculate this number (n=quantum level), or you can use the concept of quantum numbers (n, l, m, s) to justify this answer.
