The answer would be D. Bohrs model.
This problem is providing us with the mass of sulfur dioxide and the molecules contained are required. At the end, the result turns out to be 3.252x10²³ molecules, according to:
<h3>Avogadro's number:</h3>
In chemistry, we use the Avogadro's number in order to successfully perform mole-mass-particles calculations. Defined as 6.022x10²³, it provides the number of atoms, molecules and ions in one mole of the substance.
In this case, in order to obtain the result, one first calculates the moles in 34.61 grams of sulfur dioxide and then utilize the Avogadro's number to obtain the number of molecules as shown below:

1 mole of H2O weighs 18 g
therefore 13.8 g of liquid H2O = 13.8/18 moles
ΔHvaporization = 40.65 kJ/mol
heat required to change 13.8 grams of H2O from a liquid to a gas at 100 degrees Celsius = 40.65 x 13.8/18 = 31.165 kJ
The answer is large leaves.
These enable the plant to absorb more of the scarce sunlight it receives, so it can create enough nutrients for it to survive.
