Why Walden's rule not applicable to small size cations?
Walden's rule states that ions of similar size have similar properties. However, for small cations, the high charge density can lead to significant interactions with surrounding molecules, causing deviations from Walden's rule. These interactions can affect properties such as solubility and reactivity, making the rule less applicable for small cations.
How many significant figures are in 9.090?
If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.
A student calculates the density of an unknown solid The mass is 10.04 grams and the volume is 8.21 cubic centimeters How many significant figures should appear in the final answer?
The final answer should have three significant figures as dictated by the measurements provided (10.04 grams and 8.21 cubic centimeters). The result of the calculation cannot have more significant figures than the least precise measurement.
How does the 10 percent rule apply to the food chain?
The 10 percent rule in ecology states that only about 10% of energy is transferred from one trophic level to the next in a food chain. This is because energy is lost as heat during metabolic processes, limiting the amount of energy available for organisms at higher trophic levels. Consequently, this rule helps to explain why food chains are typically limited in length.
