There are 1224 grams in 6.8 moles of C6H12O6
From Graham's law of diffusion the effusion rate of a gas is inversely proportional to the square root of its molar mass.
Therefore for helium and radon; Helium has a mass of 4 g while randon has 222, hence;
= √222/√4
= 14.90/2
= 7.45
Thus the ratio of effusion rate between helium and randon is 7.45
Answer:
high
Explanation:
because of the strong crystal structure mentioned in the question, ionic compounds require a higher level of heat to melt
The community with high blood varsity is represented with species richness
<h3>What is a community with high biodiversity?</h3>
A community with high biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
The number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.
