Answer:

Explanation:

A formal charge (FC) is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity(Wikipedia).

The formal charge on an atom in a molecule reflects the electron count associated with the atom compared to the isolated neutral atom(University of Calgary).

Looking at all the structures listed A-E for SeO2F2, only structure A minimizes the formal charges for each atom in SeO2F2.

How many moles of calcium chloride are contained in a 333 gram sample?

Bogdan [553]

Answer & Explanation:

The molar mass of calcium chloride is 110.98 g/mol. We can use this information to solve this problem. We can set up our equation like this..

$\frac{333 g(CaCl2)}{} *\frac{1mol(CaCl2)}{110.98g(CaCl2)}$

Multiply straight across on the top and straight across on the bottom.

$\frac{333}{110.98}$

Now divide.

$\frac{333}{110.98}=3.00$

So, there are 3.00 moles of calcium chloride contained in a 33 gram sample which is answer choice D.

Calculate the number of Carbon atoms in 1.50g of C6H12O6

Whitepunk [10]

Answer:

3.01 ·10↑22

Explanation:

First you want to convert the grams of Glucose to moles of Glucose.

$\frac{1.5 grams of glucose}{180.15588grams/molesglucose} =.008326 Moles of Glucose$

Next find the formula units of glucose.

.008326Moles of Glucose · 6.022 · 10↑23Forumula Units*Moles↑-1 =

5.01 ·10↑21 Formula Units of Glucose

Now multiply the formula units of glucose by the amount of each element in the molecule.

So for Carbon:

6carbon · 5.01 · 10↑21 = 3.01 · 10↑22

Explain haw fluctuations in abiotic can influence populations?

aleksandr82 [10.1K]

The fluctuations in abiotic cycles can influence the population in many ways. The population of a particular area depends on the various abiotic cycles such as nitrogen cycle, carbon cycle, phosphorous cycle. The changes in these cycles affects the life of population. Fluctuation results in hibernation of species. Some of the organisms migrate to another place in search of normal environment. The early breeding results in creating problems. It disturbs the ecological balance by using the limited supply of resources. The fluctuation in phosphorous cycle can affect the aquatic population. As the dependency of population on abiotic cycles is as important as the biotic factors the fluctuations can cause many problem.
