To determine the limiting reactant, we divide the number of moles to its corresponding stoichiometric coefficient. Balancing the equation above, we get 4 Li + O2 = 2Li2O. For lithium, the result is 2.1 and for oxygen, the result is 4.6. The limiting reactant has the smaller ratio. So, the limitin reactant is lithium.

Answer: Lithium

Explanation: The balanced chemical equation is:

4Li+O_2\rightarrow 2Li_2O

It can be seen, 4 moles of lithium combines with 1 mole of oxygen gas to produce 2 moles of lithium oxide.

Thus 8.4 moles of lithium combines with=\frac{1}{4}\times {8.4}=2.1molesof oxygen gas to produce 4.2 moles of lithium oxide.

As, Lithium limits the formation of product, it is the limiting reagent and Oxygen gas is present in excess, it is called the excess reagent. (4.6-2.1)=2.5 moles of oxygen gas are present in excess.

Nitrogen reacts with hydrogen to produce ammonia gas as follows. mc023-1.jpg How many moles of nitrogen would react with excess
anzhelika [568]
The balanced reaction is:

N2 + 3H2 = 2NH3

We are given the amount of the product to be produced.This will be the starting point of our calculations. We use the ideal gas equation to find for the number of moles.

<span>
n = PV / RT = 1.00(.520 L) / (0.08206 atm L/mol K ) 273 K
n= 0.0232 mol NH3

</span>0.0232 mol NH3 (1 mol N2 / 2 mol NH3) = 0.0116 mol N2


<span>Therefore, the correct answer is A.</span>

Explain why you would want to keep some, but not all, receipts as part of your financial records.
miss Akunina [59]

Answer:

Explanation:

Let's try and figure out the ones you don't keep.

Receipts from the dollar tree. You can't return what you bought and you only paid a dollar. It's not worth it.

Food receipts. You can't return it and unless you want to itemize what you spend / month and on what, they don't serve any purpose.

Now figure out which ones you would want to keep

1. Anything pertaining to medical perscriptions. I don't know how it works in the United States, but in Canada we are allowed to deduct only medications with a DIN number.

2 Anything that you would use for travelling that is not for pleasure (ie it is a business expense). So if you are a salesman and your territory is from A to B you would deduct meals, mileages, motels if you must stay away from home

3 In the states some tax receipts are deductible, so you might want to save those.

Choose the appropriate electron configuration for an element whose third shell contains six electrons.​
slamgirl [31]

For an element whose third shell contains six electrons, the appropriate electron configuration is; 1s2 2s2 2p6 3s2 3p4.

The electron configuration shows the distribution of electrons in the shells of an atom and in orbitals.

We have been told that the six electrons are found in the third shell. This shell has n=3 and the configuration of this shell must ns2 np4.

The only electron configuration that meets this standard is 1s2 2s2 2p6 3s2 3p4.
