Answer: CO is a limiting reagent with regards to the Fe production.

Explanation:

Fe_2O_3(s)+3CO(g)\rightarrow 2Fe(s)+3CO_2(g)

Moles of CO = \frac{\text{mass of CO}}{\text{molar mass of CO}}=\frac{13.2 g}{28 g/mol}=0.4714 mol

moles of Fe_2O_3=\frac{\text{mass of} Fe_2O_3}{\text{molar mass of}Fe_2O_3}=\frac{42.7 g g}{159.7 g/mol}=0.2673 mol

According to reaction , 3 mole of CO reacts with 1 mole of Fe_2O_3 then , 0.4714 moles of CO will react with : \frac{1}{3}\times 0.4714 moles of Fe_2O_3 that is 0.1571 moles.

0.4714 moles of CO will react with 0.1571 moles of Fe_2O_3 which means that CO is present in limited amount acting as limiting reagent.

Mole remaining of Fe_2O_3 = 0.2673 mol - 0.1571 mol = 0.1102 mol

Hence, CO is a limiting reagent and  Fe_2O_3 is an excessive reagent.

Rom4ik [11]

Answer:

Use the activity formula,  

T1/2 = 4.468 x 10^9 yr x 365 x 24 x 3600 = 1.409 x 10^17 sec  

l = ln(2)/T1/2 = ln(2)/1.409 x 10^17 = 4.91932697 x 10^-18 s-1  

DN/Dt = lN, 265 = 4.91932697 x 10^-18 x N  

<u><em>N = 5.38 x 10^19 nuclei</em></u>

Products: 1-methylcyclohexene, 3-methylcyclohexene, methylenecyclohexane
Lostsunrise [7]

Answer:

See explanation

Explanation:

The reaction that we are considering here is quite a knotty reaction. It is difficult to decide if the mechanism is actually E1 or E2 since both are equally probable based on the mass of scientific evidence regarding this reaction. However, we can easily assume that the methylenecyclohexane was formed by an E1 mechanism.

Looking at the products, one could convincingly assert that the reaction leading to the formation of the two main products proceeds via an E1 mechanism with the formation of a carbocation intermediate as has been shown in mechanism attached to this answer. Possible rearrangement of the carbocation yields the 3-methylcyclohexene product.

Using Models to Answer Questions About Systems
viva [34]
1A: The legs can be a adjusted, as well as the sand can be swapped out. It’s a very good design for running multiple tests.
1B: He could add books or something under the front or back legs in order to increase/decrease the incline, therefore imitating the hypothesis.
1C: He can change out the sand grains to finer ones, or coarser ones, and record his results of each test.
2: If he sets the model at a steep incline and tests it with coarse sand and fine sand, seeing which one makes a narrower, deeper hole.

How many molecules of BH3 are in 14.32 grams of BH3?
kkurt [141]

Answer:

6.23 x 10^23 molecules

Explanation:

First find the number of moles of BH3 from the information given. We know the amount of grams present and we can find the molar mass which is 13.84.

We know that moles is grams divided by molar mass so we get 14.32/13.84 which is 1.03 moles.

Finally, to figure out the number of molecules, we multiply 1.03 by Avogadro's number which is 6.022x10^23 and we get 6.23x10^23 molecules.

8.) If 396 g of Carbon Dioxide (CO2) are produced, what mass of Oxygen<br> (02) reacted? *
Brut [27]

Answer:

264g

Explanation:

C + O2 -> CO2

_g + _g -> 396g

396÷3=132

C (132g) + O2 (264g) -> CO2 (396g)
