106.4 is going to be your answer
Answer:
0
Explanation:
There are no unpaired electrons in the given element. It must be noted that for the atom above, we have even numbered electrons. The total electron we are having here is 18.
Now, we must also know that while the s orbital is not degenerate, the P orbital is degenerate. What this mean is that the p orbital is broken down into three different sub orbitals which is the Px , Py and Pz. Hence we can see that there are 6 electrons to enter into the P orbital too.
We can see that all the S orbitals have been completely filled with two electrons alike each. This is also the case for the P orbital as the 3 suborbitals take in 2 each to give a total of six
Answer:
23.9g of Fe₂O₃ are produced
Explanation:
<em>Are formed when 16.7g of Fe reacts completely...</em>
<em />
Based on the reaction:
4Fe + O₃ → 2Fe₂O₃
<em>4 moles of Iron react per 1 mole of O₃ producing 2 moles of Fe₂O₃.</em>
<em />
To solve this question we need to convert the mass of iron to moles. The ratio of reaction is 2:1 -That is, 2 moles of Fe produce 1 mole of Fe₂O₃-. Thus, we can find the moles of Fe₂O₃ produced and its mass:
<em>Moles Fe -Molar mass: 55.845g/mol-:</em>
16.7g Fe * (1mol / 55.845g) = 0.299 moles of Fe
<em>Moles Fe₂O₃:</em>
0.299 moles Fe * (2 mol Fe₂O₃ / 4 mol Fe) = 0.150 moles Fe₂O₃
<em>Mass Fe₂O₃ -Molar mass 159.69g/mol-:</em>
0.150 moles Fe₂O₃ * (159.69g / mol) =
<h3>23.9g of Fe₂O₃ are produced</h3>
<em />
It had a more immediate effect because it enters directly into the blood stream.
The answer is (1) the reaction is exothermic because it releases heat. From the reaction, we can see that the heat is at the right of the equation which means the reaction releases heat. So it is called exothermic reaction. Endothermic reaction absorbs heat.
