Since its asking for just the reactant, you can ignore the whole left side. Now since its only asking for the reactant containing Nitrogen, you can ignore the NaHCO3 since it doesnt have nitrogen.
That leaves us with drawing the structure of NH4Cl.
This was a tough one for me to find, as I kept drawing Ammonia instead and couldnt figure out how to fit in the extra Hydrogen and Chlorine. Luckily, this Y!A answer explains it, its due to a hydrogen bond
Answer:
648.68 mg
Explanation:
The reaction that takes place is:
- FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
First we<u> calculate how many moles of each reactant were added</u>, using the <em>given volumes and concentrations</em>:
- FeCl₃ ⇒ 100 mL * 0.240 M = 24 mmol FeCl₃
- NaOH ⇒ 100 mL * 0.182 M = 18.2 mmol NaOH
24 mmol of FeCl₃ would react completely with (24 * 3) 72 mmol of NaOH. There are not as many NaOH mmoles, so NaOH is the limiting reactant.
Now we <u>calculate how many moles of Fe(OH)₃ are formed</u>, using the <em>moles of the limiting reactant</em>:
- 18.2 mmol NaOH * = 6.07 mmol Fe(OH)₃
Finally we <u>convert 6.07 mmol Fe(OH)₃ to grams</u>, using its<em> molar mass</em>:
- 6.07 mmol Fe(OH)₃ * 106.867 mg/mmol = 648.68 mg
The answer is; They each have the same number of protons
All uranium isotopes have 92 protons in their nucleus. However, they differ in the number of neutrons in the nucleus, hence this also translates to varying mass numbers (which is the sum of neutrons and protons in the nucleus). The most common isotopes of uranium are; U-238, U-235, and U-234.
It is easier to predict the boiling point of heptene rather than its melting point because of their geometrical isomerism.
<h3>What is melting point?</h3>
Melting point is that point at which any compound changes its state from solid to another state liquid, and at this point both the states are present in equilibrium.
It is easier to predict the boiling point of heptene as in this molecule constant number of double bond is present its not changing. But due to double bond heptance shows cis and trans isomer, and among them one isomer will be stable and another one is unstable.
That's why it is not easy to predict the melting point.
Hence, due to geometrical isomers it is not easy to predict melting point.
