Answer:
The routes are in the attached figure bellow.
Explanation:
In order to have a nucleophilic substituition, we need a substract with a positive or partially positive carbon. Therefore, the two possible substracts chosen were alkyl halides. The chlorine is more electronegative than the carbon, therefore the electronic density will be deslocated towards the Cl atom an the C atom will be left partially positive.
The nucleophiles given have strong negative charges and will attack the partially positive carbon. The chlorine will then leave the molecule (leaving group) and a new bond between the carbon and the oxigen will be formed.
Both routes will involve a Sn2 mechanism, which means that the reactions will occur in one step.
Answer:
19.32
Explanation:
the density is given by the mass over volume
the mass In this case is 342.93 and the volume is 17.75
d=342.93g/17.75cm
=19.32g/cm
i hope this helps
In sodium carbonate I believe the carbonate is considered the base and that the HCl will react with the carbonate to produce bicarbonate (HCO₃). Due to that, I think the chemical equation should be HCl+NaCO₃→HCO₃+NaCl.
To neutralize the solution, you need to have equal amounts H⁺ and CO₃⁻ which means that you need to have equal amounts HCl and NaCO₃. To find this you need to know how many moles of NaCO₃ there are in the 25mL solution since that is the number of moles of HCl you need. You would then divide the number of moles of HCl needed by 2M to find the volume of HCl needed.
With the information given I don't think you can answer this. You need to know what the concentration of the sodium carbonate is and with out that value you can't determine how many moles of sodium carbonate there are. You need to know how many moles of sodium carbonate you have in order to know how much 2M hydrochloric acid is needed to neutralize it.
The process you would usually use is:
(0.025L NaCO₃)×(molarity of NaCO₃)=moles NaCO₃
moles NaCO₃=moles HCl needed to neutralize
(moles HCl needed to neutralize)/2M=Liters of HCl needed to neutralize
Let me know if the question came with any more information but right now I don't think it can be solved.
I hope this helps. Let me know if anything is unclear.
Also, since this reaction is between a strong acid and weak base, when you neutralize it with the strong acid the pH of the solution will not be 7. It will most likely be under seven since HCO₃ is being produced which is the conjugate acid of CO₃ and therefore create a slightly acidic solution at the equivalence point (the equivalence point is another way of saying the solution was neutralized). You probably don't need to know this for the scope of your class but I thought it was worth mentioning since later on you will have to deal with this fact.
Ionic compounds are compounds that are composed of oppositely charged ions, anions and cations. The force which holds the two ions (charged atoms) together is called the electrostatic force, and the bond that exists between them is called an ionic bond.
An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and non metals, gaining electrons.
Monoatomic elements are elements that are stable as single atoms. The chemical elements which are stable single-atom molecules at standard temperature and pressure (STP) are noble gases. These are helium, neon, argon, krypton, xenon, and radon.
Ionic compounds are made up of oppositely charged ions which are held together by strong electrostatic force of attraction. Due to this reason, they are hard solids.
