Look at the files attached and let me know if you can solve these types of question. If you think you are confident with the material please bid on my project.
hi
i completed my PhD in chemistry.i am expert in chemistry.
i can help you with 100% accuracy within your time limit.
please contact me
I gone through all your questions. I can solve all the questions. I will deliver answers after 2 hours of bid granting.
thank you.
Hi,
I am a Mechanical Engineer with a first class honors degree. I can provide the answers for your chemistry problems accurately within the time you specify. You can check the reviews I got for my recent chemistry project and other projects to get an understanding of the quality of work that I maintain. Let me know the project particulars so that I can start working on it without further delay.
Regards
I am petrochemical engineer so this is very simple. I can solve for you! I am very confident with your project. If you agree, please send me an email to duccanh179@ gmail.com. I will give you solve after 1 day
I'll do the task with brief explanations. Now Exam1 is already (1-19 tasks).
For sample:
1. ...
Al(CH3COO)3
M(Al) + (M(C)*2+M(O)*2+M(H)*3)*3
26.98 + (12.01*2 + 16.00*2+3*1.01)*3 = 204.13
answer: E.
_______________________________________________________
12. ...
1 O2 + 2 H2
P(O)+ P(H) = P
1/2P(O) = P(H) = Px
1/2Px + Px = P
Px = P/1.5 = 741/1.5 = 494 mmHg (torr)
answer: E.
___________________________________________________________
18. ...
all atoms O on right = all at. O on left
for other atoms - too (N(P)left = N(P) Right for sample) => 2*P = 2*P; 3*Cl (FeCl3) = 3Cl (3NH4Cl)
3*NH4OH + 1*FeCl3 = 3NH4Cl + 1*Fe(OH)3
3*Na2CO3 + 2*H3PO4 = 2*Na3PO4 + 3*H2O + 3*CO2
2*C2H6 + 7*O2 = 4*CO2 + 6*H2O

If need other format (no txt -> doc/docx/pdf e.t.c) - I'll do it.
