Witam was więc rozdzieliam te dużo zadań na kilka ;)
1) M RCOONa = 110
110= R + 12 + 2*16 + 23
R=43
R = CnH2n+1
43=12n+2n + 1
n=3
wzór półstrukturalny: CH3-CH2-CH2-CO-CH3
wzór sumaryczny: C5H10O
2) a) -2,4
b) -3
c) Cu(OH)2 + 2NaOH ->Na2 [Cu(OH)4]
Cu(OH)2 + 2OH- -> [Cu(OH)4] 2-
2CH3COOH + Cu(OH)2 -> (CH3COO)2Cu + 2H2O
H+ + OH- ->H2O
zadanie 30
mRCOONa = 110u
mCOONa = 67u
mR = 43u
R to CnH2n+1
mCnH2n+1 = 12 + 1(2n + 1) = 14n + 1
14n + 1 = 43
14n = 42
n = 3
Wzór półstruktoralny CH₃-CH₂-CH₂-CO-CH₂ - 2-pentanon
zadanie 31
a) 1, 2 i 4
b) 3
c)
2NaOH + Cu(OH)₂ --> Na₂[Cu(OH)₄]
Cu(OH)₂ + 2OH⁻ --> [Cu(OH)₄]²⁻
2CH₃COOH + Cu(OH)₂ --> (CH₃COO)₂Cu + 2H₂O
2H⁺ + Cu(OH)₂ --> Cu²⁺ + 2H₂O
