Samenvatting Scheikunde hf 2 rekenen
Paragraaf 2..2:
Mol = een maat voor het aantal deeltjes.
m m
Formule: n = →
M n xM
M = molaire massa ⇒ de atoommassa (binas)
m = massa ⇒ afgewogen hoeveelheid (gram)]
n = hoeveelheid stof (mol)


Grootheid: Symbool: Eenheid: Symbool:

Chemische n mol mol
hoeveelheid

Molaire massa M gram per mol g/mol

Massa m gram g


Dichtheid p:
V Vxp=m M n=m:M n
Volume Massa Chemische hoeveelheid
V=m:p m=Mxn
ml of L g of kg mol


NA = getal van avogadro ⇒ constante waarde = 6,02 x 10 23




Reactievergelijkingen:
- Ijzer verbrand tot ijzeroxide → reactie met zuurstof (O 2)
● Fe + O2 → Fe2O3
● 4 Fe + 3 O2 → 2 Fe2 2 O3
- Propaan verbrand volledig → C ⇒ CO2, H ⇒ H2O
● C3H8 + O2 → CO2 + H2O
● C3H8 + 5 O2 → 3 CO2 + 4 H2O
- Propaan verbrand onvolledig → C ⇒ CO, H
⇒ H 2O
● C3H8 + O2 → CO + H2O
● 2 C3H8 + 7 O2 → 6 CO + 8 H2O
- Fosfortrichloride ontleed in zijn elementen
● PCl3 → P + Cl2
● 2 PCl3 → 2 P + 3 Cl2

Weet je C kun je H berekenen → Cgetal x 2 + 2
