Verbindings E Chemiese Reaksies

Question 1

Definieer element:

Answer 1

ń Elenment is ń suiwer stof wat net uit een soort atoom bestaan

Question 2

Hoekomis elemente die kleinste boustene van verbindings?

Answer 2

Want n element kan nie deur chemiese metodes in eenvoudiger stowwe opgebreek word nie.

Question 3

Definieer Verbinding:

Answer 3

Ń suiwer stof wat uit 2 of meer verskillende atome bestaan,bv. Water het 2 waterstof atome en 1 suurstofatoom

Question 4

Wat toon n verbinding se chemiese formule aan?

Answer 4

N verbinding se chemiese formule toon aan watter element teenwoordig is in die verbinding en hoeveel atome van elke element daar in 1 molekuul is,bv. H2O

Question 5

Waaruit bestaan die atome van n elment?

Answer 5

3 subatomiese deeltjies(hoofdeeltjies):
- Protone(+)
- Elektrone(-)
- Neutrone(N)

Question 6

Watse lading het atome oor die algemeen?

Answer 6

Atome het oor die algemeen geen lading nie,@die totale aantal protone is gelyk aan die aantal totale elektrone
