Comments on November Grade 10 (P2)
Any comments on the above-mentioned paper or clarity on the memorandum? The memo for this paper is available here.
Intermolecular bonding is between molecules - the atoms are of different molecules, such as the hydrogen bond between an O atom of one molecules and a H atom of another molecule in the H2O molecules: (H2O) -- (H2O)
Whereas intramolecular bonding takes place when the atoms are of the same molecule, such as the covalent bond between the Hydrogen and Oxygen within the water molecule.
Vraag 5.3. Is dit intermolekulere kragte? Dan is daar nie 'n antwoord nie.
ReplyDeleteDis vraag 5.2.1 (c). Watter twee intermolekulere kragte?
ReplyDeleteQuestion 5.2.1(c) there is no answer, or am I wrong?
Dry ice consists of CO2 molecules and sulphur of S8 molecules. Between molecules are intermolecular forces.
DeleteThe memo seems to be correct.
DeleteQ1.6 Has no correct answer?
ReplyDeleteSee next comment for the answer to this question. Thanks Janetta.
DeleteA Ca2+ ion has 18 electrons and so does a Cl- ion.
ReplyDeleteI am still not satisfied with Q 5.2.1.(C). The forces are intramolecular and not intermolecular.
