Question 6.1.3
Mark as follows: If reagents are correct, first mark. If products are correct, second mark. Now look at balancing; if both coefficients for reagents are correct (whole numbers), third mark. If both coefficients for products are correct, fourth mark. The two marks for balancing are forfeited if either the reagents or the products are incorrect.
Question 8.2.1
The question could be confusing. Award "transverse" and "longitudinal". In other words, if anyone of the two terms is used, the mark is awarded.
Question 10.2 and 10.4
Stay on the memo. No "positive marking" from 10.2 to 10.4.
