guys i feel like the way im doing it is hard to see? where do I label them
what do i do in the case that I cant do dots and crosses for all of them like in the case here if carbon is an x then that mean hydrogen would be a dot but then does that mean oxygen is x and bonds with carbon? so I drew dots without filling them in but the book shows this so now im confused
guys my friend just told me a lot of the material my school taught us is no longer part of the material like thermocouples? is this true its no longer part of the exam?
my notes say red to yellow but the mark scheme keeps changing sometimes its orange in acid sometimes its red sometimes its yellow in base sometimes its orange in base. what do i put??
and each mark scheme only allows one answer too so im confused now
sorry this might be silly to ask but how is the resistance decreasing in the lamp?
