Tips for the Diploma Flashcards
1
Q
Which types of molecules have ionic bonds and which have covalent?
a. organic
b. inorganic
A
organic compounds (i.e. compounds without metals) have covalent bonds (electrons are shared) inorganic compounds (i.e. compounds with metals) have ionic compounds (electrons are transferred)
2
Q
Which produces more energy?
a. cellular respiration in cells (burning glucose in your body)
b. burning glucose over a flame
A
a. cellular respiration produces more energy because it occurs in a closed system and the water stays liquid (with the flame, water is turned to gas, which takes energy)
3
Q
What is an “alkyl” functional group?
A
alkyl = only made of carbon and hydrogen
ex. CH3
4
Q
If the K value is larger, does it means the products or reactants are favoured?
A
products
larger K means higher concentration of products
5
Q
What is the formula (ex. CnH2n+2) for alkane, alkene, alkyne?
A
alkane: CnH2n+2
alkene: CnH2n
alkyne: CnHn
