#1
Front (Question)

Avogadro’s number

Back (Answer)

6.022x10^23 aka a 1 mole

#2
Front (Question)

molecular (formula) weight Ex: fructose aka C6H12O6

Back (Answer)

add up the masses of every atom in that molecular formula Ex: C=12, H=1, O=16 126+H12+16*6= 180

#6
Front (Question)

What is a combustion reaction?

Back (Answer)

a rapid reaction in which a hydrocarbon (CH) or an alcohol (OH) reacts with oxygen (O2)
