4C₃H₅(NO₃)₃
------> 12CO₂
+ 6N₂ + 10H₂O + O₂
mol of CO₂ = 
= 
mol ratio of CO₂ : C₃H₅(NO₃)₃
12 : 4
∴ if mole of CO₂ = 0.568 mol
then " " C₃H₅(NO₃)₃ = 
= 0.189 mol
∴ mass of nitroglycerin = mole * Mr
= 0.189 mol * 227.0995 g / mol
= 43.00 g
C.
Protons is 8 so the atomic number will be 8.
Number of neutrons= atomic mass - atomic number
16-8 = 8.
2 and 3 are not possible because energy cannot be created nor destroyed. In order to break bonds, energy must be absorbed, so 1 is your answer!
Thomson
In his model discovered electron which has negative charge whereby this electrons were positioned throught the atom surrounded by a soup of positive balance the negative charge of electron
Rutherford
In his model concluded that atom is made up of central charge surrounded by orbiting electrons.
