Nthe following reaction, how many grams of nitroglycerin c3h5(no3)3 will decompose to give 120 grams of water?
4c3h5(no3)3(l) 12co2(g) + 6n2(g) + 10h2o(g) + o2(g)

the molar mass of nitroglycerin is 227.0995 grams and that of water is 18.0158 grams.

Answer : The mass of nitroglycerin decompose is 604.1 grams.

Solution : Given,

Mass of = 120 g

Molar mass of = 18.0158 g/mole

Molar mass of = 227.0995 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 10 moles of produced from 4 moles of

So, 6.66 moles of produced from moles of

Now we have to calculate the mass of

Therefore, the mass of nitroglycerin decompose is 604.1 grams.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
