The famous bite mark evidence was crucial in this case because there was practically no other evidence to work from since Bundy was meticulous in cleaning up the scene.
Answer:
An educated guess based on what you already know.
Explanation:
Moles of NO formed : 0.833
<h3>Further explanation</h3>
Given
2.5 moles of NO2
Required
moles of NO formed
Solution
Reaction
3 NO₂(g) + H₂O(l) = 2 HNO₃(aq) + NO(g)
The reaction coefficient in a chemical equation shows the mole ratio of the compounds in the reactants and products
From the equation, mol ratio of NO₂ and NO = 3 : 1, so moles of NO :
The moles of nitrogen in 0.30 mole of caffeine is calculated as follows
write the chemical formula = C8H10N4O2
for this case from the chemical formula we have 4 atoms of nitrogen in caffeine
therefore moles of nitrogen in caffeine = 4 x0.30 =1.2 moles
