Answer:
Explanation:
Given that
Speed of neon = 350 m/s
Un-certainity in speed= (0.01 ÷ 100) × 350
= 0.035 m/s
As per heisenberg uncertainty principle
....... (i)
substituting the values in equation (i)
In terms of rNe i.e 38 pm =
Therefore the smallest possible length of the box inside in which the atom could be known for locating with certainty is
Answer:
−2399.33 kJ
Explanation:
If NH₄NO₃ reacts with fuel oil to give a ΔH of -7198 for every 3 moles of NH₄NO₃
What is the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction
∴ For every 1 mole, we will have of the total enthaply of the 3 moles
so, to determine the 1 mole; we have:
= −2399.33 kJ
∴ the enthalpy change for 1.0 mole of NH₄NO₃ in this reaction = −2399.33 kJ
