N2O5 gives 2NO2 plus 0.5 O2. Rate for first order reaction. K = 5 * 10/10000 R = 0.30 mol/liter after 40 min. What is the [C] of N2O5 and NO2 ?

Consider the state |ÏˆâŒª = âˆš2 |0âŒª + âˆš2 |1âŒª from the previous question. To estimate the phase Î¸, we measure |ÏˆâŒª in the sign basis. What is the probability that the outcome of the measurement is +? Recall that eiÎ¸ = cos Î¸ + i sin Î¸

Suppose that a qubit is in the state |Ï†âŒª = a|0âŒª + 1 âˆ’ a2 |1âŒª where a âˆˆ [âˆ’1, 1]. If we ï¬rst perform a standard basis measurement on this qubit and then perform a |uâŒª, |uâŠ¥ âŒª-basis mea- âˆš surement where |uâŒª = b|0âŒª + 1 âˆ’ b2 |1âŒª...
