City A: 100° F
City B: -29° F

100 - (-29) ==> 100 + 29 = 129 degrees difference.

The different between City A and B is 129° F

Hope this helps!

Consider the reaction 5Br−(aq)+BrO−3(aq)+6H+(aq)→3Br2(aq)+3H2O(l) The average rate of consumption of Br− is 1.20×10−4 M/s over t
dexar [7]

Answer:

0.720 M/s

Explanation:

Let's consider the following balanced equation.

5Br⁻(aq) + BrO⁻₃(aq) + 6H⁺(aq) → 3 Br₂(aq) + 3H₂O(l)

The molar ratio of Br⁻ to Br₂ is 5:3, that is, when 5 moles of Br⁻ are consumed, 3 moles of Br₂ are produced. If the average rate of consumption of Br⁻ is 1.20 × 10⁻⁴ M/s, the average rate of formation of Br₂ is:

\frac{1.20molBr^{-}}{L.s} .\frac{3molBr_{2}}{5molBr^{-}} =\frac{0.720molBr_{2}}{L.s}

Photon energy is proportional to which of the following quantities? speed of light in a vacuum frequency of the light emitting t
charle [14.2K]

Answer:

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.

Explanation:

Energy of the photon is given by expression:

E=h\times \nu=\frac{hc}{\lambda }

E = Energy associated with the photon

\nu  =  frequency of the light

h = Planck's constant =6.626\times 10^{-34} J s

c = speed of the light in vacuum = constant

\lambda =Wavelength of the photon

E\propto \nu

The energy of the photon is directly proportional to the  frequency of the light emitting the photon.
