Sarah measures out 151 grams of SO2. How many miles is this? Express your answer to three significant figures
elena-s [515]

150 g SO₂ = 2.36 mol SO₂

M_r = 32.06 + 2×16.00 = 32.07 + 32.00 = 64.06

Moles of SO₂ = 151 g SO₂ × [1 mol SO₂/64.06 g SO₂] = 2.36 mol SO₂

Electromagnetic radiation with wavelength of 745 nm appears as red lighting to human eye. the energy of the photon is this light
trapecia [35]

Answer:The energy of the photon is this light is 2.66\times 10^{-19} Joules.

Explanation:

Wavelength of the electromagnetic radiation = 745 nm =7.45\times 10^{-7} m

1m =1\times 10^{-9}nm

Energy of the photon will be given by Plank's equation:

E=\frac{hc}{\lambda }

E=\frac{6.626\times 10^{-34} J s\times 3\times 10^8 m/s}{7.45\times 10^{-7} m}

E=2.66\times 10^{-19} Joules

The energy of the photon is this light is 2.66\times 10^{-19} Joules.

If the natural abundance of Br−79 is 50.69 %, what is the natural abundance of Br−81?
Alexxandr [17]
The natural abundance of bromine in general in nature is 100%.
This means that:
the natural abundance of Br-79 + the natural abundance of Br-80 = 100

We know that the natural abundance of Br-79 is 50.69%. This means that the natural abundance of Br-80 is the rest of the 100%.

Natural abundance of Br-80 = 100% - 50.69% = 49.31%
