The Atomic number for the Element H is 1.
Hope this helps. :)
The amount of heat required is 9.0 kJ.
<em>q = mC</em>Δ<em>T
</em>
Δ<em>T</em> = <em>T</em>_f – <em>T</em>_i = 65 °C – 32 °C = 33 °C
<em>q</em> = 65 g × 4.184 J·°C⁻¹g⁻¹ × 33 °C = 9000 J = 9.0 kJ
Percentage O: 69.54
Percentage N: 30.46
Dividing each percentage by the components molecular weight:
Oxygen: 69.54 / 16 = 4.35
Nitrogen: 30.46 / 14 = 2.18
Ratio of nitrogen to oxygen = 1 : 2
Empircal formula: NO₂
Mass of empirical formula = 46
Repeat units = 92 / 46 = 2
Molecular formula = N₂O₄
In order to find the answer you must plug in the information to the frequency equation,
. C is the speed of light, 3.0 x 10^8. By plugging in the information you receive a frequency of
3.0 x 10^7 hz.
