In a chemical reaction equation.. There must be redox reaction taking palce.. So oxidation and reduction reactions will be happening on both sides of the equation.. You can separate the oxidation and reduction equations in halves. . So there will be one half oxidation equation and the other half reduction equation of the reaction.
Mass of water = density x volume
Mass of water = 0.413 x 1
Mass of water = 0.413 g
Energy absorbed = mCpΔT
Energy = 0.413 x 4.184 x 76.5
Energy = 132.2 J
Using Planck's equation:
E = nhc/λ
132.2 = (n x 6.63 x 10⁻³⁴ x 3 x 10⁸) / (13.3 x 10⁻²)
n = 8.84 x 10²⁵ photons
Using the significant figure it would be 27.3
The answer is Na < Cl
Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.
