Answer:
violet
Explanation:
When an electron interacts with visible light, energy is transferred from the photon to the electron.
The most accurate (lowest error) measurement of momentum (or speed) of an electron is obtained using a photon of high energy and low wavelength.
Violet light which lies at the high energy end of spectrum is most suitable.
H2O2 Is a chemical compound called hydrogen peroxide
Answer:
So, the mole ratio between sodium and sodium oxide is 2:1=2
Explanation:
<span>Use Root mean square speed formula:
vrms = Sqrt (3RT/M)
T - temperature in K = 273K - 21CÎż = 252K
R- molar gas constant = 8.31J/Kmol
M - molar mass of a molecule
MN2 = 14x2 = 28 g/mol
MO2 = 16 x 2 = 32 g/mol
MO3 = 16 x 3 = 48 g/mol
Having all info now, you can calculate root mean square speed,vrms ,
for every molecule by using the aboveequasion and only changing M value.</span>
