Answer:
1.58×10² nm
Explanation:
Given data:
Frequency of light = 1.90 ×10¹⁵ Hz
wavelength of light = ?
Solution:
Speed of light = wavelength × Frequency
Speed of light = 3×10⁸ m/s
3×10⁸ m/s = λ × 1.90 ×10¹⁵ Hz
Hz = s⁻¹
λ = 3×10⁸ m/s / 1.90 ×10¹⁵s⁻¹
λ = 1.58×10⁻⁷ m
meter to nm:
1.58×10⁻⁷ m ×10⁹ nm/ 1m
1.58×10² nm
Answer:
Weather and climate on Earth are determined by the amount and distribution of incoming radiation from the sun. For an equilibrium climate, outgoing longwave (infrared) radiation (OLR) necessarily balances the incoming absorbed solar radiation (ASR), so that the Net =ASR-OLR =0. There is a great deal of fascinating atmosphere, ocean and land phenomena that couple the ASR and OLR and the balance is only for the annual mean, not individual months or seasons. Incoming radiant energy may be scattered and reflected by clouds and aerosols, or absorbed in the atmosphere. The transmitted radiation is then either absorbed or reflected at the Earth’s surface. Radiant solar (shortwave) energy is transformed into sensible heat, latent energy (involving different water states), potential energy (involving gravity and height above the surface (or in the oceans, depth below)) and kinetic energy (involving motions) before being emitted back to space as longwave radiant energy. Energy may be stored for some time, transported in various forms, and converted among the different types, giving rise to a rich variety of weather or turbulent phenomena in the atmosphere and ocean. Moreover, the energy balance can be upset in various ways (so the Net ≠ 0), changing the climate and associated weather.

Answer:
Major product ethoxide ion
Explanation:
- Sodium hydride acts as a strong base towards ethanol.
- Hydride ion abstracts one proton from -OH group in ethanol to produce sodium ethoxide and hydrogen gas.
- It is an example of acid-base reaction where sodium hydride acts as a base and ethanol acts as an acid
- Structure of major organic product i.e. ethoxide ion has been shown below.
Answer:
We need a picture of the problem to solve!
Explanation:
<span>Hello!
We have the following data:
W (molality) = ? (in Molal)
m1 (mass of the solute) = 14.7 g
m2 (mass of the solvent) =? (in Kg)
d (</span><span>solvent density) = 1,00 g/mL
</span>V (volume of the solvent) = 150 mL
<span>The mass of the solvent will be found by the following formula
</span>
<span>
</span>
<span>
M1 (Molar mass of solute - </span>C6H12O6) = ?
C = 6*12 = 72 u
H = 12*81 = 12 u
O = 6*16 = 96 u
------------------------
M1 (Molar mass of solute - C6H12O6) = 72+12+96 = 180 g/mol
<span>Now, let's find Molality, applying the above data to the formula, let's see:
