Answer: longer wavelength and lower energy.
Explanation:
1) The wavelength is inversely related to the frequency. So, an electromagnetic wave with lower frequency will have longer wavelength.
This is the formula for electromagnetic waves:
λ = c / ν
where λ is the wavelength, c is the speed of light, and ν is the frequency.
2) Energy is directly related to the frequency.
This is the formula E = hν,
where E is the energy, h is Planck constant, and ν is the frequency.
So, the lower the frequency the lower the energy.
3) Conclusion:
<span>An electromagnetic wave that has a lower frequency than infrared radiation will have longer wavelength and lower energy than the infrared radiation</span>
The Bohr model is the basis for chemistry
Answer:
20, 50, 25
Explanation:
I just figured it out somehow in my brain.
Answer: 4g/cm^3 or 4000g/L (4kg/L)
Explanation:
I'm not sure what units the question intended so I put both. For the first one, the equation for density is mass/volume so I divided the 20g by 5cm^3 to get 4g/cm^3. Just in case those aren't the intended units for volume and is instead liters, one cm^3 equals one ml. In addition, there are 1000ml in every liter so you can determine the amount per liter by multiplying 4g/ml by 1000 to get 4000g/L or 4kg/L.
I hope this helps.
Answer:
NaNO₃
KNO₃
Ca(NO₃)₂
Explanation:
The possible cations for the salt. = Na⁺ , K⁺ , Ca²⁺
The anion for which the formula has to written = NO₃⁻
The salt is of white color.
The possible salts may be:
<u>NaNO₃ </u>
<u>KNO₃</u>
<u>Ca(NO₃)₂</u>
Missy Mae can have one of these salts.
The color of NaNO₃ is from transparent to white.
The color of KNO₃ is white.
The color of NaNO₃ is from white to light grey.
