Answer:
B. Line 2 has a mistake
Explanation:
1. All electromagnetic waves are made of both electric and magnetic fields (hence the name electromagnetic).
2. All electromagnetic waves are transverse, and not longitudinal.
3. All electromagnetic waves can travel through space because they do not need particles to travel (like sound waves).
4. Electromagnetic waves all travel at the speed of light (299 792 458 m/s).
Answer:
A. 68°F
B. 293K
Explanation:
The temperature (celsius) = 20.0°C
A. Conversion of the temperature in celsius to fahrenheit.
This is illustrated below:
°F = 9C/5 + 32
C = 20°C
°F = 9C/5 + 32
°F = 9x20/5 + 32
°F = 36 + 32
°F = 68°F
B. Temperature (Kelvin) = temperature (celsius) + 273
Temperature (celsius) = 20°C
Temperature (Kelvin) = 20°C + 273
Temperature (Kelvin) = 293K

Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to solve this problem by firstly setting up the equilibrium expression for the given reaction, in agreement to the law of mass action:
![K=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Next, we plug in the given concentrations on the data table to obtain:
