thats all i can read the rest is blurry
Answer:
Ask the teacher
Explanation:
Ask if you have to clean up or if you are not prepared for an experiment
Answer:
m
Explanation:
C = Fλ
C: Speed of light =
m/s
f: Frequency (Hz)
λ: Wavelength (m)
Rearrange formula for wavelength:
C/F = λ

To find AH°rxn, we use the following equation:
What we're going to do is to sum the enthalpy of the products and then substract with the enthalpy of the reactives:
As you can see, we need to multiply by the coefficients of the reaction.
Now, just replace the values of the table:
So the answer is -822.2kJ/mol.
For b:
Now, just replace the values of the table:
The answer for b is -1036kJ/mol.
