The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin is the base unit of temperature in the International System of Units.
Synthesis or a combination reaction. Two of the reactants form one final product in the end.
The given information in the question is :
Frequency = 170 Hz
1 Hz = 
Frequency = 170 
Wavelength given = 2 m
Speed is unknown which we need to calculate.
Speed can be calculated by using the formula : Speed = wavelength X frequency
By plugging the value of wavelength and frequency in the above formula we get :
Speed = 
Speed = 340
Answer:
Iron (iii) chloride reacts with copper (ii) sulfate to give iron sulfate and copper chloride.
Explanation:
The balanced equation of iron iii chloride+ copper ii sulfate is as follows.

I looked it up and i saw tht it was ions and electrons.
hope this helps you!! :)
