Answer:
Wavelength = 9.4×10⁹ m
Explanation:
Given data:
Frequency of radiation = 3.2×10⁻² Hz
Wavelength of radiation = ?
Solution:
Formula:
Speed of light = frequency ×wavelength
Speed of light = 3×10⁸m/s
Now we will put the values in formula.
3×10⁸m/s = 3.2×10⁻² Hz × wavelength
Wavelength = 3×10⁸m/s /3.2×10⁻² s⁻¹
Wavelength = 0.94×10¹⁰ m
Wavelength = 9.4×10⁹ m
Hello,
You balanced the equation and then you have to set up what is called a psychometric equation for each reactant so that you get the same unit for each in order to compare the two. so for (calcium hydroxide) = 78.5 g ÷ (40.1 + 32 + 2) = 1.0593 mol * Note: I just broke it down in my own science way..u can just get the molar mass of calcium hydroxide which is approx 74 g/mol
Hope this helps

Explanation:
All the data related to the potential energy diagram is shown in the attached image.
Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).
Enthalpy change (ΔH) is the difference in energy between reactants and products.
ΔH = E of products - E of reactants.
Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as
From the image, the points marked represents:
Point A represents the potential energy of the reactants.
Point B represents the intermediate state or transition state in a reaction.
Point C represents the potential energy of the products.
Arrow D represents the activation energy of the reaction.
Arrow E represents the enthalpy of the reaction.
Hence, arrow E represents the enthalpy of the reaction.
