Answer:
C.)
Explanation:
The general equilibrium expression looks like this:
In this expression,
-----> K = equilibrium constant
-----> uppercase letters = formulas
-----> lowercase letters = balanced equation coefficients
Solids are not included in the expression, so Ca(HCO₃)₂(s) and CaO(s) should be left out. The products should be in the numerator and the reactants are in the denominator. This makes the expression:
<----- Equilibrium expression
<----- Insert gaseous formulas
<----- Insert coefficients
Answer:
4.55 m
Explanation:
Given data
- Frequency (ν): 66.0 MHz = 66.0 × 10⁶ Hz = 66.0 × 10⁶ s⁻¹
- Speed of light (c): 3.00 × 10⁸ m/s
We can determine the wavelength of the radio waves using the following expression.
c = λ × ν
λ = c/ν
λ = (3.00 × 10⁸ m/s)/66.0 × 10⁶ s⁻¹
λ = 4.55 m
The wavelength of the radio waves is 4.55 m.

Nomenclature and common formula. When part of a salt, the formula of the acetate ion is written as CH3CO2−, C2H3O2−, or CH3COO−. Chemists abbreviate acetate as OAc− or, less commonly, AcO−. Thus, HOAc is the abbreviation for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate.
