Answer:

ν ≈ 4.7 × 10¹⁴ Hz

General Formulas and Concepts:

<u>Chem</u>

Speed of Light = Wavelength times Frequency

  • c = λν
  • c = 3.0 × 10⁸ m/s

Explanation:

<u>Step 1: Define</u>

λ = 6.4 × 10⁻⁷ m

<u>Step 2: Solve for ν </u>

3.0 × 10⁸ = 6.4 × 10⁻⁷ · ν

ν = 4.6875 × 10¹⁴ Hz

<u>Step 3: Check</u>

<em>We are given 2 sig figs. Follow sig fig rules.</em>

4.6875 × 10¹⁴ Hz ≈ 4.7 × 10¹⁴ Hz

For the reaction 2 HCl + Ca ( OH ) 2 ⟶ CaCl 2 + 2 H 2 O how many grams of calcium hydroxide, Ca(OH)2, are needed to react comple
kari74 [83]

Answer: 65.38g of Ca(OH)2 is needed

Explanation:

From The equation of reaction

2 HCl + Ca ( OH ) 2 ⟶ CaCl 2 + 2 H 2 O

NB: Molar mass of HCl= 1+35.5=36.5

Ca(OH)2= 74

From The stoichiometric equation

2mol of HCl(36.5×2=73) require 1mol of Ca(OH)2 (74g)

Hence 64.5g of HCl will require 64.5×74/73= 65.38g of Ca(OH)2
