Answer:
ν ≈ 4.7 × 10¹⁴ Hz
General Formulas and Concepts:
<u>Chem</u>
Speed of Light = Wavelength times Frequency
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
The formula for hyposulfurous acid is H2SO2.
Answer:
Explanation:
to show how precise your measurements were.
Common salt besides being used in kitchen can also be used as the raw material for making washing soda and baking soda.
The overall balanced reaction for washing soda preparation:
2NaCl + CaCO3 → Na2CO3 + CaCl2
NaCl is sodium chloride or common salt
Na2CO3 is sodium carbonate or washing soda
CaCO3 is calcium carbonate or limestone
The overall balanced reaction for baking soda preparation:
NaCl + CO2 + NH3 + H2O → NaHCO3 + NH4Cl
Baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or appears as a fine powder.
NH3 is ammonia
CO2 is carbon (II) oxide
