Answer:
C.
Explanation:
Iron is most likely to form a precipitation reaction.
Answer:
Frequency = 1.25 ×10¹³ Hz
Explanation:
Given data:
Wavelength of light = 24.0 μm (2.4 ×10⁻⁵ m)
Frequency = ?
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light /wavelength = frequency
Frequency = 3×10⁸ m /s /2.4 ×10⁻⁵m
Frequency = 1.25 ×10¹³ s⁻¹
s⁻¹ = Hz
Frequency = 1.25 ×10¹³ Hz
