Answer;
D.
infrared, visible, ultraviolet
Explanation;
Electromagnetic waves are types of waves that do not require a material medium for transmission. An electromagnetic spectrum arranges these electromagnetic waves in the order of increasing frequency and decreasing wavelength.
The spectrum consists of , Radio waves, microwaves, infrared, visible light, UV light, X-rays and Gamma rays; arranged in order of decreasing wavelength and increasing frequency.
Radio waves have the longest wavelength but the lowest frequency, while gamma rays have the lowest wavelength but the largest frequency.
Answer:
0.264moles
Explanation:
number of moles= given mass/molar mass.
Molar mass of Cu2SO4= 63.5+32+4(16)=159.5
moles(n)=42.2/159.5= 0.264moles
