V = 38.55 mL - 15.75 mL = 22.80 mL = 22.80 cm³
D =
=
= 1.392 g/cm³
Answer:- The wavelength is and the right option is D.
Solution:- Wavelength is inversely proportional to the frequency and the equation is:
where, is the wavelength, c is the speed of light and is frequency.
Frequency is and the speed of light is .
Since,
So,
Let's plug in the values in the equation:
Hence, the right option is D) .
I believe the answer is Magnetic Force
Answer:
Explanation:
4. Reduction reaction as Cu++ is reduced to Cu.
5. Double displacement reaction as the CO3-- replaces 2x OH-
6. Precipitation as two solutions combine to form a precipitate and a secondary product.
