Answer:
density =mass/ volume
Explanation:
isn't this physics ...
so is the mass is 19 g and volume = 25 ml first convert to same units (g/cm3)
1ml = 1cm3
same units so no need to convert
19 divided by 25 = 0.76
0.76 g/cm3
pls give me brainliest
Magnese sulfide would be MnS
Answer:
λ = 1×10²⁶m
Explanation:
Given data:
Wavelength of radiation = ?
Frequency of radiation = 3×10⁻¹⁸Hz
Solution:
Formula:
c = f × λ
c = speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 3×10⁻¹⁸Hz × λ
λ = 3×10⁸ m/s / 3×10⁻¹⁸s⁻¹
λ = 1×10²⁶m
Answer:
yeild solid iron
Explanation:
When two solutions of ionic compounds are mixed, a solid may form. This type of reaction is called a precipitation reaction, and the solid produced in the reaction is known as the precipitate.
