Answer:
D. 2.5 x 10 ^-14 Hz
Explanation:
Use wavelength formula: v = f x wavelength
Rearrange formula for frequency.
f = wavelength / v
f = 7.6 x 10 ^-6 / 3.00 x 10 ^8
f = 2.5 x 10^-14 Hz
Answer:
it will wilt and die
Explanation:
If you water a plant with salt water, it will wilt, and will eventually die. This is due to the fact that the salt water is a hypertonic solution when compared to the plant cells, and water inside the plant cells will diffuse by osmosis out of the cells in order to reduce the concentration of the salt solution
I think ionic ?
i dont know so dont take my anwser yet
CoCl₂(s) → Co²⁺(aq) + 2Cl⁻(aq)
n(CoCl₂)=0.27 mol
n(Co²⁺)=n(CoCl₂)
n(Cl⁻)=2n(CoCl₂)
n=n(Co²⁺)+n(Cl⁻)=3n(CoCl₂)
n=3*0.27=0.81 mol
Answer:
CO
Explanation:
the rest are elements. CO is made up of one carbon atom and one oxygen atom
