I need help with this question, “Complete the sentence : if the mass remains the same while the volume of a substance , the density of the substance will . Options A. Decreases, decrease, B. Increases, decrease C. Increase, stay the same D. decreases, stay the same

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m

d is correct as long as you put the state each one it eg. (aq)

mg(no3)2(aq) + zn(s) > zn(2+)(aq) + ) + mg(s)

hope it !
