Decrease in predators because then the wild turkeys won't be killed.
25 sugar because the mass should be equal on both sides
Answer: Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the shells causes different wavelengths to be released... hence, mono-electronic hydrogen has many spectral lines.
Explanation: sry its late
Mass of oxygen = 143,1g - (53,4g + 16,9g + 43g) = 29,8g
If 143,1g ------ is ------ 100%
so
29,8g ------- is ------ %O
%O = (29,8g*100%) / 143,1g = 20,82%
