The law of conservation of mass say that, in a chemical reaction, the mass of the reagents will always be equal to the mass of the products. This is shown in the reaction given below.
- Mass of the reagent: 100 g.
- Mass of the products: 56 + 44 = 100 g.
prokaryotic cells is the answer
The POH of a 2.70 x10^-11 solution of lithium hydroxide(LiOH) is 10.6
calculation
POH= -log (OH-)
write the equation for dissociation of LiOH
LiOh---> Li^+(aq) + OH-(aq)
from the equation above the ratio LiOH: OH is 1:1 therefore the concentration of OH- =2.70 x10 ^-11
that is - log (2.70 x10^-11) = 10.6
A model of an atom is much bigger than a real atom, but the model of the solar system is obviously much smaller.
