Answer:
endoplasmic reticulum (ER)
The answer is C) iron and oxygen. The reactants are on the left side of the equation
<span>The equation for the dissociation of acetic acid is:
CH3CO2H(aq) + H2O(l) <---> H3O+(aq) + CH3CO2-(aq)
pH = 0.5(4.74 - lg(0.5)) = 2.52
so
[H^+] = 3.02*10^-3 M = 3.02 mM</span>
Answer:
Decrease by the distance squared
Explanation:
<u><em>Gravitation formula:</em></u>

where
'F' is the force of attraction between the two bodies (Gravitational force),
'G' is the universal gravitational constant,
'M' is the mass of the first object,
'm' is the mass of the second object and
'r' is the distance between the centers of each object.
Hence, with the increase by distance between two objects , the gravitation decreases by the distance squared
