Which equation represents a single replacement reaction that can occur? o F2 + 2NaCl → 2NaF + Cl2 .Zn + 2NaF → ZnF2 + 2Na o Cl2 + 2NaF → 2NaCl + F2 o Cu + 2NaCl → CuCl2 + 2Na​

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
