The answer is the fourth one
D) Reaction rate rate
Answer:
B. AgNO₃
Explanation:
If the products contain Ag, Cl, K, and NO₃, then this means that these were also the reactants. Remember that matter cannot be created nor destroyed in a chemical reaction, so whatever elements in the reactants were used, would be found in the products. In other words, an element does not change into another.
AgNO₃ + KCl → AgCl + KNO₃
C, because vinegar ph scale is 2.5
The chlorine isotope with 18 neutrons has an abundance of 0.7577 and a mass number of 35 amu. To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together.
