The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃
<h3>Activity Series</h3>
From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.
Let us look at each of the given options;
A) Ag + FeCl₃
From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.
B) Zn + CaO
Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.
C) Ba + Na₂CO₃
Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.
D) Cr + KNO₃
Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.
Complete question is;
Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt
A. Ag + FeCl₃
B. Zn + CaO
C. Ba + Na₂CO₃
D. Cr + KNO₃

Answer:
Answer: <u> </u><u>3</u><u>0</u><u>%</u><u> </u><u> </u><u>decrease</u><u> </u>
Explanation:

The answer would be 6 even numbers greater than 2 and less than 20 would be equal to the sum of two prime numbers.
explanation:
even numbers greater than 2 and less than 20 would be 4, 6, 8, 10, 12, 14, 16, and 18.
the prime numbers we can use would be 2, 3, 5, 7, 11, and 13.
13+3=16 and 13+5=18.
11+3=14.
7+3=10 and 7+5=12.
finally, 5+3=8.
that makes a total of 6 even numbers.
