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

We dont know without all the info
Using the accrual method, the unearned revenue as of December 31 is $12,000.
<h3>What is Unearned revenue?</h3>
Unearned revenue can be defined as the amount a company received from their client for the service they are yet too rendered.
Since the company has received full balance for the services not yet provided. The unearned revenue as of December 31 will be $12,000.
Reason been that the amount that the client paid the company is for a year-long contract, hence the $12,000 represent a prepayment amount for the service the company is yet too rendered to their client
Thus, using the accrual method, the unearned revenue as of December 31 is $12,000.
