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: The values for the constants are c=2, and d=-4.
explanation: We have the function f, defined as:
and
where c and d are constants.
So, if f is differentiable at x=2, then it must be continuos at x=2, therefore
Let's call this, equation 1.
On the other hand, we have that f is differentiable, therefore
and
so, we calculate
which, replacing in equation 1, gives us
Finally, the answer is that c=2, and d=-4.
Consumption has a high positive correlation with economic growth. Whether economic growth takes precedence over energy consumption or energy consumption boosts the economic growth have been examined in a number of studies yet empirical evidence is mixed and conflicting.

Apply Pythagorean theorem
Now
- DE=AB/3=12/3=4
- EF=BC/3=16/3=5.3
- DF=AC/3=20/3=6.6
