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

The answer is C, they show info about years in the past, present and future, ask your teacher or any website and they can show you a line graph. :)
Food-grade lubricants must perform the same technical functions as any other lubricant: provide protection against wear, friction, corrosion and oxidation, dissipate heat and transfer power, be compatible with rubber and other sealing materials, as well as provide a sealing effect in some cases.
The statements describing the southern economy in the antebellum era include 'it was primarily agricultural', 'it relied heavily on slave labor' and 'it produced mostly cotton and tobacco', It was a primary economy.
<h3>The southern economy in the antebellum era</h3>
In the USA, the economy of the antebellum era underwent an acceleration of economic growth.
This economy was characterized by the presence of slaves in the southern states and the family-farm of the free states.
In these southern states, the economy was directly tied to cotton and tobacco production.

Answer:
-5x+4y=20
Explanation:
A line passes through point (-8, -5) and has a slope of 5/4
Write an equation in Ax+By=C form for this line.
Use integers for A, B, and C.
So we have a point and a line we can use the point slope formula
y-y1=m(x-x1)
y-(-5)=(5/4)(x- -8)
y+5=(5/4)(x+8)
y=5/4x+10-5
y=5/4x+5
Then we multiply 4 both sides
4y=5x+20
-5x+4y=20
