Single replacement or single displacement reactions
Explanation:
In a single replacement or displacement reaction, the activity series is useful in predicting whether the reaction will take place or not.
- In this reaction type, one substance is replacing another.
C + DE → CD + E
- The relative positions of the two elements in the activity series provides the driving force for the single replacement reaction.
- An element high up in the series will displace one that is lower in the series because it is more reactive.

The general rule followed is that if electronegativity difference is greater than 2, then it is considered an ionic bond. An ionic bond is a type of bond characterizing a transfer of electrons within a bond. Common examples are salts which adds that ionic bonds are common between a metal and a nonmetal. Therefore, the best answer from above is letter B.
Answer:
pOH = 0.3
Explanation:
As KOH is a strong base, the molar concentration of OH⁻ is equal to the molar concentration of the solution. That means that in this case:
With that information in mind we can<u> calculate the pOH </u>by using the following formula:
Answer:
ork out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V).
If you have U, A and T, use V = U + AT.
If you have S, U and T, use V = 2(S/T) - U.
If you have S, U and A, use V = SQRT(U2 + 2AS)
