Question
A single displacement chemical reaction can only occur if which of the following is true?There is no uncombined reactant element presentThe uncombined reactant element has a high enough degree of chemical activityThe uncombined reactant element can displace oxygen in waterThe uncombined reactant element has a high boiling point
Solution
A single displacement chemical reaction can only occur if the uncombined reactant element has a high enough degree of chemical activity.
Here's why:
In a single displacement reaction, one element is replaced by another in a compound. This can only happen if the uncombined reactant element is more reactive than the one it's trying to displace.
The reactivity of an element is determined by its ability to lose or gain electrons, which is referred to as its chemical activity. Therefore, for a single displacement reaction to occur, the uncombined reactant element must have a high enough degree of chemical activity to displace another element in a compound.
The presence of uncombined reactant element, its ability to displace oxygen in water, or its boiling point do not directly influence whether a single displacement reaction can occur.
