Question

a single displacement chemical reaction is*
release of heat during a reaction.
joining together of two elements to form a
compound.
breaking down of a substance into simpler
substances.
displacement of one element in a compound
by another element.

cell wall is found only in plant cells. *
true
false

classify the following equation as to reaction *
type.
agno3 + nacl → nano3 + agcl
decomposition
synthesis
double displacement
single displacement

Explanation:

1. A single - displacement reaction is defined as the displacement of one element in a compound by another element.
2. Cell walls are also found in some bacteria, fungi, and algae cells, not just plant cells.
3. In the reaction \(AgNO_3 + NaCl

ightarrow NaNO_3+AgCl\), the \(Ag^+\) and \(Na^+\) ions exchange their partners (\(NO_3^-\) and \(Cl^-\)), which is characteristic of a double - displacement reaction.

Answer:

1. displacement of one element in a compound by another element.
2. False
3. double displacement
