Answer : The correct option is, (D) double replacement reaction
Explanation :
Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.
It is represented as,

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.
It is represented as,

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.
It is represented as,

In this reaction, A is more reactive element and B is less reactive element.
Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.
It is represented as,

(X and A are the cations, Y and B are the anions)
The given reaction is:

This reaction is a double displacement reaction.
The only difference between 5.0 and 5.00 is the that, 5.0 has 2 significant digits and 5.00 has 3
Answer:
C) Carla participated in an artistic activity, while Maurice participated in a scientific activity.
Explanation:
Scientific activities involve making observations, which ultimately leads to the series of steps that aims at solving the observed problem or answering a question that arises from the problem. This is the case of Maurice who is observing and recording information about ants in order to solve a curiosity (about what they feed on).
However, on the other hand, Carla is given a pictorial representation of the ants and what they carry. It is not based on curiosity or to answer a question about the ants but rather for decoration or aesthetic purposes, which is what makes her activity artistic.
