The answer is a.commensalism
Answer:
The correct option is;
a) The resulting mixture was cloudy
Explanation:
Here we have the initial color as
1. Colorless and
2. Dark blue
We analyze each of the results as follows
a) The resulting mixture was cloudy
A cloudy mixture forming when the two liquids are mixed is most likely due to the formation of a suspension from a new substance That is a new compound is formed
b) The total volume of the mixture was equal to the sum of the initial volumes.
Here since there is no change in the physical properties as the volume of the mixture is the sum of the volumes of the constituent then there is unlikely to be a chemical change
c) The resulting liquid was light blue
Here, the observation is more of a physical change
d) The liquids formed two separate layers in the beaker.
This is an indication that there was no mixing of the liquids hence no reaction or chemical change.
The characteristics of mixtures are:
a) they are made up of two of more substances
b) the two substances can be separated by physical means
c) there are two kinds of mixtures : homogenous and heterogenous
d) homogenous mixtures do not have any physicaly distinguished boundary
