Answer: the strongest base will be A) HX(aq)
Explanation:
The cationic part of the base is formed from the cation in the weak acidic salt solution, (say Na2CO3= HY, and H= Na) i.e H+, whereas the anionic part of the base comes from the the weak base ( say NH4OH= HX, and X= OH-)
Then the strong base formed will be HX
Tying marshmallows utilising toothpicks together was difficult about building the model
Building the construct was challenging because of the toothpicks used to connect the marshmallows.
• The Salt Model consists of three layers that can be stacked on top of one another to form a NaCl unit cell.
Using the model in two different orientations is possible if the layers are connected.
• As shown by the salt model, the majority of basic inorganic compounds are composed of ions that interchange endlessly rather than discrete molecules.
Little marshmallows could serve as an analogy for the tiny sodium atoms.

Answer:
In this experiment, different solutions are made by mixing water with different colors and amounts of food coloring. Students should notice that once the water and colors are mixed together, the liquid looks the same throughout. It is a solution—a homogeneous mixture
