Diagram C shows a balanced chemical equation because it has equal number of atoms on both sides of the equation.
Independent variable: weather condition
dependent variable: sales of lemonade drink
controlled variable: the lemonade drink mixture.
Explanation:
From the description of the problem, the independent variable is the weather condition whereas the sales of lemonade drink is the dependent variable.
A dependent variable is one in which relies on the outcome of another variable. The independent variable does not rely on other variable. It is usually the cause in an experiment.
- The weather condition is an independent variable. Maria and Jane are simply trying to project their sales(dependent variable) on the condition of the weather.
- A control is that variable that does not have effect on the experiment. It is usually not the subject of an investigation and has no effect on the outcome. The Lemonade mix of lemon, sugar and water has no effect.

Given what we know, we can confirm that hair gel is considered a noncrystalline solid due to Atoms in the hair gel having no particular order or pattern.
<h3>What is a noncrystalline solid?</h3>
- This is a solid whose atoms are amorphous.
- What this means is that the atoms lack a specific order like most solids.
- The most common example of this is glass.
Therefore, given the definition of a noncrystalline solid as a solid whose atoms lack a specified order, we can confirm that the second option which states that "Atoms in the hair gel having no particular order or pattern" is correct.
