<span>M(HCl) * </span><span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(<span>NaO<span>H)
</span></span></span>
M(HCl) = 0.35
<span>V(HCl) = 45mL
</span>M(NaOH)= 0.35
now, solne for V(NaOH) by putting these values in the above equation.
M(HCl) * <span>V(HCl) </span>= <span>M(NaOH) * </span><span>V(NaOH)</span>
<span>0.35 * 45 = 0.35 * V(NaOH)</span>
<span>V(NaOH) = 45 mL</span>
What is wrong with the experimental design is that the student changed more than one independent variable.
WHAT AN EXPERIMENT SHOULD CONTAIN?
- An experiment is a procedural method of solving a scientific problem or answering a scientific question. An ideal experiment should contain two variables namely: independent variable and dependent variable.
- Dependent variable: This is the variable that the experimenter measures in the experiment. The dependent variable responds to changes made to the independent variable.
- Independent variable: This is the variable that is manipulated in an experiment in order to bring about a response.
In the experiment conducted by the student in this question in order to determine how the temperature of water affects the time for sugar to dissolve. The independent variable is the DIFFERENT TEMPERATURE OF WATER while the dependent variable is the TIME TAKEN FOR SUGAR TO DISSOLVE.
N.B: An experiment should have only one independent variable and all other variables should be kept constant. This is to have a reliable result.
- However, this student used two independent variables (temperature and amount of water) for the experiment, which is wrong for the experimental design.
Therefore, the fact that the student changed more than one independent variable is wrong for the experimental design.

Answer:
Explanation:
to put this plainly after putting strong electrolytes in water they dissolve to nothing but ions they give you an example and definition of a strong electrolyte I suggest you read those and see if you come up with what I gave you they also tell you that not all strong electrolytes dissolve as strongly as others that are in the example.

lower price and higher voltage capacity for the weight.
Almost all plants and animals go through either photosynthesis or respiration!
