The scientific method is a series of sequential steps used to build scientific knowledge. In the scientific method, the collection of data is a previous step before making conclusions from these data.
- The statement 'Collecting research data is the final step in the scientific method' is FALSE.
The steps of the scientific method include:
- to make one particular observation of some aspect of the natural world in order to formulate one question from such observation
- to propose a possible explanation (hypothesis) in order to explain this question
- to test the hypothesis by collecting experimental and/or observational data
- to examine the collected data in order to accept or reject the working hypothesis
- to make a conclusion from the results

We suggest starting to prep for the the SAT as early as eighth grade year. It sound early, but if a student plans on taking the SAT several times throughout high school, eighth graders can take a relaxed and long-view approach to prepping, and can plan on taking their first SAT sophomore year.
The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.
<h3>What is pH?</h3>
The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.
The first step to determine the pH of the HF solution is to set up the ICE table as shown;
HF + H2O ⇄ H3O^+ + F^-
I
C
E
The values of the initial concentration of HF as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;
Ka = [H3O^+] [ F^-]/[HF] Knowing that [H3O^+] = [ F^-] = x
