Could you please help me format this question, I've been stuck on it for some time now.

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing.  It is important to consider what the experts say, but to also evaluate their statements.  We will start with the scientific method.  I want you to outline the scientific method from what you have been taught in previous classes.  You can list steps, parts, process, short descriptions, whatever.  If not taught in previous classes, then you will make your best guess about it.

In the following sub-questions, use your book and notes to generate an argument for each model of light. Remember, on the first day of class we discussed that argumentation requires: ● a claim (which I've given), • evidence (which you should look up in the form of data or scientific principles) and reasoning that connects the evidence to the claim (which you should generate from your understanding so far).

In the titration of 25.00 mL of a water sample, it took 19.090 mL of 3.165x 10-3 M EDTA solution to reach the endpoint. Calculate the number of moles of EDTA required to titrate the water sample. (enter your answer with 3 significant figures) 6.04x10-5 You are correct. Your receipt no. is 151-9969 ? Previous Tries The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample titrated. (enter your answer with 3 significant figures) 6.04x10-5 You are…
