Have any good ideas for a Science Fair Project relating to Celiac Disease?
I have had Celiac Disease for almost 5 years now and it has been my goal for the last five years to educate more and more people on the importance of Celiac Disease. For my Science Fair Project I would like to do something involving Celiac or the Gluten Free diet that all Celiac patients are on. I would prefer something towards Celiac but for now, I am desperate for any ideas since I have already raided Google looking for ideas. Thanks in advance(:
What are acid and basic radicals?
Acid radical is substance left out without hydrogen which is generally a non metal or anion.See an example HCl if we separate this two we will get H+ and Cl- this Cl- is our acid radical.And basic radical is substance left out without a hydroxide ion which is generally a metal or cation.See an example NaOH if we disassociate them we will get Na+and OH- here Na+ is the basic radical .And salt is formed always of this basic and acidic radical.Ex - NaCl.
Can a gas diffuse in a gas?how about a gas in a liquid?give example?
diffusion is the movement of paricle from a region of higher conc. to a region of lower conc. therefore a gas can diffuse in a gas if either one is conc. in one point and the same goes for gas in liquid example: u can smell the fart of someone else even though he's sitting at the other end. that's because his fart diffused into the air you breathe in.
What are the different types of indicators in chemistry?
Chemical indicators are typically colorless when contained in a bottle by itself, but when the indicator is added to a solution, the pH of that solution can make it express a color. It helps determine the pH of a solution, much like pH test strips; chemical indicators can, however, be added to a solution before an acid or base is added and when the solution changes color, you know you’ve added enough of the extra base/acid to reach the desired pH.Below, you can see the name of the indicator, its pH range, and the color it expresses at different levels of acidity and basicity.
How do I test the acidity of different tea leaves in a chemistry lab?
The question you have asked reminds me of my grade 10 igcse chemistry question. (TITRATION METHOD)-First take tea leaves you wanna test (Take equal mass/ number of them)-Crush them and dissolve in water. -Add an indicator such as methyl orange or phenolphthalein- Use a burette to pour any base (NaOH, etc)-Add the volume of base required to completely neutralize any acid. This time the colour of the acid-indicator solution will permanently change.-Measure this volume this will give the volume of acid inside-Repeat with all leaves -Check which was take most NaOH is the most acidic.
What are some examples of acids used in everyday life?
Hydrochloric acid: It is produced in our stomach to help with digestion.Acetic acid: When vine becomes vinegar, its alcohol is oxidized to acetic acid.Citric acid: The sour taste of lemon juice is citric acid.Carbonic acid: The carbon dioxide in carbonated drinks doesn’t totally remain in a dissolved condition, a part of it forms with water carbonic acid, hence the ‘tickling’ taste.DNA: Those initials stand for Deoxyribo-Nucleic Acid.Edit (as suggested by Mr Ian Friskus):We should not forget the other genetic information carrier:RNA: Ribo-Nucleic Acid.Nitric acid: The so called ‘Nitrogen cycle’ (schematically shown below), without which life as we know it would not be possible, goes through nitric acid.Sulfuric acid: We don’t much use sulfuric acid directly in daily life, except as the acid in Lead-Acid car batteries.Still, sulfuric acid takes part directly or indirectly in the manufacturing of practically everything, so that its annual world production is about 230 million tonnes.By their names alone, for example, you would not think that the widely used fertilizers Calcium Dihydrogenphosphate and Ammonium Phosphate have anything to do with sulfuric acid, but, by far the largest amount of sulfuric acid is used to make:Phosphoric acid: The use of huge amounts of phosphoric fertilizers, which are made from phosphoric acid, justifies its inclusion in the acids which ‘are in daily life’.
