interesting questions scientist ask why does this chemical reaction happen when you mix this stuff together . Why do baking soda and vinegar react with each other? This happens because of an acid base reaction and also because baking soda is a bicarbonate and vinegar is an acid and when you mix them together fiss start to show up . What does this have to do with my science fair project? This has to do with my science fair project because it shows how the volcanic eruption shows in my paper mache

soon after spraying. This may irritate a person’s throat‚ and lungs. So the researchers decided to find an organic‚ health-friendly‚ and effective fire extinguisher‚ and found out that banana peels contain tartaric acid‚ which when added to sodium bicarbonate and water‚ produces carbon dioxide that removes oxygen from a fire‚ causing the fire to decrease and stop. STATEMENT OF THE PROBLEM This study will be conducted primarily to test the potential of Saba banana (Musa balbisiana) peels extracts

Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate?

measured using a styrofoam calorimeter. The three reaction are shown below. Reaction 1: The dissolving of solid sodium hydroxide in water. NaOH(s) ---> Na+(aq) + OH-(aq) + heat Reaction 2: The reaction of solid sodium hydroxide with dilute hydrochloric acid. NaOH(s) + H+(aq) + Cl-(aq) ---> Na+(aq) + Cl-(aq) + H2O Reaction 3: The reaction of sodium hydroxide solution with dilute hydrochloric acid solution. Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) --->

Abstract. This report is about how to standardize a Sodium Hydroxide (NaOH) solution by titrating it with pure sample of Potassium acid Phthalate (KHC8H4O4). This experiment has two sections. The first section is to standardize the Sodium Hydroxide by titration. Three sample of 0.7 – 0.9 g of solid KHP are place into each of the three numbered Erlenmeyer flasks. 50 ml of distilled water are added to each three of it from graduated cylinder and constantly shake it until the KHP solution are completely

which extinguishes specific type of fire. Class A contains pressurized water & is used on fires with paper‚ cloth‚ & wood. Class B contains carbon dioxide & is used on fire with gasoline‚ oil‚ paint‚ & cooking fat fires. Class C contains potassium bicarbonate or potassium chloride‚ is used on electrical fires because the chemical is non conducting agent‚ also used on burning liquids for a smothering action. Class ABC or combination is the most common at homes or schools. It contains a graphite type chemical

Also known as "benzoate of soda‚" sodium benzoate is an FDA-approved‚ polyunsaturated fat that has been used by food manufacturers for over 80 years to inhibit microbial growth. As a food additive it is used as a preservative‚ effectively killing most yeasts‚ bacteria and fungi. Sodium benzoate is effective only in acidic conditions (pH < 3.6) making its use most prevalent in foods such as preserves‚ salad dressings (vinegar)‚ carbonated drinks (carbonic acid)‚ jams (citric acid)‚ fruit juices (citric

quickly. One chemical that is made industrially is sodium thiosulfate. Sodium thiosulfate solution is sold in a range of concentrations. Dilute solutions of sodium thiosulfate can be used for cleaning contact lenses and used as a medicine for some cancer patients. Concentrated solutions are used to treat spillages of some chemicals. Sodium thiosulfate is safe to handle and store‚ but if it is mixed with an acid‚ a reaction happens. When dilute sodium thiosulfate is mixed with an acid‚ solid sulphur
