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?

The rates of chemical reactions in industry are carefully controlled because ‘Time is money!’ So it is important that chemists can make reactions happen and make useful products as quickly as possible. However‚ sometimes chemists deliberately slow down reactions to avoid health and safety risks. Some reactions can go out of control and lead to large amounts of toxic or flammable gases being made too quickly. One chemical that is made industrially is sodium thiosulfate.

Clostridium Difficile People getting medical care can catch serious infections called healthcare-associated infections or HAI’s. One type of HAI which is caused by the germ Clostridium Difficile or C-Diff. In 2015 it was estimated almost half a million infections in the United Ststes‚ and 29‚000 died within 30 days of the initial diagnosis. Those most at risk are older adults‚ who take antibiotics and also get medical care. The CDC provides guidelines and tools for the healthcare population to help

Similar to potassium‚ sodium is a major mineral‚ however‚ unlike potassium which maintains fluid and electrolyte balance inside the cell‚ sodium is a major part of the body’s fluid and electrolyte balance system because it is the chief ion used to maintain the volume of fluid outside cells. Sodium also helps maintain acid-base balance and is essential to muscle contraction and nerve transmission. The DRI recommended intakes for sodium for adults ages 19 to 50 years old is 1‚500 milligrams per day

Lithium‚Sodium‚Potassium‚Rubidium‚Caesium and Francium are all part of group 1.They are metals that can be easily cut.After being cut‚it is shiny but it quickly tarnishes due to the fact that the metal reacts quickly with oxygen or water.The shiny surfaces of Sodium quickly tarnishes more quickly than Lithium and Potassium more tarnishes more quickly than Lithium.This shows that the reactivity increases as we move down the group.

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

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1.

Sodium borohydride Reduction of Benzil Introduction: The Purpose of this experiment is for the students to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols‚ and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product‚ the metal hydride nucleophile of the reducing agents such as LiH‚ LiAlH4
