Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

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

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?

Old Dominion University ORGANIC 214 Alkene Addition Submitted by: Alkene addition: Bromination of (E) Stilbene Introduction: In this lab we used the greener approach‚ which involves the addition of bromine across a double bond. When bromine reacts with E-stilbene (trans-1‚2-diphenylethene)‚ two new chiral carbons are created from the sp2 carbons‚ therefore 3 different dibrominated stereoisomers are possible: meso-(1R‚2S)‚ or the raceminc mixture-(1R‚2R) or (1S‚2S)-dibromo-1‚2-diphenylethane

INTRODUCTION Sodium hypochlorite is considered one of the most efficient irrigant in endodontics 1-4. Due to its antimicrobial‚ tissue dissolving properties and low cost‚ it is one of the most widely accepted irrigant in Endodontic practice 5-8. Sodium hypochlorite as a solution is relatively an unstable compound. On exposure to organic compounds‚ heat‚ light‚ air and metals‚ the available chlorine ions reduce and there is subsequent loss of tissue dissolving and antimicrobial properties 9-10. Recent
