    Although the term “dysphagia” is often regarded as a symptom or sign‚ it can be used to describe a medical condition in its own right. Many people that suffer from dysphagia are unaware of it – in such cases‚ it may go undiagnosed and untreated. This raises the risk of aspiration pneumonia‚ a serious lung infection that can develop after the accidental inhalation of saliva or food particles. Undiagnosed dysphagia may also lead to dehydration and malnutrition. A physical examination and a variety

    strontium and barium Calcium sulphate is sparingly soluble‚ and you can think of strontium and barium sulphates as being insoluble. That means that you will get a layer of insoluble sulphate on all of these which will slow down the reaction or stop it entirely. In the calcium case‚ you will get some hydrogen produced together with a white precipitate of calcium sulphate. -------------------------------------------------------------------------------- Note: With strontium and barium‚ I have

    solubility rules my results proved accurate. Just by looking at the solubility rules‚ my results were what I expected them to be. I found that sodium chloride did not react with any of the five substances and that the sodium sulfate only reacted with the barium nitrate. The sodium bicarbonate‚ sodium carbonate as well as the sodium hydroxide reacted with all five substances. This was expected because the solubility rules stated that these were all insoluble substances. I was careful to add exactly two drops

    Hydrogen Peroxide & Inorganic Peroxy Compounds Hydrogen Peroxide Hydrogen peroxide (H2O2) is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Hydrogen peroxide is a clear liquid‚ slightly more viscous than water. In dilute solution‚ it appears colorless.  Reactions Decomposition Hydrogen peroxide decomposes exothermically into water and oxygen gas spontaneously: 2 H2O2 → 2 H2O + O2 This process is thermodynamically favorable. It has
