WebThe fats and oils formed are also known as triglycerides. Like other esters, fats and oils are formed by a reversible reaction. Oils (liquids at room temperature) contain more carbon to carbon double bonds than fats (solid at room temperature). The lower melting point of oils is related to the higher degree of unsaturation. Web1. A hand warmer contains sodium acetate, dissolved in water. The solution is ‘super-saturated’, which means it has been heated to dissolve more sodium acetate. The solution crystallises readily. 2. When the internal metal strip is bent, tiny bits of metal are released, which offer ‘nucleation sites’ for crystals to form. 3.
WebRedox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Some examples of common redox … WebThe reaction rate increases in the direction of less gaseous molecules and decreases in the reverse direction. Thus, it can be understood that pressure and concentration are interlinked and that they both affect the rate of reaction. How …
