Acetyl chloride‚ CH3COCl‚ also known as ethanoyl chloride or acyl chloride‚ is an acid chloride derived from acetic acid. It belongs to the class of organic compounds called acyl halides. It is a colorless liquid. Acetyl chloride does not exist in nature‚ because contact with water would hydrolyze it into acetic acid and hydrogen chloride. In fact‚ if handled in open air it gives off white smoke owing to the hydrolysis from the moisture in the air. The "smoke" is actually small droplets of hydrochloric

Name _____________________ Class ______________ Date _________ Addition and Resolution of Vectors Equilibrium of a Particle Overview When a set of forces act on an object in such a way that the lines of action of the forces pass through a common point‚ the forces are described as concurrent forces. When these forces lie in the same geometric plane‚ the forces are also described as coplanar forces. A single G G equivalent force known as the resultant force FR may replace a set of concurrent forces

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries

Sexual Addition may be a common problem but it still remains a relatively understood condition characterized by strong sexual urges. In recent weeks‚ the issue has resurfaced. Last week‚ a Journalist Brian Alexander(2007)‚ this psychological condition was once again questioned and the condition was described as such: "Sexual addiction is defined as any sexually-related‚ compulsive behavior which interferes with normal living and causes severe stress on family‚ friends‚ loved ones and one’s work

Signed_________________________________________ Abstract A common road salt‚ magnesium chloride‚ was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a deicer. To determine the Van’t Hoff factor‚ the difference of temperatures of freezing water and a solution of magnesium chloride was determined. A Van’t Hoff factor average of 2.88 was found‚ which

is a relationship between addition and multiplication. When you are multiplying you are simply adding the same number several times. For example 2*3 is the same as adding 2 three times‚ 2*3=6 which is the same as 2+2+2=6. Understanding the relationship between addition and multiplication contributes to the understanding of these concepts to the student because the student will be able to grasp the concept with more ease since they should have been experts in addition once they start learning multiplication

In this lab experiment‚ we used sodium bicarbonate to influence photosynthesis. Sodium bicarbonate is a formula of NaHCO3 (baking soda). In this lab experiment‚ we observed photosynthesis in spinach leave and investigated the effect of sodium bicarbonate on photosynthesis. The experiment was to determine how many disks of spinach leaves float at the end of every ten minutes. Our main focused and question was how using different amount of concentration of sodium bicarbonate would affect the process
