According to Denman: Increasing size of uterus Greater pressure on blood vessels Regurgitation of blood to cerebral vessels Cerebral congestion convulsions A PICTURE OF Dr. THOMAS DENMAN In 1849 Dr. William Tyler Smith challenged this theory because he believed that pregnancy was a state of fullness in circulation and many cases of Convulsions would be observed if such congestion caused convulsions. According to him‚ the cause are; • Any excessive mechanical

Scrubber systems In short a scrubber system basically removes harmful materials from exhaust gases before they are released into the environment or atmosphere. There are two types of scrubbing methods. There is wet and dry scrubbing. Both systems work in similar ways and have the same end result. That is to change a toxic chemical into something less toxic or non-toxic. Now scrubber systems rely on a chemical reaction with a sorbent (which is a material that sorbs another substance or A substance

considered a health concern. There are two types of Hardness: Temporary hardness: this is due to the presence of bicorbonates of calcium and magnesium. It can be easily removed by boiling. Permanent hardness: this is due to the presence of chlorides & sulphate of calcium & magnesium. This type of hardness cannot be removed by boiling. MOTIVATION I was bothered that the water in Ilara community doesn’t combine easily with soap leading to excessive consumption of WATER.

make. Most sponges are made mostly of cellulose‚ which is known for being the most common organic compound on earth. The process starts when cellulose fibers‚ sodium sulphate crystals‚ hemp fibers‚ and dye are mixed in a tumble drum. Then‚ they are cut into rectangular shapes and are cooked. What this does‚ is melt the sodium sulphate crystals‚ and leaves little holes in the cellulose. After that‚ the sponge goes through a cleaning process to make it suitable for the market. Lastly‚ the sponges are

The protein reacts with copper sulphate in alkaline solution to give a deep purple color with an absorption maximum at 550 nm. The sodium hydroxide solution is added to it to create alkaline conditions. Procedure: 1. Label the five test tubes on the rack; fill each 2cm3 of the liquids. 2. Then fill each will an equal amount of sodium hydroxide. 3. Add copper (II) sulphate drop-by-drop and note chances if any. Ethanol emulsion test The ethanol

Protein Essay- Erin Keegan What are proteins? A polypeptide is a chain of monomers joined up to make a polymer. Proteins are organic polypeptides made up of a chain of amino acid residues- they’re residues because they lose a water molecule. The amino acids (monomers) join up by forming peptide bonds. When two amino acids join together‚ they become a dipeptide. This happens when the carboxyl group of an amino acid and the amino group of another amino acid link up through a condensation reaction (which

5 mol H2SO4 + 2KOH HCl + KOH K2SO 4 + 2H2O; KCl + H2 O Now‚ 5 mol of H2SO 4 require KOH = 2.5 mol Total KOH required = 10 + 2.5 = 12.5 mol. Question 2 Two acids H2SO4 and H3PO4 are neutralized separately by the same amount of an alkali when sulphate and dihydrogen orthophosphate are formed respectively. Find the ratio of masses of H2SO4 and H3PO4 [at mass P = 31] Ans. H2SO4 + 2NaOH Na 2SO4 + 2H2O H3PO4 + NaOH NaH2PO4 + H2O Equivalent of alkali = 1 g equivalent of H2SO4 = 1 g equivalent
