The defendants cannot argue that the normal person would not suffer the injury incurred by the plaintiffs because he must take the victim as he finds him according to eggshell skull rule. The eggshell skull rule also has been extended to eggshell personality. This rule is applied in the case of Malcolm v Broadhurst. The defendant negligent’s driving had caused injuries to the plaintiff and the husband. Due to the accident‚ the plaintiff’s husband’s personality

Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the percentage mass of calcium carbonate in

Background of the Study Fruits peels of Banana‚ Orange and other fruits are highly rich in potassium‚ ion‚ zinc etc .If these Peel are added in the soil these will become fertilizers. Fertilizers are any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of the plant. Good fertility is fundamental to successful plant growth and the application of fertilizers and manures is an essential graining act

Chapter I Introduction A.) Background of the Study: The Acids‚ bases and salts in the pH range are among the most important chemical compounds used by chemists. For instance‚ hydrochloric‚ phosphoric and citric are acids used to make mineral stain removers‚ toilet bowl cleaners‚ metal cleaners and rust removers. A variety of maintenance chemicals contain these compounds. Alkali maintenance chemicals like degreasers‚ oven cleaners and drain openers contain bases such as Sodium Hydroxide (NaOH)
