One external factor that could affect a child’s development is poverty and deprivation. This splits into 5 categories; diet‚ housing‚ education‚ play & leisure opportunities and aspirations & expectations. If a child is born into a family of low-income‚ the 5 categories above tend to be negatively affected due to a lack of money and opportunities. A poor diet‚ for example‚ can mean that children are fed an unhealthy diet of processed food‚ meaning they are not as healthy and they are unlikely to

ACID RAIN Cantarelli‚ Ilaria García Díaz‚ Bianca Gressier‚ Emilie Martínez Rivas‚ Carmen What’s the acid rain? Acid rain is a rain or any other form of precipitaton that is unusually acidic. What causes acid rain? Acid rain is caused by the burning of fossil fuels. Burning oil‚ gas and coal in power statons releases Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere. These gases mix with water droplets in the atmosphere creatng

Experiment C. Aim: To protect one of two carbonyl groups (C1) in order to allow the other to react twice with a Grignard followed by removal of the protecting group by acid hydrolysis to give final product (C2). Method: Ethyl acetoacetate (30.03g)‚ ethylene glycol (15.01g) and toluene-p-sulphonic acid (0.13g) were added to a 250 cm3 round bottomed flask‚ containing a stirrer bar and toluene (100 cm3)‚ fitted with a condenser and dean-stark head. Solution was heated strongly under reflux using

The third part Section C 5-25% of sodium chloride was prepared by the instructor. For each percent concentration of sodium chloride a 25 mL was prepared. Weighing the graduated cylinder before and after the sodium chloride was transferred the density were calculation. Pre- Laboratory Questions: 1.

Honors February 14th‚ 2014 ACID RAIN 1. Acid rain is rainfall created by pollution in the atmosphere. When the rainfall occurs‚ it almost always causes harm to the environment. 2. Acid rain is caused by the release of certain compounds into the air‚ including sulfur dioxide and nitrogen oxides. These compounds mix and react with chemicals such as oxygen and water and form acid rain. 3. Acid rain can harm the environment by acidifying lakes and streams‚ which greatly affects the water life. It also

was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid diluted in distilled water and mixing it with HCl using a reflux set-up. A reflex set up is a distillation set up wherein the set up differed because it is inverted vertically. This was done in order to break the pi bond to allow the rotation about the remaining sigma bond since rotation about a pi bond is not possible. After the acid has been refluxed‚ a white

Investigating the effects of acid rain in the growth of cress seedlings IntroductionAcid rain is rain or any other form of precipitation‚ which is unusually acidic. It has harmful effects on plants‚ animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react in the atmosphere to produce acids. Acid rain can slow the growth of vulnerable forests and cause leaves and needles to turn brown and fall off. In addition‚ it depletes minerals from the
