investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they have a good

MİGRANT MOTHER AND LA FAMİLİA Art has always been important to society. The art influence and modify to society and which is formed society’s understanding and era. Especially visual arts such as paintings and photographs all important for know better. For example: Jaime Olaya’s painting La Familia and Dorthea Lange’s photograph Migrant Mother. l am going to compare and contrast the similarities and differences between Migrant Mother and La Familia. There are some similarities between the two

EFFECT OF CHANGES IN TEMPERATURE AND SDS CONCENTRATION ON THE STRUCTURE OF BEETROOT CELL MEMBRANES. Introduction Cellular Membranes or cell membranes are biological membranes that separate the interior of a cell from the outside environment. Cell membranes are selectively permeable to ions and some molecules and control the movement of substances in and out of the cell. (Danyk‚ 2013/14) Cell membranes separate and organize chemicals and reactions within cells by allowing selective passage

Investigating the Effect of Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work

Testing the effect of concentration on rate of reaction Plan: We are investigating the effect of nitric acid on calcium carbonate. We are doing this experiment‚ as we would like to understand the effect that acid rain has on limestone. We also want to understand how acid can have an effect on rate of reaction. The word equation for the reaction that will take place is: Calcium Carbonate + Nitric Acid Calcium Nitrate + Carbon Dioxide + Water The balanced symbol equation

The Keto Diet Trap • What is keto diet? The ketogenic diet ensures that kind of diet that is saturated in high-fat. This is actually the low – carbohydrate food that has plenty of proteins in it. This diet concept is very popular in these days just because of the fact that people are very conscious about their health and this low- carb diet is an assurance for them to make them healthy in the near feature keeping them healthy. Normally‚ the food carbohydrates transform itself into glucose to transport

Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Method 1- Titration • For the titration‚ it is necessary to dilute the Sodium Hydroxide so that it is an easier concentration to titrate. Using a 25cm3 pipette‚ washed out with some of the NaOH solution‚ transfer 25cm3 of the solution to a 250 cm3 volumetric flask‚ and fill to the line with distilled water. The alkali will now have a concentration of 0.1 mol dm-3. • In the titration‚ the NaOH will be in the burette‚ and will be titrated into HCl in a conical flask: NaOH (aq) + HCl (aq) NaCl
