which derive from environment friendly materials and can easily found in the community. The potential of Averrhoa Bilimbi also known as Kamias for it’s fruit as a solution that can be easily be found in the community.The focus of making these dishwashing liquid is on the effectiveness of this plant as an effective antibacterial agent. In the Philippines‚ the leaves of bilimbi tree are used as a treatment relief for skin itches‚ swellings of mumps and rheumatism. It can also be a good alternative

Chapter 1: Introduction Chapter 1: Introduction Ionic liquids (ILs) can be viewed as a new and remarkable class of solvent. They are also a type of materials that have a long and useful history‚ where the earliest material that meets the current definition of IL was observed in the mid-19th century when a separate liquid phase called the “red oil” was observed in Friedel-Crafts reaction [17]. Over the following years‚ there has been a rapid growing of interest in ILs due to the realization

is to compare the different densities of different liquids. Density is a comparison between an object’s mass and volume. Density = Mass divided by Volume. If the weight (or mass) of something increases but the volume stays the same‚ the density has to go up. If the mass decreases but the volume stays the same‚ the density has to go down. This experiment will show how the weight of certain liquids react to each other. Page 3 The seven liquids I have chosen for the experiment have different weights

a way pf separating mixtures of solids‚ or solids and liquids with different sized particles - The mixture is poured through a sieve and the particles smaller than the sieve pass through while the larger particles are trapped by the sieve - The are commonly used for cooking - E.g. a mixture of rice and water is poured through a sieve to capture rice and remove the water Filtration - Is a technique commonly used for mixtures of solids and liquid‚ particularly when solids particles are quite small and

According to the kinetic theory‚ both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another‚ as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers. Figure 13.5 Both liquids and gases can flow. The liquid on the left is colored water. The gas on the right is bromine vapor. If a gas is

Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids and liquids‚ if the measurements that we did are been accurate and how we can calculate the percentage errors. materials 3 different metals A) copper B) iron C) aluminum - 3 Different liquids A) Water B) Olive oil C) Alcohol - Balance
