Experiment 18 A Factors Affecting Reaction Rate Bob Jones Josh October 2‚ 2014 Period 3 Introduction: In reference to the collision theory‚ molecules act as small spheres that collide and bounce off each other‚ transferring energy among themselves when the collide. In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include

The Montessori Classroom uses the phonics approach to teach reading. Outline the graded phonics sequence and state the reading skills required at each stage. Language is the origin of human civilization. Humans’ capability to express and to communicate an idea by means of speech and words lead the human race to greater discoveries. Building a word by combining sounds and building a sentence which represents an idea by combining words‚ then integrating sounds into symbols and presenting in a written

times and record the force the kinetic and static friction for each trial. After part 2‚ it is also necessary to determine the force of static and kinetic friction for the other surfaces that come with the lab kit‚ which are the mirrored and sandpaper surfaces. Try using the blocks provided with at least two flat surfaces around the home to understand the concepts learned in the previous parts of this lab‚ such as carpet‚ rubber‚ tile‚ or anything similar. Record your results in the tables similar

Introduction In this chemical reaction‚ the magnesium will dissolve in the hydrochloric acid to produce hydrogen gas. This is because magnesium is higher than hydrogen in the reactivity series. Therefore‚ when the two reactants are combined‚ a displacement reaction occus and the magnesium displaces the hydrogen‚ forming magnesium chloride and hydrogen gas. Mg (s) + 2HCl (aq) -> MgCl 2 (aq) + H 2 (g) Magnesium + Hydrochloric acid -> Magnesium Chloride + Hydrogen

E1: Reggio Emilia In 1945‚ Loris Malaguzzi founded the first Reggio school. His Reggio education dominated the Italian education that was already in place. The approach of Reggio is community led‚ this involves everyone in their close community but also those from outside of the close community. Within Reggio‚ they repeat their ideas and activities‚ so that the children are able to revisit what they were doing the day before to further their understanding of what they were doing‚ but also get help

CHEMICAL REACTION (SYNTHESIS REACTION‚ DECOMPOSITION AND SINGLE REAPLACEMENT REACTION) Purpose : 1. To identify the chemical changes 2. To observe the effect of temperature of a chemical reaction. Theoritical basic : A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Classically‚ chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds between

The mashed potatoes were like eating oatmeal with strands of sandpaper glued onto each bite. The dish was an atrocity‚ and it should never be served again until the chefs learn to grill a steak

weight always‚ without fail‚ creates a greater force of friction. 6. An increase in weight does not affect the coefficient of friction by also increasing it‚ although theoretically it shouldn’t affect it at all because myu is constant. 7. If sandpaper were glued to the bottom of the block then‚ the coefficient of friction would increase because its a different surface and also because the force of friction is increasing. 8. One way to decrease the friction is to lubricate the block and table
