    Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate

    shareholder’s equity. And each side had to balance each other out. Next we had to invest $25‚000 for business supplies. This will fall as a debit and credit line item under assets because we spend cash and the $25‚000 would increase the value of the business. Next we had to but the land for $150‚000. This was a debit and credit line item under assets because we used cash and credit $100‚000 under liability because we now owe a debt. After fully balancing the equation‚ we had $200‚ 00 in assets

    High School Students’ Conceptions about Energy in Chemical Reactions (focusing only in exothermic and endothermic reactions). Aim The aim of this study is to investigate students’ understanding of the energy concept in chemical reactions particularly in endothermic-exothermic reactions. Both qualitative and quantitative methodology was used for this investigation. A twenty-item multiple choice test was developed about the topic to measure the students’ understandings. This concept test was

    There are many different ingredients in a kitchen that causes a chemical reaction with baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct

    Differential Equations Second Order Differential Equations Introduction In the previous chapter we looked at first order differential equations. In this chapter we will move on to second order differential equations. Just as we did in the last chapter we will look at some special cases of second order differential equations that we can solve. Unlike the previous chapter however‚ we are going to have to be even more restrictive as to the kinds of differential equations that we’ll look at
