These are just a few of the possible Addition that can occur across the double bond

- The C-H bonds in this structure are shown at 1444 and 1368cm-1. These two bands indicate the two different types of C-H bends that occur on the molecule. One is that of the alkene and the other is that of the several alkanes on the molecule.

We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL.

To prepare a quantitative solution, you need to know the weight of the substance and the quantity of the solution. For example, you have 40 grams of NaOH (Sodium Oxide) in 1000mL of water. The amount of water and weight of the substance makes a Mole. one mole is equal to 1000mL of water and 40 grams of NaOH and varies by the amount of water you have but the weight of the substance must also change. To make a correct solution, you need to know the atomic mass of the substance and how much water you have in mL or L. If there are multiple elements, you need to add the combined weight of all elements (EX. NaOH= 23+16+1+40 grams.) and then divide the weight by the mass. To make a solution, you should use a beaker or flask that can measure at least

If 10.0g of solid baking soda is poured into 30 mL of citric acid, then a reaction will occur and an increase in temperature will be observed. Whereas, if a piece of magnesium metal is added to 30 mL of Hydrochloric Acid, then a reaction will occur and an increase in temperature will be observable. For Part 3 of the experiment, if 50 mL of tap water is placed in a can 2.5 cm inches above a burning marshmallow, then through the process of calorimetry the energy content of the marshmallow should be 5.0kJ/g (the value provided by the United States Department of Agriculture).

In part I, the ΔH of each individual reaction was obtained by performing each reaction inside a calorimeter. Temperature probes were inserted in the calorimeter and ΔT was measured. By using the equation q = Msol’n x Cp x ΔT + Ccal x ΔT, the heat absorbed by the surroundings, q, was obtained for each reaction. The negatives of these values, or heat released by the

The yield of following reactions for methane is related to the temperature and the amount of natural gas. The mass balance for free carbon and hydrogen is mentioned as

The 1952 Schlitz advertisement that is shocking to most modern day feminists, was trying to normalize the “imperfect woman” by advertising beer. The printed ad states: “Don’t worry darling, you didn’t burn the beer!” After WWII, women were slowly gaining independence as most of the male population was away at war. The women had to fill in the spots of males in society, transcending from the private sphere, being confined to the home, to the public sphere, where they would work for wages. Once the men returned home from war, so did the women. The women became confined to their homes and became what we know as the stereotypical housewife: caretakers of their children, caterers to their husbands, and makers of the home. The media continued to build upon the ideas of the perfect housewife, and while perfect housewives were ubiquitously depicted in their ads, they strategically used women as bait to conform to the development of the dramatic consumerist ideologies.

There are many forms of energy. The types of energy that can affect the toy car are potential energy, kinetic energy, and work of friction. Potential is the energy of an object due to its position. Kinetic energy is the energy due to motion. Friction plays a part because it shows how much energy is needed for the car to move. All these energies are intertwined in the toy car.

6 x C-H (412) + 2 x C-O (360) + 3 x O-H (463) + 3 x O=O (498)  4 x C=O (805) + 8 x H-O (463)

Well we all know that the energy system is very unstable because the total energy available on the earth is limited, and man has exploited all the conventional technologies to fulfill his needs. By the use of these conventional technologies, the world also has a disability, with problems such as global warming. Consumption of energy by man increased gradually as his wants also increase. The conventional energy resources mainly include fossil fuels, but research shows that this fuel source will be depleted completely in approximately 20-25 years. This could cause major setbacks around the world. As a result, we need an alternative source of fuel that could keep the world running on its wheel. One possibility is ethanol. Chemically extract

The aim of this experiment was to test the heat of combustion over a period of time, and the energy required to combust alcohols with different carbon chain levels. It was hypothesised that the higher the carbon chain of the alcohol present, the faster the heat of combustion will occur. Meaning more energy will be released for a higher carbon chain. After calculating the results from the experiment it was found that the hypothesis was partially supported. The reasoning for this is as the alcohol that posses a higher carbon chain, generally increased there reaction rates. However there were a few exceptions to this rule.

drop one of them and it was to shatter, you must not pick it up
