Thermochemistry
What is the specific heat of platinum if 1092 J of heat were released into a calorimeter when it was cooled by 65.2 C
A 185 g sample of copper at 98.0 C was added to 102 g of water at 20.0 C in a calorimeter. The final temperature of the copper-water mixture was 31.2C. Calculate the specific heat of copper using this data.
How much heat in kJ is required to raise the temperature of 250.0 g of Hg 52.0 C? the heat capacity of Hg is 0.14 J/gC.
The molar heat of combustion of a compound is 1250 kJ/mole. If 0.115 moles of this compound in a bomb calorimeter with 2.50 L of water, what would the temperature increase be?
If change in heat is positive it is an _______ reaction
If change in heat is negative it is an_______ reaction
Use the following data to find the energy change in J of each system

Stoichiometry Lab Report

930 Words | 4 Pages

In order to begin this experiment, first one must find the balanced chemical equation for the reaction which occurs between the aluminum and copper (II) chloride. This balanced equation being 2Al(s)+3CuCl2 (aq)3Cu(s)+2AlCl3 (aq). After finding this equation, one must use the process of stoichiometry in order to find how many grams of aluminum are needed in order to produce 0.15 grams of copper. In this experiment, the purpose was to produce between 0.1 and 0.2 grams of copper, so one should attempt to produce 0.15 grams of copper seeing as it is the average of those two numbers. The first step in the stoichiometric process which one has to complete is finding how many grams of copper are in one mole of copper.

When the students placed the wire containing the sample in the flame it burned a orange/ red color. when this result was compared with the previous flame tests it could have resulted from either CaCl2 or NaCl. Both of these compounds produced an orange flame. After the flame test was conducted, the students performed a litmus test to identify whether the unknown was neutral or a base. When exposed to the red and blue litmus paper, no reaction occurred.

5. Public trials and executions serve as a deterance of deviant behaviors. These sanctions act as a way to set an example and for people to see what will happen to them if they do the same thing, These sanctions can also be seen as reinforcing boundaries. Although public executions and trials in “town square” are not as common in most countries today, the media is utilized to fulfil the same purpose. When there are high profile cases going on in the United States often tmes the full trial and sentancings are televised so that much of society can see what the repercussions are for defying a social norm.

Stoichiometry Lab

563 Words | 3 Pages

Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.

This means that all of the elements in the same group have a main aspect in common, except for a few exceptions. These elements react with the same specific compounds. This was used to identify the order of the groups from left to right and to determine which elements go under which group. Some research was conducted to identify all the names of the groups ranging from element number one to element number 20. Once all group names were recorded, it was researched which groups react with which compounds that are given on the element cards.

Another way to calculate the enthalpy of neutralization is to assume the density of the solution to be equal to the density of water in order to assume the mass of the solution. 1.00 g 〖cm〗^(-3)×50 cm^3±0.96 %= 50.00 g ±0.96 % The heat released can then be calculated using the assumed mass. q=50.00 g±0.96 % ×4.18 J g^(-1)

Health Care Parameters

1839 Words | 8 Pages

Abstract— As the population is increasing worldwide, a huge need arises to provide proper health-care services. India is such a country, where the population keeps on rising every year and the government is not able to provide basic health care check-ups due to lack of a number of doctors in the country. The research focuses on measuring basic health parameters like pulse rate and body temperature using a microcontroller and develop an android app for appointment of doctor. In conventional system, patients have to physically wait in queues in order to get the appointment. The main objective of this paper is to reduce the time for the appointment and to increase the number of patients per day by doctor, as we know doctors per 1000 person is
