Molecular Formulas

The body later was identified as Juan Antonio Guerra-Torres. Sheriff Deputies discovered that his body had been shot several times and then his head was decapitated and his limbs had been dismembered and that it appeared that this all appeared as post-mortem.

Empirical formulas represent the ratio of atoms in a formula. It is expressed in the simplest, small, whole number ratio. The molecular formula can either be the empirical formula, or a multiple of the empirical

An empirical formula must have a whole number ratio of atoms in each element. The ratio is multiplied by two.

The Empirical Formula is a formula that shows elements in a compound. The molecular formula gives the amount of atoms that each element has in a compound. These formulas were used to calculate and find elements that were given prior to the crash. The formulas also helped our team find out which passengers had each of the possible materials on the flight.

A full police operation yielded no solid evidence, and Ramirez repeated his attack pattern on the couple, William and Lillie Doi in April 1985. Over the next two month period Ramirez's murder rate increased rapidly, killing another dozen victims in a frenzy of burglary, assault and

32. An empirical formula is the simplest mole ratio among the elements in a compound.

After retrieving files and records containing information about her fan club and boutiques, and as Selena and Chris left the hotel, Selena came to the conclusion that Saldivar kept a few of the files. So she got up early in the morning pretending to go jogging. She took chris's red pick up truck and drove to the texas motel yolanda was staying. Selena and Saldivar argued over Saldivar holding records still to the point where Selena said that they could not be friends at that time and nor could they work together. She took the ring the "Saldivar" got for her and was about to place it on the bed when Saldivar pulled out the .38-Caliber Taurus Revolver and shot Selena once in the right shoulder as Selena ran for her life, severing an artery. Yolanda was angry that they couldn't even be friends

The crime that was committed by Ivan Milat left many Australian’s horrified. Ivan Milat, born and raised in Guildford, Australia in 1944. He was born into a large Yugoslav family in outback Australia. Between the years of 1990 and 1996, seven people were found murdered in the Belanglo State Forest in NSW. The victims were all backpackers who were visiting Australia.

This section will dealt with the main organic molecules in living things: carbohydrates, fats ( lipids ), proteins and nucleic acids.

In John’s text messages, Brandy texted she would “kill him”. Brandy does have a car and she also has a pet cat. Moving on, suspect two was Sergio Jones, a CCA student and the victim’s lab partner. Sergio had no clear motive to murder John, he was at the library until 8:00pm that night. Sergio does not have a car, but he does have a dog.

But soon people started to realize her talent, and she was getting record deals, and was beginning to start a career. They hired a new guitarist named Chris Pérez. Chris and Selena began to have feelings for each other, and eventually became a couple. They hid it from Selena’s father, assuming he would try to break them up. When he did find out, he was very angry and made Chris get off of their bus. Selena and Chris’s relationship still continued in secret, and thinking it would make her father leave their relationship alone, they went and got married. Selena's father heard about it on the news, and became angry. But eventually when Selena came home, they talked and he was all right with

The first suspect was James W. Lewis. He was a con-artist and his handwriting was found to match the two letters to the white house as treats. The first letter sent was threatening the white house to continue the poisonings and the second was also threatening the white house that he was going to bomb it. The only problem about this suspect was that he was in New York for about 27 days before the murders. This is a problem because the cyanide which was the poison used would have eaten throughout the capsules. The poison would have been needed to be planted up to a day before the murders. Some people think he got a ticket from New York to Chicago then got a taxi planted the fake pills in the bottles then got another ticket and got out of there.

Maria was obviously murdered. She was lying facedown with a bullet wound present at the left lower-part of her skull.. A quick look revealed the following clues: a .32 caliber bullet lodged in the ground in front of her nose, and a bullet casing lying to the left of her feet.. “Hmm,” he thought, “fired from close range due to the powder burns.” He checked the bullet casing for fingerprints, but didn’t find

The guiding question of this ADI lab was, “What are the identities of the unknown compounds?” The goal of this lab was to understand the relationships between moles and molar mass to find the identity of unknown compounds. The mole can be used to measure small amounts of a substance or is used to convert from unit to unit using dimensional analysis. One mole is equivalent to the molar mass in grams of that substance. If you start with the moles of an unknown substance, multiply it by a given compound’s molar mass, and then divide it by however many moles are in the compound of your choice, you will get the mass of the compound. With that answer you can then compare with mass of the compound in the bag to determine its identity. We first started

The answer to the question of “What is the empirical formula of this substance containing zinc and chlorine?” Simply put, the answer is ZnCl2. This is what the empirical formula is because when the mass of each substance is converted into number of atoms, the ratio of Zinc to Chlorine is about 2:1 for almost every trial conducted. See Figure 1. Equations 1 and 2 demonstrate how the conversions were performed and how moles/ molecular weights of each substance were incorporated in the calculations.
