In this experiment, the molecular weight of a condensed vapor was found through a procedure using an unknown liquid. The flask before adding the unknown liquid in was full of air. After the beaker full of water started to boil the flask was examined until the unknown liquid was completely vaporized. At that exact point the flask contained all vapor. At the final weighing the flask contained condensed vapor and air. There is always a chance for error. Some sources of error could have come with completing this lab over an open water bath and some water vapor may have been in place. Also, too much vapor could have escaped and the experiment might not have been stopped quick…

Procedure: I used various different tools to investigate the different physical and chemical properties, such as blue and red litmus papers, beakers, and wells.…
Arsenic damages any life forms it has contaminated. Most animals, fish, bacteria, and birds will die when they come into contact with arsenic. Plants cannot properly photosynthesize.…
The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred.…
2. Figure 13.6a eventually moves into the air. The conversion of a liquid to a gas or vapor is called vaporization. When such a conversion occurs at the surface of a liquid that is not boiling, the process is called evaporation. Most of the molecules in a liquid don’t have enough kinetic energy to overcome the attractive forces and escape into the gaseous state. During evaporation, only those molecules with a certain minimum kinetic energy can escape from the surface of the liquid. Even some of the particles that do escacape collide with molecules in the air and rebound into the liquid.…
In solids, the molecules are vibrating due to little space. "Heat is a measure of the average molecular motion of matter." (Convection, Conduction, and Radiation). Heat is transferred from one object or matter to another by three types of methods: convection, conduction, and radiation. "Conduction is heat transfer by direct molecular interactions, without mass movement of matter" (Convection, Conduction, and Radiation). "Convection is heat transfer by mass movement" (Convection). "When molecules of a liquid vaporize, they escape from the liquid into the atmosphere" (Evaporation). This is the definition of evaporation. Radiation are Electromagnetic waves that directly transport ENERGY through…
Andy Warhol constructed the painting ‘32 Campbell’s Soup Cans’ in early 1962. Alongside the exclusive frames all placed flush relative to each other. Additionally, each enclosed structure is approximately 20 inches by 16 inches. Piece by piece, the Campbell’s Soup Cans Andy individually painted received a different assortment of flavor, the top left corner coordinates with a tomato soup can thoroughly to the bottom right corner ending with turkey vegetable soup. Correspondingly, the series of Campbell’s soup cans exposes each type of soup. Andy painted the cans from an elevated front facing view. Provided that, two dented metal rings define the top portion of the bare metal can. The top half of each Campbell’s Soup can is colored red, while the bottom half of the can is a plain white color. Each word printed on the label on the can is in a different font. The word ‘Campbell’s’ illustrated in large white cursive. Underneath the Campbell’s word, but still on the top red portion of the can designed in a capital bold text reading ‘CONDENSED’. Between the bottom and top of the can is a brown circle representing the distinct stamp of the Campbell’s Company. Andy Warhol painted the circle, but left out the details within the brown stamp. In addition, the white bottom half of the can represents the type of soup written in a…
In this experiment the ideal gas law will be utilized to solve for the number of moles of vapor while other conditions are equilibrated with a boiling water bath. By measuring the mass of that vapor the molar mass can be calculated.…
An example of this would be the melting of ice and boiling of water. When an ice cube melts it turns into water and when the water is boiled it turns into steam or vapor. As one can see an ice cube, water, and steam have extremely different physical properties. Ice cubes are solids, water is a liquid, and steam is a gas.…
On heating a liquid, some of the particles will gain sufficient energy to allow them to break away and become a gas. A gas expands to fill its container that is, it does not have a definite size nor volume, neither does it have a definite shape. Gases always spread out to occupy all the space available to them. Gases are very easily expanded or compressed. Tgeir particles are randomly arranged with very large spaces and weak forces between them. Of the three(3) states of matter, the particles if a gas move the fastest and have the largest amount of energy.…
