Water vapor

a. The solubility of primary alcohols in water compared to that of alkanes. Explain the difference in terms of intermolecular forces. Solubility of alcohols in water Small alcohols are completely soluble in water; mixing the two in any proportion generates a single solution. However, solubility decreases as the length of the hydrocarbon chain in the alcohol increases. At four carbon atoms and beyond, the decrease in solubility is noticeable; a two-layered substance may appear in a test tube when…

Wisconsin. Although this product is mainly water, other main ingredients include ethanol and isopropyl alcohol. According to Hazard.com, hazards identification for Windex includes a list explaining adverse effects of ingestion or overexposure. Windex should not be inhaled or ingested. It may cause moderate irritation if it’s in contact with an individual’s skin for too long. If Windex gets in a person’s eyes, he or she should immediately flush with water for at least 20 minutes and if skin is…

Purpose: The main purpose behind this experiment is to know the how the strength of the intermolecular forces changes with the molecular size and structures. Based on the examination of the evaporation of different liquids and by determining the vapor pressure of different alcohols at a different temperature. Producer: There will be two parts in this experiment to know the strength of the intermolecular forces of different liquids, to conclude the role of the molecular size and structure of…

much like our heart, water gives us power. In the world of water politics, water is power, meant both literally and figuratively. In fact, water is the basis of many things currently. It is the source of our own nutritional benefit and without it we would perish. It is the substance granting life to many organisms of non-human descent. It is the reason for our rainy days and our snowy winters, our pools on hot summer days and the dew fall on the grass on chilly mornings. Water symbolizes job…

Identification of a Liquid Objective This experiment was performed out to determine the identity of an unknown liquid sample by investigating its solubility in water, hexane and ethyl alcohol. Also, its density and boiling point were obtained and compared to the theoretical values. Theory Chemical substances can be identified through investigation of their chemical and physical properties and then comparing the experimental values to the standard values. Physical properties do not change the…

separation technique, in which a feed mixture of different components is separated into two or more reaction products by collecting the overhead distillate, formed as vapor or a mix of vapor and liquid, and keeping the remaining liquid solution in the reaction container. To achieve this: firstly, the feed has to contain a liquid or a mix of vapor-liquid mixture at the start of the reaction. Secondly, These different components in the feed mixture require to have different volatilities, so they…

ratio of water in copper, and magnesium, which is obtained through burning the vapor using the Bunsen burner. Materials: Because the experiments were conducted online there wasn’t any use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs. Procedures: Experiment 1 1. Obtain the mass of an empty 250ml beaker using the balance. 2. 200mls of silver nitrate was added to the beaker,…

referred to as climate change. This increase in heat alters water cycles, effecting significant changes in the availability of fresh water. In addition, abnormal temperatures can disrupt the variety of plants and animals in ecosystems as well as weaken agricultural productivity. As a catalyst for climate change, overpopulation contributes to this increase…

(Hammer & Price, 2001, p. 401). * Water is the commonest extinguishants with some limitations. Overall, water is low in cost, simple to use, and effective. More water may be needed depending on the mixture and temperature. (Hammer & Price, 2001, p. 402). * Gas extinguishants is more effective than water in enclosed spaces. Examples are carbon dioxide, nitrogen, and halogenated hydrocarbons. (Hammer & Price, 2001, p.…

that the visioning has to be sustainable, coherent, tangible, plausible, motivational and capable of achieving a good complexity-capacity balance. a) Sustainable vision – My vision is to BAN Fracking all together. Fracking contaminates underground water and also quite significantly contributes to global warming. In order for these potential dangers to be mitigated, fracking must be banned. It might sound radical but no amount of creating sustainable alternative methods for hydraulic…
