Entire Review Problems Cumulative- Practice 1. At a certain car wash‚ 40 more cars than vans go through on a typical day. If each car pays $12 and each van pays $16 and the total earned per day is $2244‚ find the number of vans that go through the wash. 2. a) In the Fine Company‚ the CEO must invest in 30% more shares than the CFO. The shares sell for $10.20 each and the total value of the shares owned by the two of them is $132 549. Find the number of shares owned by the CEO.

in a Compound CHEM 1315-022 For experiment one‚ The Determination of the Percent of Water in a Compound‚ the sole purpose of conducting this experiment was to determine the percent of water found in compounds such as Magnesium Sulfate‚ Copper Sulfate‚ and so on. Along with determining the percentages of the hygroscopic compounds the experiment allowed for the exploration of separation of hydrogen bonds to ionic solids through the use of heat. The reason that the water clings to the ionic compounds

EXPERIMENT 6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid)‚ a phenol (p-tert-butylphenol)‚ and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent‚ the solution that contains these dissolved compounds is called an extract (Manion

Identifying Organic Compounds Problem: Based on the color of the indicator‚ which type of organic compound will be found in each type of food? Hypothesis: If Benedict solution is added to honey‚ then it will turn. If Biuret solution is added to egg whites‚ then it will turn. If Benedict solution is added to corn oil‚ then it will turn. If Benedict solution is added to glucose‚ then it will turn. If Benedict solution is added to gelatin‚ then it will turn. If Benedict solution is added to butter

St.‚ Intramuros‚ Manila Melting Point and Boiling Point of Organic Compounds Group No. 5 Manacup‚ Cris Vincent L. Oblena‚ Adrian D. Ong‚ Joshua Jyro B.* *Leader ABSTRACT In compounds‚ two of the physical properties affected by the varying structures are melting point and boiling point. Through the use of the Thomas-Hoover Melting Point Apparatus or the micro method‚ the melting and boiling point of organic compounds are now determined. The aim of this experiment is to know the factors

Compare and contrast the structure and bonding in Ionic‚ Covalent and Metallic species. Relate the structure and bonding to the properties of the species. Ionic bonding is usually formed between a metal and a non-metal‚ Covalent between two non-metals and Metallic between two metals. Ionic Bonding; Ionic bonds tend to form between metals whose atoms need to “loose” electrons to gain the nearest noble gas configuration and non-metals that need to gain electrons. These electrons are transferred
