For known amounts of reactants‚ theoretical amounts of product can be calculated in a chemical process. These calculated products are determined using the limiting reagent‚ (the substance that runs out first which stops the reaction) and are called the theoretical yield. The theoretical yield is the amount of product that should be acquired during the experiment if all aspects go perfectly. However‚ due to experimental errors‚ very few labs do so. These results are called actual yield. The percent

Five key factors make up your FICO score‚ which is also known as your credit score: your payment history‚ any outstanding debts‚ the length of your credit history‚ the number of inquiries‚ and the types of accounts held. Each of these elements is given a different weight in the calculations that determine your FICO score. Your payment history comprises 35% of the score‚ your outstanding debt is 30%‚ your credit history age makes up 15%‚ and both the number of inquiries and account types are 10% of

QUESTION 4 Explain how the formula for markup based on cost could be used to calculate cost‚ selling price‚ dollar markup‚ and percent markup. Pick a company and explain why it would mark up the goods based on cost rather than on selling price.

Dendrochronology: Determining Reference Ecosystems and the Historical Range of Variability Each and every year‚ trees record information within their growing rings and dendrochronology is the study of these tree-rings. Although tree-ring analysis is limited by the spatial scale of the climates where trees can grow and the temporal scale of the oldest possible age of a tree in a study area (183636 years ago)‚ it has proven to be a crucial tool in paleoclimatology and paleoecology. “To understand

Purpose Using a calorimeter‚ the experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained
