Answer #1

percentage of yeild= experimental yield/ theoretical yield

theoretical yield is the maximum possible yield. if the percentage of yield greater than 100 means experimental yield > theoretical yield.that is meaningless because theoretical yield is the maximum possible yield.

normally the percent yield is at least a little bit less than 100% due to losses, side reactions, and incomplete reactions.

percentage of yield greater than 100 comes due to

1)undetected impurities in the product.

2) product separation is not good because maybe excess reactant also precipitated along with products

3)product not dried properly.

Q1 - The number of adults (people greater than or equal to 15 years of age) that are considered officially unemployed (by government-calculated statistics) is typically different from (and usually less than) the number of adults actually without a job. This situation may arise because: i) The labor force (as calculated by government statistics) is inclusive only of adults who are either employed or actively seeking employment. ii) Full-time students, homemakers, and retirees are not considered part of the labor...

Medication errors by a nurse happen every day. In fact, adverse drug events account for almost 700,000 ER visits and 100,000 hospitalizations every year. In many cases, these errors can lead to medical malpractice claims made against individual practitioners or even against entire health care teams. The majority of medication errors are preventable, and knowing how they happen can teach you what to be aware as future nurses. These five real-life medication error case studies that involved nurses. While these...

1. Nickel, a common metal used in a variety of alloys, is purified via the Mond process to a very high (> 99.99%) purity. One of the steps in the Mond process involves the reaction of solid nickel with carbon monoxide to produce Ni(CO)4, as shown in the unbalanced equation below. Ni(s) + CO(g) → Ni(CO)4(g) How much carbon monoxide, in grams, is required to purify an impure sample containing 4.22 kg of nickel? (to the correct number of sig...

An experiment on memory was performed, in which 16 subjects were randomly assigned to one of two groups, called "Sentences" or "Intentional". Each subject was given a list of 50 words. Subjects in the "Sentences" group were told to form multiple sentences, each using at least two words from the list, and to keep forming sentences until all the words were used at least once. Subjects in the "Intentional" group were told to spend five minutes memorizing as many of...

Use Python 3.8: Problem Description Many recipes tend to be rather small, producing the fewest number of servings that are really possible with the included ingredients. Sometimes one will want to be able to scale those recipes upwards for serving larger groups. This program's task is to determine how much of each ingredient in a recipe will be required for a target party size. The first inputs to the program will be the recipe itself. Here is an example recipe...
