What if a potassium chlorate sample is contaminated with moisture. Would an analysis show the experimental oxygen higher or lower than the theoretical oxygen?
The experimental oxygen would be higher than the theoretical oxygen in a contaminated sample of potassium chlorate. This is because the moisture would contribute to the sample's weight when measured, resulting in a higher oxygen content calculation compared to the theoretical amount based on the chemical formula.
What is the formula to calculate assay?
The formula to calculate assay is: Assay (%) = (Actual quantity of substance / Theoretical quantity of substance) x 100. This formula compares the actual quantity of a substance present in a sample to the theoretical quantity that should be present, expressed as a percentage.
What type of probability uses a knowledge of sample spaces as opposed to experiments to determine the numerical probability that an event will occur?
Theoretical probability.
What is the theoretical percent zinc in a sample of zinc iodide?
The theoretical percent zinc in zinc iodide is 59.92%. This is calculated by dividing the molar mass of zinc by the molar mass of zinc iodide (which includes zinc and iodine) and multiplying by 100.
When is chi-square tests for goodness of fit used?
Chi-Square Goodness-of-fit Test is used when you want to test if the sample observed follows an assumed theoretical distribution.
What is the theoretical limit to the number of factors included in an ANOVA?
The theoretical limit to the number of factors included in an ANOVA is primarily governed by the sample size and the degrees of freedom available. Each additional factor requires additional degrees of freedom for the model, which can lead to overfitting if the sample size is not sufficiently large. Practically, as the number of factors increases, the complexity of the model grows, making it harder to interpret and potentially leading to issues like multicollinearity. Therefore, while there is no strict upper limit, the number of factors should be balanced with the sample size and the research objectives.
What are the modules was implemented in online shopping project?
The modules implemented in the online shopping project include the web framework and the I Shop Order interface. Also, the Sample ShoOrder Item module was used.
Why it is said that number of theoretical plates should be high for a good efficiency?
In liquid chromatography the 'theoretical plates' number is a measure of the resolution between the peaks of different eluting substances. The higher the plate value the greater the separation. This is particular important as the load reaches the maximum the column is designed for.
Would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
The experimental percent oxygen may be lower than the theoretical percent oxygen due to factors such as experimental error, incomplete reactions, or impurities in the sample. Variability in experimental conditions can influence the accuracy of the results obtained.
What if a potassium chlorate sample is contaminated with KCL would the experimental percent oxygen be higher or lower than the theoretical percent oxygen?
If a potassium chlorate sample is contaminated with KCl, the experimental percent oxygen would be lower than the theoretical percent oxygen. This is because KCl does not contain oxygen, so the contamination would dilute the amount of oxygen produced during the decomposition of potassium chlorate.
True or False As the amount of confidence increases the required sample size should decrease Explain your answer?
I can examine this as a question of theory or real life: As a matter of theory, I will rephrase your question as follows: Does theoretical confidence interval of the mean (CI) of a sample, size n become larger as n is reduced? The answer is true. This is established from the sampling distribution of the mean. The sampling distribution is the probability distribution of the mean of a sample, size n. I will also consider the question as a matter of real life: If I take a sample from a population, size 50 and calculate the CI and take a smaller sample, say size 10, will I calculate a larger CI? If I use the standard deviation calculated from the sample, this is not necessarily true. The CI should be larger but I can't say in every case it will belarger. The standard deviation of the sample will vary from sample to sample. I hope this answers your question.
