Question: Suppose you started with 200 dice. Use the correct empirically determined formula and determine many rolls would it take to end up with 100 dice remaining.
Equation: N=NO exp (kj*i) where No is the original number of dice, N=100, Kj constant is -0.166 ± 0.01 and i is the number of rolls.

Using confidence intervals to determine how many samples you’ll need to collect so the average voltage will be within the desired accuracy. This will take some assumptions and some work. So, here goes: The confidence interval (CI) equation is: Assume that the voltage you are measuring has a true mean (of course we don’t know the actual mean or true value, but that’s OK) of approximately 1 volt. Next, suppose you desire to know your average () vs “true” value...

Review | Constants Periodic Table In the parts that follow, use the following abbreviations for time If a substance is radioactive, this means that the nucleus is unstable and will therefore decay by any number of processes (alpha decay, beta decay, etc.). The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions: Measure of...

Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...
