If the reaction occurs at constant volume at 300K and the reaction obeys first order with respect to A and if A reduces to half its initial amount in 69.3 sec, then calculate 1) heat released when 2*10-3 mole of A has reacted at 300K(in cal)2) rate at which heat is released ...
Customer retention rate can also be used to track customer reaction to changes in the service. For example, you could divide your customers into two cohorts. One cohort gets a major update to the app, while the other keeps using the old version. By comparing the retention rates of the two...
Most experiments are designed to be more advanced than the simple experiment type. These experiments often involve conducting several trial runs, which means more than one experimental value is recorded. During these types of experiments, taking the average of the recorded results is understood to be...
When we think of the great inventors and scientists of the past, it's easy to imagine them tinkering away in their lab or poring over their diagrams until their skilled deductions finally result in them hitting the jackpot. However, with many of the most significant inventions of recent centu...
A horizontal tangent line is a mathematical feature on a graph, located where a function's derivative is zero. This is because, by definition, the derivative gives the slope of the tangent line. Horizontal lines have a slope of zero. Therefore, when the
If you've ever stowed a chocolate bar in your pocket, only to realize later that it has melted, you likely didn't share the same reaction as Percy Spencer did in 1945. Spencer was working with magnetrons, asource of microwaves, while in the middle of a radar project. Noticing that his...
If your teacher has asked you to find the cubic feet of a circle, it might be a trick question. "Cubic feet" is a clue that you're working in three dimensions, which means you're actually looking for the volume of a sphere.

How to Calculate Gross Floor Area. Gross floor area is the total amount of floor space in a building, usually one used for business. It is important to know the gross floor area for many reasons, such as acquiring building permits, determining rent and a
