A sample burndown chart for a completed iteration. It will show the remaining effort and tasks for each of the 21 work days of the 1-month iteration. A burndown chart or burn-down chart is a graphical representation of work left to do versus time. [1] The outstanding work (or backlog) is often on the vertical axis, with time along the horizontal.

In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature.
A burn down chart tracks work remaining over time while burn up charts like the CFD track the growth (or shrinkage) of work in certain states over time. In agile software development, when teams use kanban methodology, the cumulative flow diagram shows the number of active items in each column on a kanban board.
For example, Mackenzie Investments commissioned a test to gauge the spending and saving behavior of Canadians to determine if they are “Overspenders.” [3] Burn rate is also used in project management to determine the rate at which hours (allocated to a project) are being used, to identify when work is going out of scope, or when ...

Some multistep reactions can also have apparent negative activation energies. For example, the overall rate constant k for a two-step reaction A ⇌ B, B → C is given by k = k 2 K 1, where k 2 is the rate constant of the rate-limiting slow second step and K 1 is the equilibrium constant of the rapid
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
