When tracking the difference of two values over time, what would a negative delta indicate?
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
Yes, the mean can be negative if the numbers being averaged are negative. For example, if you are averaging temperatures and all of the temperatures are below zero, your average temperature will be a negative number.
It means that it is an incorrect statement. Vectors can be negative.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
It can have either a negative or positive trend
When tracking the difference of two values over time, what would a negative delta indicate?
it means that heat is released during the reaction and a + delta H means that heat is required/absorbed.
Means a increase or decrease in disorder in the reaction depending on the sign ( "-" or"+")
The Chlorine atom has the delta negative charge because it's more negative than carbon.
The Chlorine atom has the delta negative charge because it's more negative than carbon.
yes delta s is positive, delta h is negative making delta g negative at all temps
yes
When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative. Hope this helps :)
pollution
Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative. A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive. If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)

delta is used in differential calculus as well as other places to indicate a very small amount. Taking water as an example, the oxygen carries a very samll charge and the hydrogens a small positive charge even though the molecule is covalently bonded. The small charge on the hydrogen (as opposed to a full positive charge) is called delta popsitive) and thus the charge on the oxygen is delta negative or more strictly 2 delta negative.
