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.

Is cellular respiration a negative or positive delta g?
Photosynthesis is a positive delta G as it produces more free energy than it uses. The overall result of the Gibbs equations shows that delta G is positive
What determine whether a reaction took place?
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)
What causes a dipole dipole forces?
Elecronegativity is the ability of an atom to attract the electron density of a covalent bond to itself. Different atoms of elements have different electronegativities. As a result, in a covalent bond, the shared electrons are closer to the atom with the higher electronegativity or 'better pulling power' As a result, the atom with the higher electronegativity is 'slightly more negative' (delta negative dipole) and the other atom is 'slightly more positive' (delta positive dipole). As a result, a delta negative atom of one molecule will be attracted to the delta positive atom of another moleclue, and vice versa. As a result of this, the molecules are attracted to each other, forming dipole-dipole intermolecular forces. Hope this helps :)
Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
What is the full form of your blood groups like o positive b negative?
The groups are: A negative A positive B negative B positive AB negative AB positive O Negative O positive
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
Is cellular respiration a negative or positive delta g?
Photosynthesis is a positive delta G as it produces more free energy than it uses. The overall result of the Gibbs equations shows that delta G is positive
Is the process of KNO3 dissolving in water spontaneous at all temperatures studied?
yes delta s is positive, delta h is negative making delta g negative at all temps
Is CHF2Cl polar or nonpolar?
Polar because of the delta charges on the Cl and F atoms The carbon atom is delta positive, and the Cl and F delta charges are negative.
What are the symbols used to indicate partially positive and partially negative?
In chemistry, Partially positive charge is shown by δ+ Partially negative charge is shown by δ-
What does it mean by positive and negative delta S?
Means a increase or decrease in disorder in the reaction depending on the sign ( "-" or"+")
Is a positive plus a negative make a positive or a negative?
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Does the carbon atom have the delta negative charge in the carbon-chlorine bond?
No, as t is less electronegative it has a partial positive charge.
How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
If a negative is divided by a positive is it negative?
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
