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 is delta negative and delta positive?
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.
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 :)
How will temperature affect the spontaneity of a reaction positive delta h and delta s?
∆G = ∆H - T∆S and for it to be spontaneous, ∆G should be negative. If both ∆H and ∆S are positive, in order to get a negative ∆H, the temperature needs to be elevated in order to make the ∆S term greater than the ∆H term. So, I guess the answer would be "the higher the temperature, the more likely will be the spontaneity of the reaction."
What happens when delta h is positive?
the reaction is endothermic
What conditions make delta G always positive?
G is always positive when enthalpy increases and entropy decreases.
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"+")
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.

A chemical reaction that has a positive ΔG is correctly described as?
This is a nonspontaneous reaction, which means that it is reactant-favored. According to the second law of thermodynamics, product-favored reactions must have a negative delta G.It can also be described as an endergonic reaction - that is a chemical reaction in which the standard change in free energy is positive, and energy is absorbed.

What does a negative delta mean?
When tracking the difference of two values over time, what would a negative delta indicate?
Which atom in the carbon-chlorine bond is assigned the delta negative charge?
The Chlorine atom has the delta negative charge because it's more negative than carbon.
