What does a positive and a neagive equal?
positive and a positive is a positive negative and a negative is a positive to answer your question: positive and a negative is a negative.
What is a negative multiplied by a negative?
negative*negative=positive negative/positive=negative negative\negative=positve negative-positive=change the sign to a plus and then change the number after the sign and get your answer negative +positive=which ever numbr is bigger minus positive+positive=positive
A chemical reaction has a positive H value and a positive S value Under what conditions is the reaction spontaneous?
the reaction is always spontaneous :) youre welcome =D i just took this on apex, the correct answer is the reaction is spontaneous only at high temperatures.
Can an O positive parent have a b negative child?
It is possible (by spontaneous mutation, for example) but unlikely.
What happens when a salt undergoes hydrolysis?
when a salt dissolves in water, more positive than negative ions are released
What can be said about a reaction with H 620 kJmol and S -0.46 kJ molK?
it can never be spontanious
According to the Gibbs free energy equation G H - TS when is a reaction always spontaneous?
when H is negative and S is positive
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
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
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
Do non-metals become positive or negative as ions?
It is possible to make positive ions of nonmetals e.g. oxygen, chlorine, by putting enough energy into them. They normally form negative ions when in a spontaneous reaction.
How is temperature affect the spontaneity of a reaction with positive H and S?
∆G = ∆H - T∆S and ∆G has to be negative for the reaction to be spontaneous. So, ultimately the effect of temperature will depend on the value of ∆H. If ∆H is negative, and ∆S is positive, then temperature won't matter, and reaction will be spontaneous. If ∆H is positive, and ∆S is positive, then a high temperature will favor spontaneity. If ∆H is negative and ∆S is negative, then a low temperature will favor spontaneity. So, the answer to your question is the higher the temperature the more likely the reaction will occur spontaneously.
If a negative is divided by a positive is it negative?
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
