What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
When you divided a negative number by a positive number witth the answer be positive or negative?
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
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 spontaneity of a reaction is determined by the sign of the Gibbs free energy (ΔG). If both enthalpy (H) and entropy (S) are positive, the reaction can be spontaneous at high temperatures where the TΔS term outweighs the positive ΔH term, resulting in a negative ΔG. This means the reaction will be spontaneous at elevated temperatures.
Can an O positive parent have a b negative child?
It is possible (by spontaneous mutation, for example) but unlikely.
A chemical reaction has a positive ΔH value and a positive ΔS value Under what conditions is the reaction spontaneous?
The reaction will be spontaneous at high temperatures (T) where TΔS > ΔH, according to Gibbs free energy equation, ΔG = ΔH - TΔS. At high enough temperatures, the TΔS term can outweigh the positive ΔH term, leading to a negative ΔG value and a spontaneous reaction.
Is impetuous a positive word?
"Impetuous" can be seen as either positive or negative, depending on the context. It can describe someone who is passionate, spontaneous, or daring, but it can also suggest recklessness or impulsivity.
Is free energy of cell reaction positive when emf of cell reaction is positive?
No, the free energy of a cell reaction is negative when the emf of the cell reaction is positive. This is because a positive emf indicates that the reaction is spontaneous and capable of performing work, resulting in a negative change in free energy.
How is temperature affect the spontaneity of a reaction with positive H and S?
An increase in temperature generally makes reactions with positive enthalpy (ΔH) and positive entropy (ΔS) values more spontaneous. This is because at higher temperatures, the increase in the TΔS term can outweigh the positive ΔH term in the Gibbs free energy equation (ΔG = ΔH - TΔS), resulting in a more negative ΔG and thus a more spontaneous reaction.
Predict whether the changes in enthalpy entropy and free energy will be positive or negative for the freezing of water and explain your predictions How does temperature affect the spontaneity?
The changes in enthalpy, entropy, and free energy are negative for the freezing of water since energy is released as heat during the process. At lower temperatures, the freezing of water is more spontaneous as the negative change in enthalpy dominates over the positive change in entropy, making the overall change in free energy negative and leading to a spontaneous process.
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
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
