Negative * positive = negative Positive * positive = positive Negative * negative = positive
Negative * positive = negative Positive * positive = positive Negative * negative = positive
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.
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.
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
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
In thermochemical calculations, a common sign convention is that energy absorbed by a system is positive (endothermic process) and energy released by a system is negative (exothermic process). This convention helps in determining the direction of energy flow and whether a reaction is absorbing or releasing energy.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
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
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
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.
Negatives and Positives Positive + Positive = Positive Negative + Negative = Positive Negative + Positive = Negative Positive + Negative = Negative
a negative x a negative= a positive, a positive x a positive= a positive, a negative x a positive= a negative, and a positive x a negative= a negative. Same thing with division. a negative divided by a negative= a positive, a positive divided by a positive= a positive, a negative divided by a positive= a negative, and a positive divided by a negative is a negative. U see?
