If the relative humidity is high and the temperature drops, water vapor may
meriva

If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases. This is because colder air doesn't require as much moisture to become saturated as warmer air.

Which of the following statement(s) is/are TRUE for the citric acid titration?
RoseWind [281]

Under-titrating means too little indicator was added to the reaction.

TRUE

Since the volume of titrant is too small, multiplying by a small number in the calculation of citric acid makes the mass of citric acid too low.

TRUE

The reaction was stopped too quickly (before reaction was complete).

FALSE

aniked [119]

Answer:

Exotérmica.

Explanation:

¡Hola!

En este caso, dado que la mayoría de reacciones de combustión son exotérmicas, al generar calor en los productos, es posible inferir que esta reacción, referida a la combustion de metano es exotérmica debido a lo anteriormente mencionado, ya que el término de energía de reacción, 531 kcal, está al lado de los productos, lo que quiere decir que es energía generada.

¡Saludos!
