Answer:
Explanation:
The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
Answer:
Sound needs a medium through which to travel.
Explanation:
In space there is no air or medium. Sound waves need medium to travel. It cannot travel through vacuum. Sounds waves are mechanical waves unlike electromagnetic waves. Electromagnetic waves can travel through vacuum. But mechanical waves such as sound waves needs a medium to propagate the energy. So it is very unlikely that people inside the space station can hear the explosion that occurs in space outside the space station.
The molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.
<h3>Heating of water molecules</h3>
Temperature is defined as a measure of the average kinetic energy of the molecules of a body. The higher the temperature of a body, the higher the kinetic energy of the molecules of the body.
In both systems, we have water molecules that have the same formula H2O. However, the molecules in system #2 have a higher kinetic energy because they are at a higher temperature than molecules in system#1.

The correct answer is the Tyndall effect. This is also known as the Tyndall scattering. It is the light scattering by the particles in a colloid or in a suspension. This phenomenon is used to determine size and density of particles in colloidal matter.
Answer:
8.82 kg es la masa total de leche
Explanation:
Consideraremos que el volumen de cada bolsa de leche es de 900 mL.
Sabiendo que tenemos en total 7 bolsas, el volumen final en litros que tenemos disponible es de:
900 mL . 7 = 6300 mL
Utilizando la densidad podemos calcular la masa de leche que tenemos en el total de las 7 bolsas
Densidad = masa / volumen
Densidad . volumen = masa → 1.4 g/mL . 6300 mL = 8820 g
Convertimos la masa de gramos a kg
8820 g . 1 kg /1000g = 8.82 kg
