Answer:
See explanation below
Explanation:
The melting point (the temperature that it changes from solid to liquid) of a pure substance depends on its mass, the forces between its molecules, and the pressure of the system.
The melting point, or the freezing point, of a mixture, is a temperature between the melting point of its components. Salt has a huge negative melting point, so when it is added to the water, the melting point decreases from 0ºC to -21ºC approximately.
So, the water will only freeze again if the temperature becomes below -21ºC which is very difficult to happen.
Answer:
your at the sun
Explanation:
it's very hot and super dense
Average kinetic molecular energy is actually defined by temperature, so any gas, no matter the volume or pressure, will have the same average kinetic molecular energy as long as its temperature is the same. Therefore, Gases A, B, and D all have the same average molecular kinetic energy, since they are at 12<span>°C.</span>
Answer:
3
Explanation:
To balance the equation, you need the same number of each atom on both the left and right sides of the equation.
The balanced equation would be:
2 Fe + 3 S ---> Fe2S3
You then have:
2 Fe on both sides
3 S on both sides
