If you heat your melting point tube too quickly, what will your observed melting point be in comparison to the actual melting po
solniwko [45]

Explanation:

When conducting a melting point experiment, if we were to heat a sample quickly. Large amount heat is provided instantly which would melt the crystals in the tube very quickly, even before the temperature of the thermometer reaches to that level. So the observes melting point would be much lower than the actual melting point when sample is heated slowly.

Write a statement that shows how the charge of an ion relates to the number of electrons transferred.
DanielleElmas [232]

Answer:

Q = ne

Explanation:

Ler n be the number of electrons transferred and Q be the charge of an ion.

The net charge on the object is then given by :

Q = ne

Where

e is the electronic charge

Hence, the charge of an ion relates to the number of electrons transferred is equal to Q = ne.

Which statement below is not a premise of the Kinetic-molecular theory of gases?
zhuklara [117]

Answer:

d = all are premise of KMT.

Explanation:

A

Gas particles are extremely small and have relatively large distance between them.

B

Gas particles are continuously moving in random, straight-line motion as they are collide with each other and the container walls.

C

The average kinetic energy of gas particles is proportional to the temperature of gas.

All these are the premise of kinetic molecular theory. According to kinetic molecular theory, the particles pf gases are very small and randomly move in the available space. They move freely in straight line and colloid with each other and also the wall of container. This collision is elastic. As molecules strike with each other and walls of container their energy increases, and they gets warmer. So their kinetic energy is proportional to the temperature because mass of particle is constant.
