In the soap density demonstration, you know when the soap sinks beneath the surface many times. explain why the soap sink when the mass measured 48g when the mass of the soap measured .1 G.
What is The reason why the soap Did sink was because as you break the surface tension the slope would sink. Page decreases the density of the soap and stays the same.

What is P1V!/T1=P2V2/T2
When an atom is trying to satisfy the octet rule and resides an electron it has what type of ionization energy?
What is negative Ionization energy
what do valence electrons tell us?
they show us the reactivity od an atom.
The pressure of a balloon increases from 14 mmHg To 6mmHg The temperature is held constant at 300K. Move the volume is measured to be 2 L after the pressure decreases. What was the original volume of the balloon?
What is 1L
what does an electron need to do to emit light?
He has to absorb energy and get excited then the element has to fall back down and it emits light.
Solve the density of an unknown substance he finds the volume by adding the solid 40ml of water and. The water now reads 44ml of water the mass is 15g and finds the density of the unknown solid.
what is 120K.

A metal tanker is fully sealed and is shipping gas across state boundaries. The thinker's pressure was recorded to be 500mmHg when departing from the station, but upon arrival, the tankers pressure was measured to be 489mmHg. The mechanic reported the temperature of the gas being shipped on arrival to be 273k. What was the temperature of the gas when it left the station?
What is 307K.
How do Neon lights work?
What has to absorb energy from the electrons in the neon tube, and get excited when the elements had to fall back down and it admits light
