Answer:

Gas

Explanation:

Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion. For the first Ionization energy, it is the energy needed to remove the most loosely bound electron from a gaseous atom

what is the molecular formula of a compound with an empiricla formula of ch and a molecular mass of 78
Dovator [93]

Answer:

C6H6

Explanation:

We can obtain the molecular formula from the empirical formula.

What we need do here is:

(CH)n = 78

The n shows the multiples of both element present in the actual compound. It can be seen that carbon and hydrogen have the same element ratio here. We then use the atomic masses of both elements to get the value of n. The atomic mass of carbon is 12 a.m.u while the atomic mass of hydrogen is 1 a.m.u

(1 + 12)n = 78

13n = 78

n = 78/13 = 6

The molecular formula is

(CH)n = (CH)6 = C6H6

15 POINTS PLS HELP!!!!!
scZoUnD [109]

Answer: (C) Vaporizing

Explanation:

 Vaporization is the process in which the substance change the state of of liquid into the gas state.

The vaporization process require the largest input of the energy as when the state is in the solid state then, the solid substances contain the strong forces of the attraction and they require high energy to break these strong bonds.

For changing the liquid state into the gases state we require to overcome the surface tension and require enough energy for acquiring the vaporization state.

Therefore, option (C) is correct.

Which of the following would be the best object for stirring hot liquids? (1 point)
MakcuM [25]
A Wooden Spoon is your answer because metal attracts heat more, so it would get hotter.

The wooden spoon would not, so you would use that.

Glad I could help, and good luck!
