In your chemistry class, your instructor fills three different flasks with three different gases. She tells you that one gas is

carbon dioxide (CO2), one is oxygen (O2), and one is simply the mixture of the gases in the atmosphere (air).
She removes the stopper from each flask and quickly performs a splint test as shown in this video. You notice that the ember continues burning in the first flask, it reignites but does not blow itself out or pop in the second flask, and it is completely extinguished in the third flask.

Which gas was in each flask?
air
oxygen
carbon dioxide
Drag the name of each gas to the correct flask.

Where is the epicenter of this hypothetical earthquake?
Zolol [24]

Answer:

In fact, the epicenter of a hypothetical earthquake is located at the point where the earthquake begins to break. The epicenter is just above the surface of 'our planet'. The epicenter is what we call immediately above the 'hypocenter' of the earthquake on the stage that said surface.

melisa1 [442]

Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.

Explanation :

Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.

_Z^A\textrm{X}+_{-1}^0\textrm{e}\rightarrow _{Z-1}^A\textrm{Y}

The equation for the given reaction is,

_{19}^{40}\textrm{K}+_{-1}^0\textrm{e}\rightarrow _{18}^{40}\textrm{Ar}

Thus, the chemical symbol for the element that results from this process is, argon (Ar).

unsaturated solution

2)equilibrium phase change

Heat of vaporization

condensation

heat of fusion

normal boiling point

vapor pressure

3) equilibrium reaction

saturated solution

Ksp

solubility

Ka

Explanation:

Nonequilibrium processes are those processes that are irreversible. They often lead to an increase in entropy of the system.

In chemical systems, a state of equilibrium is said to have been attained when the rate of the forward process equals the rate of the reverse process. This is true for both chemical reaction and phase changes. A state of equilibrium connotes a constancy in physical properties of a system over a period of time.
