Question 3 (2 points)
Stress was added to the following reaction and this was the result:

As4O6 + 6C <-> As4 + 6CO

The equilibrium shifted to the right and the reverse reaction decreased.

Select all factors that would have caused this observation.

Question 3 options:

CO was added to the system

As4 was added to the system

As4 was removed from the system

As4O6 was removed

Question 4 (1 point)
If CO2 was added to this system what would the outcomes for this reaction be?

CO2 + H2O <-> H2CO3

Question 4 options:

It would shift to the right, favor the forward reaction and the rate of reaction would decrease.

It would shift to the left, favor the forward reaction and the rate of reaction would increase.

It would shift to the right, favor the forward reaction and the rate of reaction would increase.

It would shift to the left, favor the reverse reaction and the rate of reaction would decrease.

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
