Refer to the balanced equation. (PLEASE HELP QUICK)
kolezko [41]

Answer: C) 5.12\times 10^1 L Cl_2

Explanation: 8H_2S+8Cl_2\rightarrow S_8+16HCl

According to Avogadro's law, 1 mole of every gas occupies 22.4 Liters at STP.

Thus from the balanced chemical equation, 8 moles of hydrogen sulfide reacts with 8 moles of chlorine gas.

i.e 8 moles of hydrogen sulfide reacts with =8\times 22.4L=179.2L of chlorine gas.

2.28  moles of hydrogen sulfide reacts with =\frac{179.2}{8}\times 2.28=51.2L=5.12\times 10^1L of chlorine gas.

The given potentials are observed for a calomel electrode: E ° = 0.268 V and E ( saturated KCl ) = 0.241 V . Use this informatio
Anvisha [2.4K]

Answer: The E for Silver-silver Chloride electrode = 0.287 V

Explanation:

Silver/Silver Chloride (Ag/AgCl) with a value for E° that is actually +0.222 V or approximately 0.23 V has the actual potential of the half-cell prepared in this way as +0.197 V vs SHE, (Standard Hydrogen Electrode) which arises because in addition to KCl, there is the contribuion of AgCl to the chloride activity, which isn't exactly unity.

Therefore, the E for the Ag/AgCl electrode would approximately equal 0.287 V

Describe the difference between a ball-and-stick model and a space-filling model of a compound.
Lisa [10]
A space-filling model shows the relative amount of space each atom takes up. In other words, a space-filling model can show relative sizes of atoms. However, unlike ball-and-stick or structural models, space-filling models do not show bond lengths clearly. Bonds are not really like sticks in a ball-and-stick model.
