Apart from their habits , bacteria and archea differ in cell wall structure and membrane lipid composition . A ll bacteria have peptidoglycans in the cells wall where as the archea do not . both also are different in the RNA polymerases and thus in their protein synthesis .I hope that can help you !!:))

Answer: The skin lotion is a colloidal mixture of water and various oils.

Explanation:

Mixture: Blend of of two or more components which are chemically unreactive to give any product.

Mixture are defined as of three types:

Solutions : Mixture in which one component is completely distributed in an other component resulting in clear mixture. They cannot be separated into its components on standing or by filtration.

Suspensions: Mixture in which one component is not completely or uniformly distributed in another component.They separate out into layers when kept undisturbed.

Colloids: Mixture in which one component is uniformly distributed in another component but the mixture formed is not clear. The color of mixture appears turbid or cloudy. They cannot get separated by filtration. They also cannot get separated into its components when left standing.

A skin lotion is a fine mixture of water and oils. it is a cloudy mixture and cannot be separated with help of filtration. Also its components also not separates out on standing. All these properties shown by skin lotion is of colloidal mixture.

The ksp for silver sulfate (ag2so4) is 1. 2 ✕ 10-5. Calculate the solubility of silver sulfate in each of the following

Allisa [31]

For ksp of silver sulfate (ag2so4) at 1. 2 ✕ 10-5, the solubility of silver sulfate is mathematically given as

x = 5.26*10^{-4}

<h3>What is the solubility of silver sulfate in 0.15 M AgNO3?</h3>

Generally, the equation for the Chemical reaction is mathematically given as

Ag2SO4 ⇄ 2Ag+ + SO4 2-

Therefore

Ksp = [Ag+ ]2 *[SO4 2-]

1.2*10-5 = ( 0.15 +2x)2*(x)

x = 5.26*10^{-4}

In conclusion, the solubility of silver sulfate is

x = 5.26*10^{-4}
