In liquids the molecular force isn’t great so they don’t hold toghether as effectively but still,have force to hold together.They slide last each other unlike gases which have no force at all and go in all sorts of directions

seraphim [82]

Answer:

The change in POP can not be reversed hence it is a chemical change.

Explanation:

Plaster of Paris (POP) is used to immobilize a fractured bone. The POP sets when water is added to it, it hardens irreversibly. Once it hardens, its shape can not be changed by any physical means. This means that the hardening of POP is a chemical change.

The chemical name of plaster of Paris is calcium sulfate hemihydrate. The setting of POP is an example of a chemical reaction.

Would you expect an organic compound to be soluble in water why
RSB [31]

Answer: All organic compound depends on  H-bonding with water. more stronger H-bonding with water more will be soluble.

Explanation:

1. It depends primarily upon the function groups of that compound. It also depends on the size of the compound.  

2. some organic compound which soluble in water for example: alcohols, ethers, carboxylic acids.  Because of the functional groups attached to the organic structure (the C-H backbone) are what effect the solubilities.Like carboxylic acids and alcohols form hydrogen bonds with the water, helping to solubilize it.  

3. Take alcohols for example: methanol, ethanol, and isopropanol are all completely soluble in water. By the time you get to butanol and some of the larger alcohols, including those with more complex structures, they tend to be less soluble.

Describe how a chemist should set up his or her stoichiometric calculation to predict the mass of CuSO4 that forms when a specif
DanielleElmas [232]
1) Calculate the number of moles of Cu SO4 . 5H20 by dividing the specified mass by the molar mass.

2) The ratio of production given by the equation is 1 mol of Cu SO4 . 5 H2O to 1 mol of Cu SO4=> 1:1, meaning that the number of moles of Cu SO4 produced is the same number of moles of Cu SO4.5H20 heated.

3) Finally mutiply the number of moles of Cu SO4 by its molar mass and there you have the mass of Cu SO4 produced.
