One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but when we talk about osmosis, only the solvent molecules (water molecules) cross the membrane
I'm not sire which one it is but hope i helped
Petroleum is a mixture of hydrocarbons. Each hydrocarbon consists of carbon and hydrogen atoms. A hydrocarbon contains carbon chain and its boiling and melting points increase with increase in length of the carbon chain. The length of the carbon chain increases with increase in the number of carbon atoms forming bonds. Therefore, the boiling point of hydrocarbon increases with increase in the number of carbon atoms.
(Answer) (2) increase in the number of carbon atoms.
Answer:
It will have a partial positive charge
Explanation:
If a polar molecule has a electronegative side it means it has more electrons on that side, which have a negative charge. So, that means if it is less electronegative it would be more positive than the other side. Hope this makes sense, I'm trying my best to explain but this is how I understand it. :)
Explanation:
For a compound to show hydrogen bonding it is necessary that the hydrogen atom of the compound should be attached to more electronegative atom like fluorine, oxygen or nitrogen.
For example, , and all these compounds contain an electronegative atom attached to hydrogen atom.
Therefore, these pure compounds will exhibit hydrogen bonding.
Thus, we can conclude that out of the given options , and are the pure compounds which will exhibit hydrogen bonding.
Potassium chlorate decomposes to form potassium chloride and oxygen.
Balancefd equation is as follows;
2KClO₃ --> 2KCl + 3O₂
stoichiometry of KClO₃ to O₂ is 2:3
At STP, 1 mol of any gas occupies a volume of 22.4 L.
Number of moles in 22.4 L is - 1 mol
Therefore in 11.2 L - 1/22.4 x 11.2 = 0.5 mol
When 3 mol of O₂ are formed - 2 mol of KClO₃ react
therefore when 0.5 mol of O₂ are formed - 2/3 x 0.5 = 0.33 mol of KClO₃ reacted
Therefore 0.33 mol of KClO₃ are required
the mass of KClO₃ required - 0.33 mol x 122.5 g/mol = 40.43 g
