|
|
How many grams of H2SO4 would be found in 4 litres of 0.5M solution?
|
196grams
|
|
|
How many osmols in 4 litres of 4M NaCl?
|
32 osmols
|
|
|
Why does adding salt to water allow it to get hotter before boiling?
|
You increase calligative properties by adding NaCl to the water. More molecules increase the boiling point temperature
|
|
|
What determines the water soluability of a covalent compound?
|
ability to hydrogen bond
|
|

|
1)KBr
2)CaC12 3)BaSO4 4)A12(SO4)3 |
|
|
What determines the water soluability of a covalent compound?
|
The ability of water to form hydrogen bonds with the compound
|
|
|
How many osmols in 4 litres of 4M MgCL2?
|
48 osmols
|
|
|
How many grams of H3PO4 would be found in 4 liters of .25M solution? Show your work
|
98grams H3PO4
|
|
|
What determines the water soluability of an IONIC compound?
|
The lesser the charge the higher the soluability. Smaller particles are more soluable than larger particles
|
|
|
If you had a solution of 2MNaCl and a solution of 2M C6H12 which would have the higher boiling point and which would have the lower boiling point?
|
Unsure.??? 2M C6H12O6 would have a higher boiling point. 2M Na Cl would have a lower melting point
