when sugar is dissolved in water there is no increase in volume.comment
an inflated air ballon deflates when pricked with a pin. which property of the gaseous state is shown
AT 0 DEGREE CELSIUS AND 760 mm of hg pressure,a gas occupies a volume of 100cubic cm. The kelvin temp. of the gas is increased by one fifth while the pressure is increased one and a half time,calculate the final volume??
inflating a balloon seems to violate Boyle's law.
name of (CH3COO)2 Pb
explain: silver nitrate solution is kept in colored reagent bottles in the laboratory.
give some more examples of deposition?
balance the equation :- Cu + HNO3 = Cu(NO3)2 + NO H2O
what is the symbol and valency of aluminate
1)Give a example of non aqueous solution and solid in non aqueous solvent.
2)classsify the following into true solution and colloidal solution.
blood, sugar sol., salt sol., starch, ink.
3)which will scatter light?
a soap solution, sugar sol., starch sol., milk, blue vitriol.
4)name a mixture used in the construction of buildings and a mixture used as a food?
A pupil decides to separate powdered calcium carbonate from powdered calcium chloride by shaking the mixture with water and filtering. Would this process succeed? Explain your answer.
What is the difference between drying and dehydrating agents...... please it is urgent
give the properties of water responsible for controlling the temperature of our body
What happens when crystals of washing soda are
give reason.. why air is a mixture and not a compound? and also give reason why tap water is a mixture and not compound?

left open in dry air? What is this change named as? Name two industries based on the use of washing soda.give reason.. why air is a mixture and not a compound? and also give reason why tap water is a mixture and not compound?
