guys,you could balance it yourselves.
also,it isnt wrong because the paper asks you to only convert the salt into PbSO4 so it doesnt matter whether the insoluble salt coats the surface or not

the answer is ACTIVE TRANSPORT.

ths is because a hypertonic soln contains less water and hypotonic soln cotains more water.osmosis is movement of water molecules from their region of higher conc to their region of lower conc.

however,the water molecules in this case are moving from their region of lower conc to their region of higher conc.thus it is active transport though the question doesnt mention the use of energy

mhmm...maybe its just not in the right position thats why

no its alright as long as you write the KIND of particles present

ITS IS LOGICALLY FLUORINE BUT CHLORINE IS AN EXCEPTION SO ITS ABSOLUTELY RIGHT

Al203 + 2NaOH—›2NaAlO2+H2O

NaCl is NOT a deliquescent!!!impure nacl contains MgCl2 which is deliquescent and makes salt sticky in moisture

the work done by the moon is 0 because:

the direction in which the force is applied and the displacement are perpendicular to each other.

therefore cos 90=0

word done=FScos 90=0

1-its an important component in steel alloy and gives it strength

2-removes impurities and makes it immune to rusting
