Stoichiometry A metal oxide is reduced by heating it in a stream of hydrogen. After complete reduction, it is found that 3.15 gm of the oxide has yielded 1.05 gm of the metal. It may be inferred that the Atomic weight of the metal is 2 Equivalent weight of the metal is 4 Equivalent weight of the metal is 8 Atomic weight of the metal is 4 Atomic weight of the metal is 2 Equivalent weight of the metal is 4 Equivalent weight of the metal is 8 Atomic weight of the metal is 4 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry In case of a solution (not of a solid in a liquid), whose total volume is more than the sum of volumes of its components in their pure states, solubility is Unchanged by the pressure change Increased with the increase in pressure Independent of the temperature Decreased with the increase in pressure Unchanged by the pressure change Increased with the increase in pressure Independent of the temperature Decreased with the increase in pressure ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry A perfectly insulated container of volume V is divided into two equal halves by a partition. One side is under vacuum, while the other side has one mole of an ideal gas (with constant heat capacity) at 298 K. If the partition is broken, the final temperature of the gas in the container Will be 298 K Can not be determined Will be greater than 298 K Will be less than 298 K Will be 298 K Can not be determined Will be greater than 298 K Will be less than 298 K ANSWER DOWNLOAD EXAMIANS APP
