Answer : The current will flow more easily and quickly through the copper wire, on application of voltage because copper is a metal which is good conductor of heat and electricity.
In case of germanium it is a semi-conductor means it will behave as a conductor under certain circumstances.
So if we take same length and same thickness of both the wires, current is more likely to flow through the copper wire than the germanium wire.
60 pairs, because A and T are pairs, and C and G are pairs, and since there are only 2 different pairs, they both have to add up tobe 100, so 100-40=60
Answer:
1. Balanced chemical for the given chemical reaction is :
number of mole of sulphuric acid produced = 12.5 mol
number of mole of oxygen required=6.25 mol
Explanation:
1. Balanced chemical for the given chemical reaction is :
from above balanced equation it is clearly that ,
2 mole of sulpher dioxide gives 2 mole of sulphuric acid
1 mole of sulpher dioxide gives 1 mole of sulphuric acid
therefore,
12 .5 mole of sulpher dioxide will givs 12.5 mole of sulphuric acid
number of mole of sulphuric acid produced = 12.5 mol
2 mole of sulphur dioxide needs 1 mole of oxygen gas
so,
1 mole of sulphur dioxide needs 0.5 mole of oxygen gas
therefore 12.5 of sulphur dioxide needs mole of oxygen
number of mole of oxygen required=6.25 mol
The law of conservation of mass states that:
"For any closed system, mass is preserved. This means that the total amount of mass remains constant as mass can neither be created nor destroyed".
Applying this to the decomposition we have,
since the total mass of reactants (water) is 10 grams, therefore, the total mass of products (hydrogen and oxygen) is also 10 grams
