Explanation:
Divide the atoms of gold with Avogadro's number to find the solution.
Answer:
2
Explanation:
Since it has to be 2H2+02→2H20 for it to be balanced.
Answer:
C3H7OH → C3H6 + H20
Explanation:
If we look at the reactant and the product we will realize that the reactant is an alcohol while the product is an alkene. The reaction involves acid catalysed elimination of water from an alcohol.
Water is a good leaving group, hence an important synthetic route to alkenes is the acid catalysed elimination of water from alcohols. Hence the conversion represented by C3H7OH → C3H6 + H20 is an elimination reaction in which water is the leaving group.
The answer is B.
The solvent is the part of solution in which the solute is dissolved. Salt, being the solute, makes it harder for water to crystallize into a formal lattice, requiring a lower temperature to trigger the freezing into an irregular structure.
