Identify the single displacement reaction.
pishuonlain [190]

Answer : The correct option is, (D)

Explanation :

Option A reaction : C_4H_{12}+7O_2\rightarrow 6H_2O+4CO_2

It is a combustion reaction. A reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.

Option B reaction : 2H_2+O_2\rightarrow 2H_2O

It is a combination reaction. A reaction in which the two or more reactants react to give a product.

Option C reaction : Al_2S_3\rightarrow 2Al+3S

It is a decomposition reaction. A reaction in which a reactant decomposes to form two or more products.

Option D reaction : Cl_2+2KBr\rightarrow 2KCl+Br_2

It is a single displacement reaction. It is a reaction in which the more reactive element displace the less reactive element.  In this reaction, most reactive element chlorine displaces the less reactive element bromine.

Hence, the correct option is, (D)

What is the mass, in grams, of 7.20×1020 molecules of caffeine, c8h10n4o2?
pickupchik [31]
To determine the mass, you need to know the molecular weight of the c8h10n4o2 . The molecular weight of <span>c8h10n4o2 would be: 8*12 + 10*1 + 4*14 + 2*16= 194g/mol.
To convert the number of molecules into moles, you need to divide it with 6.02 * 10^23. The calculation of the mass of </span>c8h10n4o2 would be: 
(7.20×10^20 molecules)  /(6.02 * 10^23 molecule/mol)  * 194g/mol= 232 * 10^-3 grams= 0.232 grams
