Answer : The correct option is, (B) 2, 3 and 6.

Explanation :

Combustion reaction : It is a type of reaction where a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.

In general,

$Hydrocarbon+O_2\rightarrow H_2O+CO_2$

For example : Ethane react with oxygen to give carbon dioxide and water.

$C_2H_8+4O_2\rightarrow 2CO_2+4H_2O$

In the given list, $O_2$ is a reactant and $CO_2,H_2O$ are the products.

Therefore, the correct answer is, (B) 2, 3, and 6

In a certain electrolysis experiment, 1.24 g of Ag were deposited in one cell (containing an aqueous AgNO3 solution), while 0.65

Answer:

The correct answer is 169.56 g/mol.

Explanation:

Based on the given information, the mass of Ag deposited is 1.24 g, and the mass of unknown metal X deposited in another cell is 0.650 g. The number of moles of electrons can be determined as,

= 1.24 g Ag * 1mol Ag/107.87 g/mol Ag * 1 mol electron/1 mol Ag ( the molecular mass of Ag is 107.87 g/mol)

= 0.0115 mole of electron

The half cell reaction for the metal X is,

X^3+ (aq) + 3e- = X (s)

From the reaction, it came out that 3 faraday will reduce one mole of X^3+.

The molar mass of X will be,

= 0.650 g/0.0115 *3 mol electron/1 mol

= 56.52 * 3

= 169.56 g/mol
