Answer:

0.025 L

Explanation:

The production of oxygen in the electrolysis of water is;

4OH^-(aq) -----> 2H2O(l) + O2(g) + 4e

Since 1 F = 96500C

molar volume of a gas = 22.4 L

From the reaction equation;

4 * 96500 C yields 22.4 L of oxygen

(3 * 60 * 60 *  0.0400) C yields (3 * 60 * 60 *  0.0400) * 22.4/4 * 96500

= 9676.8/386000

= 0.025 L

Aleksandr [31]

Answer: Correct name will be is aluminum bromide

Explanation:

In a molecular formula ,AlBr_3

Aluminium atoms present = 1  

Bromine atoms present = 3

Charge on aluminium is +3 and charge on bromine is -1.

While naming:

  • Name of the cation is written first. Simple name of the element is written
  • After name of cation name of an anions written with suffix 'ide' in the end.

So, the name of AlBr_3 will be aluminium bromide.
