Why is water a polar compound?

anastassius [24]

Answer:

Water is a unique molecule and thus consists of unique properties. It is considered polar because of its charges and its bent shape. The two oxygen are negative and the hydrogen is positive. This creates two poles, making the molecule polar. This is an example of polar covalent chemical bonding.

Calculate the volume of chlorine molecules produced at room temperature and pressure, when 234g of sodium chloride are electroly

rewona [7]

The volume of chlorine molecules produced at STP would be 96 dm³.

<h3>Stoichiometric problem</h3>

Sodium chloride ionizes during electrolysis to produce sodium and chlorine ions as follows:

$NaCl --- > Na^+ + Cl^-$

This means that 1 mole of sodium chloride will produce 1 mole of sodium ion and 1 mole of chlorine ion respectively.

Recall that: mole = mass/molar mass

Hence, 234 g of sodium chloride will give:

234/58.44 = 4.00 moles.

Thus, the equivalent number of moles of chlorine produced by 234 g of sodium chloride will be 4 moles.

Recall that:

1 mole of every gas at Standard Temperature and Pressure = 24 Liters.

Hence:

4 moles of chlorine = 4 x 24 = 96 Liters or 96 dm³.

The metal sodium is obtained by electrolysis of common table salt (sodium chloride, nacl). how much sodium chloride needs to be

Bogdan [553]

Solve first for the number of moles of sodium given that the mass is 2500 g by dividing the given mass by the molar mass of sodium.
moles sodium = 2500 g / 23 g/mol
moles sodium = 108.7 moles
Since in every mole of NaCl, there is only one mole of sodium then, we conclude that there are also 108.7 moles of NaCl. Multiplying the number of moles to the molar mass of sodium chloride (58.44), the answer would be 6,352.17 grams.
