It is make the molecule polar.
serg [7]3 years ago
4 0

Explanation:

A water molecule contains two hydrogen atoms bonded with an oxygen atom. That is, formula of water is H_{2}O.

Since there is high difference in electronegativity of both hydrogen and oxygen. Thus, there will be uneven distribution of charge on a water molecule as hydrogen will have a positive charge whereas oxygen will have a negative charge.

This will also make the water molecule polar in nature.

If a 0.2g of oil consumed 1ml of sodium thiosulphate, calculate its iodine value and classify the oil?
marta [7]

Iodine value is a measure of the degree of unsaturation in fats and oils. It is essentially the number of grams of iodine consumed by 100 g of fat. If the iodine number is in the range of 0-70 then it is a fat, any value above 70 is considered an oil.

Formula:

Iodine number = (ml of 0.1 N Thiosulphate blank- ml of 0.1N thiosulphate test) * 12.7 *100/1000* wt of sample

vol of thiosulphate required to titrate test sample (given oil) = 1 ml

wt of sample = 0.2 g

Information on the volume of thiosulphate required to titrate the blank solution is essential for calculation.

Iodine number = (X-1.0) * 12.7 * 100/1000* 0.2 = (X-1.0)*6.35

What kind of intermolecular forces act between two ammonia molecules
iragen [17]

Answer:

extensive hydrogen bonding

Explanation:

The high boiling points of water, hydrogen fluoride (HF) and ammonia (NH3) is an effect of the extensive hydrogen bonding between the molecules. The London dispersion force is caused by random and temporary changes in the polarity of atoms, caused by the location of the electrons in the atoms' orbitals.

Hope this helps :)
