g All of the molecules below have polar bonds but only one of the molecules is a polar molecule. Which one is a polar molecule?

lbvjy [14]

Answer: $NF_3$

Explanation:

Geometrical symmetry of the molecule and the polarity of the bonds determine the polarity of the molecule.

The molecule that has zero dipole moment that means it is a geometrically symmetric molecule and the molecule which has some net dipole moment means it is a geometrically asymmetric molecule.

As the molecule is symmetric, the dipole moment will be zero as dipole moments cancel each other and the molecule will be non-polar.

As the molecule is asymmetric, the dipole moment will not be zero and the molecule will be polar.

Example: $NF_3$

Thus, we can say that $NF_3$ is a polar molecule.

Identify the type of reaction described in the sentence below. then, write a chemical equation. be sure to specify the states of

natulia [17]

Answer : The type of reaction described in the sentence is Synthesis or Combination

Explanation :

The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as

$4P (s) + 5O_{2} (g) ------> P_{4} O_{10} (s)$

From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.

This type of reaction is known as Combination or Synthesis.

A general form of Synthesis reaction is given below.

$A + B ----> AB$

Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .
