The strongest type of intermolecular force present between NH2CH3 molecules is the Hydrogen bond

This is further explained below.

<h3>What is the strongest type of intermolecular force present between nh2ch3 molecules?</h3>

Generally, One definition of a hydrogen bond describes it as an electrostatic force of attraction between two electronegative atoms, one of which is a hydrogen atom that is covalently bound to a more electronegative "donor" atom or group and the other of which is an atom that bears a lone pair of electrons and is referred to as the hydrogen bond acceptor.

In conclusion, The hydrogen bond is the sort of intermolecular interaction that is the most powerful when it is present between NH2CH3 molecules.

Which type of matter needs to be separated by chemical methods ( breaking of bonds required ) such as electrolysis or decomposit

Irina18 [472]

The correct answer is compound.

The compounds comprise two or more elements, which are bonded together chemically, and can be dissociated, that is, distinguished by reforming and breaking the chemical bonds, by the decomposition reactions, like thermal decomposition or electrolysis. The process of decomposition generate simpler compounds or individual elements.

What set of coefficients will balance the chemical equation: _NaBr (aq) + _H3PO4 (aq) → _Na3PO4(aq) + _HBr (aq)

GaryK [48]

The Balanced chemical equation for above reaction will be :

$\small{ \mathrm{3NaBr + H_3PO_4 \rightarrow Na_3PO_4 + 3HBr}}$

The Coefficients will be :

$NaBr - 3$

$H_3PO_4 - 1$

$Na_3PO_4 - 1$

$HBr - 3$

So, Correct option is :

A. 3, 1, 1, 3

Find the density of an object that has a mass of 6.13 g and volume of 1.50 cm³.

storchak [24]

Answer:

≈ 4.10 g/cm³

Explanation:

Hi there !

Density formula

d = m/V

d = 6.13g/1.5cm³

d = 4.08(6) g/cm³ ≈ 4.10 g/cm³

Good luck !

A weak bond called a ______ bond results from an attraction between a slightly positive region in a molecule and a slightly nega

tamaranim1 [39]

Answer: The weak bond having slightly positive region and a slightly negative region is polar covalent bond.

Explanation:

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms. For Example: HCl, $CH_4$ etc..

They are of two types:

Polar covalent bond: This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond.

In this bond, a dipole is created. More electropnegative atom will have a slight negative charge and less electronegative atom will have a slight positive charge. For Example: $CO_2,NO_2$ etc..

Non-polar covalent bond: This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: $N_2,O_2$ etc..

Hence, the weak bond having slightly positive region and a slightly negative region is polar covalent bond.
