Chemistry

Answer:

The variation in attraction of some atoms causes hydrogen bonding

Explanation:

Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom.

This gives the molecule a permanent dipole moment, it makes it polar, so it acts like a magnet and attracts the opposite end of other polar molecules.

What is hydrogen bonding?

A hydrogen bond is a partial intermolecular bonding interaction between a lone pair on an electron rich donor atom.

Hydrogen bonding occurs between a hydrogen atom and an electronegative atom (e.g., oxygen, fluorine, chlorine). The bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces (5 to 30 kJ/mol). A hydrogen bond is classified as a type of weak chemical bond.

A sample of kerosene has a mass of 36.4g. It’s volume is 45.6mL. What is the density of kerosene?
stira [4]

Answer:

<h2>Density = 0.8 g/cm³</h2>

Explanation:

The density of an object can be found using the formula

<h3>Density(\rho) =  \frac{mass}{volume}</h3>

From the question

mass of kerosene = 36.4 g

volume of kerosene = 45.6 mL

To find the density substitute the values into the above formula and solve

We have

<h3>Density =  \frac{36.4}{45.6}</h3>

= 0.7982

We have the final answer as

<h3>Density = 0.8 g/cm³</h3>

Hope this helps you
