The subscripts tell you <em>how many atoms</em> of an element are in one formula unit of a compound.

If there is no subscript, there is only one atom of the element.

In one formula unit of Na₂PO₃F, there are

Two atoms of sodium (Na)

One atom of phosphorus (P)

Three atoms of oxygen (O)

One atom of fluorine (F)

Rainbow [258]

Hello!

The pressure of the gas when it's temperature reaches 928 °C is 3823,36 kPa

To solve that we need to apply Gay-Lussac's Law. It states that the pressure of a gas when the volume is left constant (like in the case of a sealed container like an aerosol can) is proportional to temperature. This is the relationship derived from this law that we use to solve this problem:

$P2= \frac{P1}{T1}*T2= \frac{103 kPa}{25}*928=3823,36 kPa$

Have a nice day!

Discuss elements and compounds by completing the following paragraph

pychu [463]

Elements are substances that are made up of the same atoms which are capable of taking part in a chemical reaction.

There are different types of elements which are represented by symbols gotten from the first letter or the first and any other letter in the name of the element.

Examples of elements include:

Hydrogen (H)

Carbon (C)

Nitrogen (N)

Sodium (Na)

When two or more of these elements combine together through a chemical bond, it leads to the formation of compounds.

Example of a compound includes:

NaCl: The element sodium combine, through electrochemical bonding, with another element chlorine to form the compound sodium chloride.

The lone pair of electrons on the oxygen atom in an ester can form hydrogen bonds in some situations, but esters cannot form hyd

mixer [17]

Answer:

Esters have lower boiling point than alcohols.

Explanation:

Esters are the fruity smelling compounds which are formed from carboxylic acid and alcohol with the removal of water.

The general formula for the ester is RCOOR' which is prepared from RCOOH acid and R'OH alcohol.

Ester can not form strong hydrogen bond as there is no hydrogen attached to the electronegative atom in the ester and thus cannot form hydrogen bonds with each other.<u> Due to this factor, the interactions within the molecules of the ester is lower than that of alcohols which exist in strong hydrogen bonding. As a result, ester can be easily boiled when compared to the alcohols and thus they have lower value of boiling points.</u>
