According to Arrhenius definition of acids, $NH4^+$ is an acid.

According to Arrhenius definition of acids and bases, acid is any substance that produces hydrogen ion in solution as its only positive ion.

Following this definition, let us now consider what happens when $NH4^+$ is introduced into a water;

$NH4^+$ (aq)-------> NH3(aq) + $H^+$ (aq)

Hence, according to Arrhenius definition of acids, $NH4^+$ is an acid.

For another example of Arrhenius acids, see

How were the elements in the first periodic table arranged?

Snezhnost [94]

Based on atomic mass

Explanation:

Elements were arranged on the first periodic table based on their atomic masses.

The mass of an atom is made up of the mass of the nucleus which contains the protons and neutrons.

Dimitri Mendeleev was the first person credited for arranging elements periodically.
He was said to have been inspired while playing his game of solitaire on a train.
On his table, he left spaces for the atomic masses of elements not yet discovered.
Today, the periodic table is based on the atomic numbers of elements. This is the number of protons in an atom.

Sulfur and fluorine react in a combination reaction to produce sulfur hexafluoride:

mixer [17]

In a particular experiment, the per cent yield is 79.0%. This means that in this experiment, a 7.90-g sample of fluorine yields is 7g of SF6.

<h3>How is Sulphur hexafluoride formed?</h3>

Sulfur Hexafluoride is a disparity agent formed of an inorganic fluorinated inert gas comprised of six fluoride atoms bound to one sulfur atom, with possible diagnostic activity upon imaging.

Thus, a sample of fluorine yields 7g of SF6.

_______ is the classic structural formula for all the addictive narcotics

oee [108]

The answer to this statement is codein. Codein, or 3-Methylmorphine by its IUPAC name, is an opiate used as pain reliever and suppressor of coughs. Its structural formula is shown in the picture. The patient's dosage of these narcotics should be strictly prescribed by the doctor. When patients take this, they feel euphoria, hence, they tend to crave for that feeling once it's gone. Too much dosage of this drug would lead to addiction. Examples of drugs with this structural formula are Cotabflu, Nalex AC, T-Koff and Pediatuss.
