The general formula of an acid is HX where H+ acts as the cation while X can be a halogen (Cl-, Fl-, Br-, etc) and acts as the anion. There are also cases where X is an ion like SO42-, which brings two atoms of H in the formula. Strong acids dissociate completely while weak acids do not.

Answer: The general chemical formula for an acid is given below.

Explanation:

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

The general chemical formula for an acid follows:

$HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)$

where,

$H^+$ is the cationic part and is named as hydrogen ions

$A^-$ is the anionic part.

The nomenclature of the acids that are derived from the anions attached to hydrogen ion:

If the name of the anion attached ends with -ate, then the prefix of the acid is -ic. For Example: $H_3PO_4$ , the anion is phosphate and the name of the acid is phosphoric acid.
If the name of the anion attached ends with -ite, then the prefix of the acid is -ous. For Example: $H_2SO_3$ , the anion is sulfite and the name of the acid is sulfurous acid.
If the name of the anion attached ends with -ide, then the prefix of the acid is -ic. For Example: HCl, the anion is chloride and the name of the acid is hydrochloric acid.

Hence, the general chemical formula for an acid is given above.

soldier1979 [14.2K]

Answer: The correct answer is Option 1.

Explanation:

Control group is the group used in the experiment by the researchers in which no change in the variable is done. It is then set as a benchmark for the groups which are being tested.

We are given 4 groups which are being experimented for the flotation of an egg in water. As in Cup 1, there is no addition of salt and hence there is no change in the variables. So, this is set as a benchmark fro the cups which are further used in the experiment conducted.

Hence, the correct answer is Option 1.

The density (mass/volume) of aluminum is 2.70 times. 103 kilograms per cubic meter (kg/m3). what is the mass of an aluminum cyli

wariber [46]

Mass of aluminum = (1.50 m^3)( 2.70 x 10^3 kg/m^3) = 4050 kg

The intention of density is the assembly per volume of the substance. This is an intrinsic property consequently the size (or any external feature) does not change this effects.

<h3>What is Aluminum?</h3>

Aluminum is a silvery-white metal, the 13 elements in the regular table. One surprising fact regarding aluminum is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most standard chemical essence on our planet after oxygen and silicon.

The formed aluminum is in everyday use in mining, manufacturing, and trade in the United States; the formed aluminum is used with reasonable uniformity in Great Britain and typically by chemists in the United States.

Aluminum (Al), also spelled aluminum, chemical component, a weightless silvery-white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most plentiful metallic component in Earth's crust and the numerous widely used nonferrous metal.
