What is produced by a neutralization reaction between an arrhenius acid and an arrhenius base?
stepladder [879]

Answer: Salt and Water

Explanation:

An Arrhenius acid (HCl) can best be defined as any substance that when added to water increases the concentration of H+ ions.

While an Arrhenius base (KOH) is any substance that when added to water increases the concentration of OH- ions.

When an Arrhenius acid such as HCl reacts with an Arrhenius base such as KOH, the end products will be salt and water, in a process called Neutralization Reaction.

HCl (aq) + KOH (aq)  -------> KCl (aq) + H2O (l)

the triple point of co2 occurs at nearly 1000 times greater pressure and at a lower temperature than the triple point of h2o. ba
IceJOKER [234]

Since liquid CO2 cannot exist at pressures lower than 5.11 atm, the triple point is defined as 56.6 °C and 5.11 atm.

Are CO2 liquids explosive?

Although it can impair judgement at high doses, carbon dioxide is neither poisonous nor combustible. Asphyxiation is typically seen as the primary risk associated with CO2. The Boiling Liquid Expanding Vapour Explosion, however, is a serious risk connected to compressed CO2 (BLEVE)

What PSI does CO2 turn into liquid at?

Only at pressures more than 5.1 atm does liquid carbon dioxide form; the triple point of carbon dioxide is approximately 518 kPa at 56.6 °C. Depending on the pressure, the liquid's boiling point ranges from -70°F to +88°F. The expansion ratio when vaporised at 60°F is 535:1. CO2 is a gas or liquid.

Based on the information in the table, which of the following arranges the bonds in order of decreasing polarity?
patriot [66]

Polarity is the chemical property based on the electric charge and orientation of the poles. Al−O>H−Br>As−S is arranged in decreasing order of polarity. Thus, option d is correct.

<h3>What is polarity?</h3>

Polarity is a chemical property of the distribution of the electrical charges over their respective atom in the molecule joined by the bonds. The relation between the polarity and the difference in electronegativity is directly proportional.

The electronegativity difference between the elements are:

  • Al−O = 1.8
  • H−Br = 0.8
  • As−S = 0.4

As the electronegativity difference between Al−O = 1.8 is the highest it will have the highest polarity followed by H−Br = 0.8, and As−S = 0.4, with the lowest polarity.

Therefore, option D. Al−O>H−Br>As−S is arranged in decreasing order of polarity.
