5. Hydrochloric Acid + Sodium Hydroxide à Sodium<br> Chloride +
erma4kov [3.2K]

HCl Acid + Sodium Hydroxide ----> Sodium  Chloride + water.

<u>Explanation</u>:

  • The reaction between an acid and a base is known as a neutralization reaction. The reaction of an acid with a base to give salt, water and heat is called neutralization.
  • When hydrochloric acid reacts with sodium hydroxide, sodium chloride and water are produced.  

                             HCl + NaOH → NaCl + H2O + Heat

  • The heat evolved in the neutralization reaction raises the temperature of the reaction mixture.    
  • An electro-electrodialysis process (EED) is utilized to create HCl and NaOH from exchange NaCl. NaOH and HCl arrangements with purity higher than 99.9% are acquired. The experimental estimations of the transitions for HCl and NaOH are contrasted and values determined from the incorporation of the Nernst–Planck electro dispersion conditions.

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas
omeli [17]
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.

Does the coating from another type of candy dissolve in water like M&amp;M’s ?
AleksandrR [38]

The candy coating of the M&M is made of sugar and colored dye. When water comes into contact with the sugary coating, the positive and negative charges in the water molecules pull on the negative and positive charges in the sugary coating, and the coating dissolves.
