A neutralization reaction between an acid and a metal hydroxide will produce water and a salt. Consider the reaction between sodium hydroxide and hydrochloric acid. This would be:
NaOH + HCl --> NaCl + H2O
The resulting products are table salt (NaCl) and water (H2O)

Answer : The correct option is, (a) water and a salt

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base or metal hydroxide to give salt and water as a product that means it reacts to give a neutral solution.

For example :

When sodium hydroxide base react with hydrochloric acid then it react to gives sodium chloride and water as a product.

The balanced chemical reaction will be:

$HCl+NaOH\rightarrow NaCl+H_2O$

Hence, the correct option is, (a) water and a salt

How many chloride ions are in 2.6 moles of CaCl2?

Rama09 [41]

Answer:

31.31× 10²³ number of Cl⁻ are present in 2.6 moles of CaCl₂ .

Explanation:

Given data:

Number of moles of CaCl₂ = 2.6 mol

Number of Cl₂ ions = ?

Solution:

CaCl₂ → Ca²⁺ + 2Cl⁻

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

In one mole of CaCl₂ there are two moles of chloride ions present.

In 2.6 mol:

2.6×2 = 5.2 moles

1 mole Cl⁻ = 6.022 × 10²³ number of Cl⁻ ions

5.2 mol × 6.022 × 10²³ number of Cl⁻ / 1mol

31.31× 10²³ number of Cl⁻

Write me a brief description of a Nerve Signal. (Only one sentence)

astraxan [27]

Description of a nerve signal

The nerve signal, or action potential, is a coordinated movement of sodium and potassium ions across the nerve cell membrane. Here's how it works: As we discussed, the inside of the cell is slightly negatively charged (resting membrane potential of -70 to -80 mV).
