These two beakers represent solutions of HCl and NaOH. Describe a third beaker showing the ions that remain after the reaction h
DENIUS [597]

Number of ions in the third beaker:

4 Cl⁻ ions

5 Na⁺ ions

1 OH⁻ ion

Explanation:

If you mix the backers the following chemical reaction will occur:

HCl + NaOH → NaCl + H₂O

In the ionic form you write the equation:

H⁺ (aq) + Cl⁻ (aq) + Na⁺ (aq) + OH⁻ (aq) → Cl⁻ (aq) + Na⁺ (aq) + H₂O (l)

where:

(aq) - aqueous (dissolved in water)

(l) - liquid

Number of ions in the first beaker:

4 Cl⁻ ions

4 H⁺ ions

Number of ions in the second beaker:

5 Na⁺ ions

5 OH⁻ ions

Number of ions in the third beaker:

4 Cl⁻ ions

5 Na⁺ ions

1 OH⁻ ion

The rest of H⁺ and OH⁻ ion reacted to form water.

Natali [406]

cesium chloride is another chloride that could be used instead of the calcium chloride dihydrate to produce a solid precipitate with aqueous sodium carbonate

A mineral salt called cesium chloride (CsCl) is occasionally ingested or administered intravenously to cancer patients seeking alternative therapies. However, the FDA has not yet approved any cesium chloride products to treat cancer or other disorders.

In isopycnic centrifugation, cesium chloride is a common medical compound used to separate different forms of DNA. It is a reagent used in analytical chemistry to distinguish ions based on the hue and shape of the precipitate.

Cesium chloride is not proven to be effective in treating cancer. As an alternative to chemotherapy for cancer, cesium chloride is pushed. Supporters assert that cesium prevents tumor cells from proliferating by neutralizing the poisons they release.
