Answer:

I'm pretty sure it's false. It is used to measure the amount of Moles in an element.

I'm sorry if this is incorrect.

How to tell if the self ionization reaction is endothermic
enot [183]

If the self ionization reaction is endothermic then it will shift on right side from equilibrium if we increase the temperature.

<h3>What is endothermic reactions?</h3>

Endothermic reactions are those reactions in which heat or energy is absorbed by the reactants for the formation of product.

If the self ionization reaction is endothermic in nature then in this condition at the equilibrium if we increases the temperature then the formation of ions increases as a result of the shift of the reaction towards the right side.

Hence, by increasing the temperature we can predict whether the reaction is endothermic or not.

A student takes a measured volume of 3.00 M HCl to prepare a 50.0 mL sample of 1.80 M HCL. What volume of 3.00 M HCI
netineya [11]

To solve the question you use the following formula:

concentration (1) × volume (1) = concentration (1) × volume (1)

3 M ×  volume (1)  = 1.8 M × 50 mL

volume (1)  = (1.8 M × 50 mL) / 3 M = 30 mL

Write a balanced net ionic equation for the following reaction. Explain how you arrived at this answer. What did you cancel out?
yaroslaw [1]

 The net ionic equation  is


Ag⁺(aq)  +Cl⁻(aq) →  AgCl(s)


Explanation


AgNO₃ (aq)  + KCl (aq)→ AgCl(s) +KNO₃(aq)



from above  molecular equation break  all  soluble electrolyte  into ions


Ag⁺(aq) +NO₃⁻ (aq) + K⁺(aq) +Cl⁻(aq) →   AgCl (s) + K⁺(aq) + No₃⁻(aq)



cancel the spectator  ions  in both side  of  equation =K⁺  and NO₃⁻  ions



The net  ionic equation is therefore


= Ag⁺(aq)  + Cl⁻(aq) →    AgCl(s)
