PLEASE HELP ME! VERY IMPORTANT SEE ATTACHED

Chemistry
1 answer:
Sergeeva-Olga [200]3 years ago

Answer:

K₃PO₄ and HBr  

Explanation:

The premise of your question is incorrect.

A strong electrolyte is a substance that ionizes completely in solution.

For example, CaCO₃, is a strong electrolyte, even though it is insoluble.

Very little of it goes into solution, but every bit that does dissolve separates completely into ions.

In an ionic equation, we write it as CaCO₃(s) because it is insoluble.

An ionic equation shows soluble strong electrolytes as ions.

K₃PO₄ is a soluble strong electrolyte because salts of Group 1 metals are soluble.

HBr is a strong acid and  a strong soluble electrolyte. In aqueous solution it dissociates completely into H⁺ and Br⁻.

Acetic acid is a soluble weak electrolyte. It is a weak acid, so only a few of its molecules dissociate into ions.

What are the units used to measure specific heat capacity?
Andrews [41]

The units used to measure specific heat capacity is Joules per kilogram per Kelvin.

<h3>What is specific heat capacity?</h3>

It is the amount of heat absorbed per kilogram of material when the temperature rises by 1 Kelvin.

Specific heat capacity C is the Joules of energy in form of heat per kilogram per Kelvin temperature. The units represented by

C = ___ J/kg.K

Thus, the units used to measure specific heat capacity is Joules per kilogram per Kelvin.

A. What is the pH of a solution with a [H+] of 6.8 x 10^-11?
inysia [295]

Answer:

[H+] = 6.8×10^-11

so, pH = - log[H+]

= - log [6.8×10^-11]

= -(-10.167)

= 10.167

alexgriva [62]
I think the answer would be dependent variable. An unknown or changeable quantity is called a dependent variable. It <span>is what you measure in the experiment and what is affected during the experiment. Hope this answers the question. Have a nice day.</span>
