how to find in a solution that which component is solute and which component is solvent ...................e.g ......... solution made from 200g h20 and 222g of ethylene glycol

There is a most annoying issue, about how to make sodium hypochlorite solution, from home bleaches that show different ways of strength.

Exactly, I have a bleach that literally says that "it contains cca 40 g/l of active chlorine in the moment of filling".

What is the explanation and calculation way, to make 5% NaOCl solution from it?

Strengths of bleaches are expressed in so many ways (%,vol%,grades of chlorine...) that it makes it very difficult to calculate amounts of bleach and solvent, to make a specific concentration.

What is the bleach strength determined by Cl- ion,ClO- ione amount of NaOCl(?) solved or something else?

Is there any source of comparative values so that this confusion be cleared up?

Looking forward to your response.

Thank you.

way after melting a cristal alum, after cool down it crumbles to the touch.
thanks for your attention.

In the following equations, determine which reactant is the limiting
reactant and which reactant is in excess. The amounts used
are given below each reactant. Show evidence for your answers.

I dont know how to explain that SnO formation from its elements is thermodynamically favorable. I think it must be redox because thats how we explain thermodynamic favorable equations. But i dont know if i can use water molecules because is says From its elements. thank you :)

if i mix hydrogen peroxide with bleach what would be the result.

If i mix hdrogen peroxide with sulpher powder what is the result.

Is it possible to obtain the result in approx. 1 - 2 days.

Determine if HNO3 can dissolve in the following metal:

1) Write a balanced chemical reaction showing how the 2.09g Cu dissolves in HNO3.

I had put down: Cu(s) + 4HNO3(aq) ——> Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
but it's wrong.

2) Determine the minimum volume of 6.3M HNO3 required to completely dissolve the sample (in mL).

Thank you!!
