What is standardization in chemistry and what is its importance? x + y = 9.0, 0.50x + 0.20y = 3.90. What is the value of x and y? What is the value of x? 10(3.71x) = 315.2(1.19+7.59) What does the range value of
If two liquids are immiscible, does that mean that there is zero solubility between them? Given that Ksp = 1.7 x 10-5 for PbCl2, calculate: a) the solubility of PbCl2 in water (in mole/litre) b) the solubility of PbCl2 (in mole/litre) in a 0.15 M solution of MgCl2 in water. ...
Ionic equilibrium is also a type of equilibrium where the amounts of products and reactants do not change over time. However, this does not mean that the reaction has stopped; rather, the reaction is proceeding in a way that keeps the amounts unchanged (the net change is zero). Ion...

What does it mean when a chemical reaction has reached equilibrium? What are different ways in which an equilibrium system can be stressed? What effects does this have on the products and reactants and what are some examples? The equilibrium expression below fits which chemical reaction? [ C ...
What happens to the Ksp value of a solid as the temperature of the solution changes? Explain in both cases if the temperature of the solution increases and decreases. What happens to the particles of a solid when the solid changes into a liquid? A. They...
What is the solute in saltwater? What does it mean to standardize a solution? What is neutralization? What is a nonvolatile solute? What is the solution for ice loss? What is an eutectic mixture? What is paper chromatography? What solvent will dissolve wax?
What does the range value of 0 mean?Question:What does the range value of 0 mean?Range:If we found any zero in data irrespective of the highest or the lowest number this range can be used to calculate the range. The range can be a difference between highest as well as lowest value.An...
If two liquids are immiscible, does that mean that there is zero solubility between them? What are three ways to make a sugar cube dissolve more quickly in water? What are examples of soluble and insoluble salts? A solution contains 4.38 g of urea, CO(NH2)2, a nonvolatile compound, diss...
