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 0 mean? Explain the significance of (a) a very large value...
What does the symbol (aq) mean?Solutions:In the fascinating and often complex chemistry realm, a solution is a homogenous mixture of two or more substances. Solutions frequently exist in the liquid phase of matter; however, gaseous and solid solutions exist as well....
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). Ioni...
What does it mean to displace water? What gives an element its characteristics? What generalizations can you make about combinations that lead to the formation of insoluble ionic compounds? For which of the following will precipitation be expected? a. Qc greater than Ksp b. Qc less than Ksp...
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. ...
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 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 does it mean when a reaction is in equilibrium? How to calculate the equilibrium constant The equilibrium constant, K, for the following reaction is 1.80x10^-2 at 698 K. 2HI(g) yields H2(g)+I2(g) An equilibrium mixture of the three gases in a 1.00 L flask at 698 K contains...
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...
