Describe what happens when ionic and covalent (molecular) substances dissolve. A(n) aqucous covalent compound dissolved in water, H2O(l), will produce in solution. A(n) dissolved in water, H 0(), will produce in solution. Answer Bank ionic compound aqueous anions aqueous cations covalent compound When potassium chromate, K, CrO, is dissolved in water, what ions are produced? O K?+ + Cro O 2K+ + Cv6+ + 402- Ono ions are formed O 2K+ + Cro O 2K+ + Cr?- +20,
When an ionic compound dissolves in water, the cations and anions are separated. Ions in solution will result in that solution conducting electricity, an electrolyte. Some solutions are strong electrolytes while others are weak electrolytes. 1. What do you think is giving rise to electrical conductivity? ions in a crystal 2. This is a diagram showing ions in a crystal. Draw a diagram showing the particles in 1) strong electrolyte, and 2) weak electrolyte. Pay attention to how the water...
5) When KCl dissolves in water A) the Clions are attracted to dissolved K+ ions. B) the Clions are attracted to the partially negative oxygen atoms of the water molecule. C) the K+ ions are attracted to Clions on the KCl crystal. D) the Kions are attracted to the partially negative oxygen atoms of the water molecule. E) the Kions are attracted to the partially positive hydrogen atoms of the water molecule. 6) in water, a substance that partially ionizes...
Decide whether each of the following is water-soluble. If soluble, tell what ions are produced when the compound dissolves in water (a) NajCO (b) CuSO (c) NiS (d) BaBe. b. Predict the products of each precipitation reaction. Balance the equation, and then write the net ionic equation. (a) NiCl(aq) + (NHS(aq) th) Mn(NOlaq) + Na POalaq) Complete and balance the equations for the following acid-base reactions. Name the reactants and products. (a) CH,CO H(aq) + Mg(OH) (s)- (b) HCIOa(aq) +NH(aq)-...
Homework 4: Unit 2 Part 2: Chemical Reactions Hints are given in some of the problems to get you started. By the time you get to taking the exam, those hints will not be there so you should be able to do these problems without the hints. 1. Balance the following chemical reaction using the smallest possible integer coefficients. AgNO, (aq) + Cu (s) - Cu(NO3)2 (aq) + Ag (s) 2. Write a balanced equation for the reaction described, using...
g of sodium nitrate (NaNO,) dissolves in 100 g of water at 20°C. Is this solution saturated or unsaturated? Wha t would happen if you added ten more grams of sodium nitrate to the solution? What would if you added the ten grams and raised the temperature to 40 C? lution is unsaturated. Adding ten additional grams of solute (NaNO,) would result in a homo geneous solution. Raising the temperature of the solution by 20°C would not affect the solution...
2. What is the total concentration of all ions (the sum of their individual concentrations) in aqueous solutions of the following? Hint: Each substance is an electrolyte that dissociates in water to produce ions. Use the link table of polyatomic ions if you do not recognize the polyatomic ion. For example, Na2SO4 -> 2Na1+ + SO42- when it dissolves, so a 1 M soln of Na2SO4 is 2M in Na1+ and 1M in SO42- and the total concentration of ions...
Chem 1 problem. Please answer all with steps. Thank you so much 2. When 26.6 g of potassium chloride dissolves in 300.0 g of water, the temperature drops from 26.1°C to 11.7°C. The C of the calorimeter is 22.0 J/oC. cal (a) Write an equation for solid potassium chloride dissociating into ions when it dis- solves in water. (b) Is the reaction endothermic or exothermic? (c) What is the sign of AH? (d) What is the value of "q" for...
