You dissolve 57.00 g sample of sodium phosphate solid in 599.o grams of water. All of the solid dissolves and the ionic compound breaks into individual ions when it dissolves to form an aqueous solution. a) calculate the total number of sodium ions present in the solution b) Calculate the ratio comparing the number of water molecules in the solution to the total number of ions ( cations and Anions) in the solution c) If the total volume of the...
Question 11 pts Match the definition with it's correct word. A mixture composed of a solute dissolved in a solvent. [ Choose ] Solute Solution Soluble Miscible Insoluble Solvent Immiscible The greater substance that does the dissolving in a solution. [ Choose ] Solute Solution ...
A student placed 14.0g of glucose (C6H1206) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 35.0-mL sample of this glucose solution was diluted to 0.500mL . How many grams of glucose are in 100mL. of the final solution?
7. If an ionic bond is stronger than a dipole-dipole interaction, how can water dissolve an ionic compound? None of these The ion-dipole interactions of a bunch of water molecules gang up on the strong ionic bond and pull it into the solution. The ions never overcome their interatomic attraction and therefore are not soluble. The ionic bond is weakened by the ion-dipole interactions and ionic repulsion ejects the ions from the crystal. The ion-dipole...
37. Write the balanced net ionic equation for the reaction between the water insoluble solid Mg(OH)2(s) and an aqueous solution of the strong acid Hl(aq). 38. In the following reaction identify the species that is the oxidizing agent and the species that is the reducing agent. Mg(s) + 2H(aq) → Mg() + H2
QuesLIVIT 211.JPUITLS) The beaker below represents a solid ionic compound that has been dissolved in water to produce an aqueous solution. Based on the ratio of ions (assume one color is a cation and the other an anion), select all compounds below that could possibly represent the compound in the beaker below. Al2(SO4)3 Naci CaCl2 Na3PO4 Fe2(SO4)3 Na2CO3
A. Hydroiodic acid is placed in a beaker of water, and aluminum carbonate is placed in a separate beaker of water. The two beakers and their contents are allowed to sit for a period of time during which the contents are gently stirred. The contents of these two beakers are then mixed together. If a reaction occurs, the coefficient of carbon dioxide gas as a product in the balanced molecular equation is _____. You must show the correctly balanced molecular...
A 45.5 gram sample of a mineral is placed in boiling water until its temperature is 100 degrees C. It is then placed in 255 grams of H20 with a temperature of 22.5 degrees C. The final temperature of the system settles at 32.4 degrees C. What is the specific heat of the mineral?
A sample of water is suspected to contain silver ions. What can be done to support this claim? Select the correct answer below: Add HCl to see if a precipitate forms. Acidify the solution and add H2S to see if a precipitate forms. Basify the solution and add H2S to see if a precipitate forms. Add (NH4)2HPO4 and NH3 to the solution to see if a precipitate forms.
