The solubility of AgBrO, in water at 25 °C is measured to be 1.7 Use this information to calculate K for AgBrO3. sp Round your answer to 2 significant digits. x10

A salt has a solubility in water of 2.5 g/L at 25 °C Suppose you mixed 10.0g of this salt with 3.0 L of water in a beaker and allowed the salt to dissolve. The temperature of the solution was kept at 25 °C. Would there be any solid left in the beaker after the salt has dissolved? Select one: O Yes, there would be some solid would be left in the beaker. O No, there would not be any solid left in the beaker. Not enough information is provided to answer this question

Suppose you want to measure the amount of glucose in a can of soda. You can use the data generated in this experiment to help you, but what other data would you need to collect in order to measure the concentration of glucose in the soda? In other words, what additional experimental step(s) would you perform? B I U Ꭶ X X, 14▾ A In order to measure the amount of glucose in a can of soda, one would need to prepare a series of standard solutions w/ an unknown concentrations of glucose using the 0.3M of glucose sol'n and DI water. Therefore, the glucose oxidase assay would be performed on each standard sol'n and the result values would also be measured by a spectrophotometer. A standard curve may then be plotted by absorbances and the unknown concentration of glucose. It may also be necessary to adjust the pH of the soda can sample to preform additional steps. Change Submission Submitted. Waiting on graded response. 14) Once you have collected data from the step(s) proposed in the previous…

The reaction A(aq) + B(aq)  C(aq) + D(aq) has a ΔHrxn = -85 kJ/mol.   This reaction is  endorthermic or exothermic  .  If the temperature of the reaction mixture is increased, equilibrium will shift towards the reactans or products.  This change will decrease or increase the concentration of the reactants and K will increase or deacrease
