The reaction enthalpy for the given reaction has to be calculated and the reaction has to be identified that whether it comes under exothermic or endothermic reaction. Concept Introduction: Enthalpy is the amount energy absorbed or released in a process. Exothermic reaction: Exothermic reactions are those in which evolution of heat takes place during any chemical reaction . They release heat because the reactant molecules require less heat for breakage of bonds than the product molecules. Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any chemical reaction.

Interpretation Introduction

Interpretation:

The reaction enthalpy for the given reaction has to be calculated and the reaction has to be identified that whether it comes under exothermic or endothermic reaction.

Concept Introduction:

Enthalpy is the amount energy absorbed or released in a process.

Exothermic reaction: Exothermic reactions are those in which evolution of heat takes place during any chemical reaction. They release heat because the reactant molecules require less heat for breakage of bonds than the product molecules.

Endothermic reaction: Endothermic reactions are those in which heat is absorbed during any chemical reaction.

28. A neutralization reaction occurs when 120.00 mL of 0.500 mol/L LiOH and 160.00 mL of 0.375 mol/L HNO3(aq) are mixed in an insulated cup. Initially, the solutions are at the same temperature. If the highest temperature reached during mixing was 24.5°C, what was the initial temperature of the solutions? LiOH(aq) + HNO3(aq) →→→ LINO3(aq) + H₂O(l) + 53.1 kJ Assume that both of these solutions have a density of 1.00 g/mL and a specific heat capacity of 4.19 J/g.°C.

Aluminum in the Al3 + form can be precipitated as Al (OH) 3, adding ammonia to an aluminum solution, but the precipitate is usually gelatinous and difficult to filter. Precipitation from a homogeneous solution provides a more filterable precipitate. The reaction used in this process is the hydrolysis of urea: (image attached) Suppose this reaction occurs in a 100.00 mL solution with an initial Al3 + concentration of 1.50x10-3 mol / L. How many moles of urea must be hydrolyzed to supply enough hydroxide to stoichiometrically combine Al3 + and form the precipitate Al (OH) 3?

Q) Drinking water may contain several unwanted ions such as phosphate ions. In order to remove the phosphate ions from the drinking water, a solution of calcium hydroxide can be added. As a result, a solid Ca5OH(PO4)3 is formed and isolated by filtration and a hydroxide ion are also formed. The reaction for this process is below: 5 Ca(OH)2 (aq) + PO43- (aq) → Ca5OH(PO4)3 (s) + OH- (aq) a) If 3.00 mL of 0.100 M calcium hydroxide is mixed with 4.00 mL of an aqueous solution of 0.0800 M phosphate ions (PO43-). What is the mass of Ca5OH(PO4)3 that can be isolated from the reaction? b) How many moles of the excess reactant remains unreacted? c) What is the concentration of the hydroxide ions in this solution? d) What is the mass of calcium (in grams) that can be recovered?
