Hello!
In this case, since we can evidence that the ice is firstly undergoing a melting process at constant 0.0 °C, whose associated enthalpy change is:
Next, the formed liquid water undergoes a heating from 0.0 °C to 22°C, to the associated enthalpy change is:
Thus, the total enthalpy change, or heat added to the system turns out:
Best regards!
The periodic table is the arrangement of the elements based on their atomic numbers. The theoretical yield of lithium bromide will be 151 gm.
<h3>What is a theoretical yield?</h3>A theoretical yield is the estimation of the number of moles of product formed in relation to the reactants consumed in a reaction.
The balanced chemical reaction can be shown as:
From the reaction, it can be seen that the moles of all the compounds and molecules are 1.
The molar mass of lithium hydroxide is calculated as:
6.94 + 15.999 + 1.008 = 23.947 gram per mol
The molar mass of hydrogen bromide is calculated as:
1.008 + 79.904 = 80.912 gram per mol
The moles of lithium hydroxide is calculated as:
The moles of hydrogen bromide is calculated as:
From this, it can be said that hydrogen bromide is a limiting reagent as it has fewer moles than LiOH.
The molar mass of lithium bromide is given as, 6.94 + 79.904 = 86.844 grams per mol
Mass of lithium bromide formed will be:
Therefore, the theoretical yield of lithium bromide is option C. 151 gm.
