Answer:
Explanation:
In this case, we have to start with the <u>reagents</u>:
The compounds given by the problem are:
-) <u>Nitrogen gas</u> = 
-) <u>Water vapor</u> = 
-) <u>Aluminum oxide</u> = 
Now, we can put the products in the <u>reaction</u>:
When we <u>balance</u> the reaction we will obtain:
Now, for the enthalpy change, we have to find the <u>standard enthalpy values</u>:
With this in mind, if we <u>multiply</u> the number of moles (in the balanced reaction) by the standard enthalpy value, we can calculate the energy of the <u>reagents</u>:
And the <u>products</u>:
Finally, for the total enthalpy we have to <u>subtract</u> products by reagents :

Explanation:
So here's the thing . Sugar molecule is a molecular solid . It a relatively weak molecule
We all know the formula of glucose ( which is a sugar type molecule ) which is C12 H22 O 11 . This is basically bonded together by dipole dipole forces ( remember that this force of attraction is weak ) .on the other hand you have the solution ( which is usually water) .water is held by strong attraction forces known as hydrogen bonding .since this type of bonding is greater than dipole dipole forces .therefore when glucose is dropped in water . water is easily able to obercome the forces that are keeping the glucose molecule intact . therefore the molecule dissolves and breaks into pieces. Hope this helps
