Answer:
1 mol of copper
Explanation:
The mass of the oxide formed is the total mass less the crucible mass, so it is:
100.52 - 88.00 = 12.52 g
It means that 10.00 g is from copper, and 2.52 g is from oxygen. The molar mass of copper is 63.50 g/mol, and the molar mass of oxygen is 16 g/mol. The number of moles (n) is the mass divided by the molar mass:
n Cu = 10.00/63.50 = 0.158 moles
n O = 2.52/16 = 0.158 moles
So, there is the same number of moles of each element, and the product must be: CuO, which has 1 mol of copper.

it is equal to the potential energy of the products

Answer:
You should take a bite near the crust that contains very little sauce.
Explanation:
Specific heat capacity is amount of heat a one gram of substance must absorb or lose to change its temperature by one degree Celsius.
The sauce has water in it. Water has a high high heat capacity,( i.e 4.186 J/g °C, ) which means that the sauce takes more time to cool, as a result the sauce is still be hot even after few minutes of cooling, as compared to crust which has less sauce so it will cool faster.
