Answer:
the mass of the copper piece is 110.2976 grams
Thus problem is providing us with the mass of iron (III) oxide as 12.4 g so the moles are required and found to be 0.0776 mol after the calculations:
<h3>Mole-mass relationships:</h3>
In chemistry, we use mole-mass relationships in order to calculate grams from moles and vice versa. In this case, since we are given the mass of iron (III) oxide as 12.4 g one can calculate the moles by firstly quantifying its molar mass:
Then, we prepare a conversion factor in order to cancel out the grams and thus, get moles:

Answer:
radiation, conduction, convection
Explanation:
A. it radiates the heat away from the pot, B. the heat is conducted, c. the heat convects to the whole pot to cook the food.
As given in statement:
[H+] = 10^-12
<span>Formula for pH:
pH = -log [H+] </span>
<span>Putting the value of H+ ion in formula:
pH = -log ( 10^-12) </span>
<span>pH = 12.0 </span>
<span>
pH 0-6 (Acidic)
pH 7 (neutral)
pH 8-14 (basic)
A solution with pH 12.0 is basic.
So according to above explanation
</span><span>a. The solution is basic in nature, is the correct answer.</span>
