B, since the percentage went up the number of foxes increased as well
108 grams of Aluminium = 4.0027369825989725 moles
Sodium hydroxide (often called just "lye") makes bar soap - solid, opaque bar soap
potassium hydroxide (often called "potash") makes liquid soap - flowing, clear or translucent liquid soap
Answer:
ΔH of reaction is -147 kJ/mol
Explanation:
For the reaction:
CH₄(g) + X₂(g) → CH₃X(g) + HX(g)
It is possible to obtain ΔHr of reaction from the sum of ΔH of products minus ΔH of reactants:
ΔHr = ΔH CH₃X + ΔH HX - (ΔH CH₄ + ΔH X₂) <em>(1)</em>
The ΔH of each compound is obtained from bond energies thus:
ΔH CH₃X = 3×C-H + C-X = 3×416 kJ/mol + 222 kJ/mol = <em>1470 kJ/mol</em>
ΔH HX = H-X = <em>277 kJ/mol</em>
ΔH CH₄ = 4×C-H = 4×416kJ/mol = <em>1664 kJ/mol</em>
ΔH X₂ = X-X = <em>230 kJ/mol</em>
Replacing in (1):
ΔHr = 1470 kJ/mol + 277kJ/mol - (1664 kJ/mol + 230 kJ/mol) = <em>-147 kJ/mol</em>

Answer : The total number of atoms in the product are, 36 atoms.
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
When 1 molecule of glucose reacts completely with 3 molecules of oxygen then it react to give 6 molecules of carbon dioxide and 6 molecules of water.
The balanced chemical reaction will be:
There are 3 atoms in carbon dioxide and 3 atoms in water.
Total number of atoms in the product = 6(3) + 6(3) = 36 atoms
Thus, the total number of atoms in the product are, 36 atoms.
