The group of elements that would have an electron configuration of <span>ns^2(n-1)d^2 would be the Halogens. Elements that belong to this specific group are Fluorine, Chlorine, Bromine, and Iodine. These non-metallic elements are where simple salts are made from a reaction of hydrogen compounds.</span>
Kinetic energy maybe or something
The amount of energy in kilocalories released from 49 g of glucose given the data is -4.4 Kcal
How to determine the mole of glucose
Mass of glucose = 49 g
Molar mass of glucose = 180.2 g/mol
Mole of glucose = ?
Mole = mass / molar mass
Mole of glucose = 49 / 180.2
Mole of glucose = 0.272 mole
How to determine the energy released
C₆H₁₂O₆ →2C₂H₆O + 2CO₂ ΔH = -16 kcal/mol
From the balanced equation above,
1 mole of glucose released -16 kcal of energy
Therefore,
0.272 mole of glucose will release = 0.272 × -16 = -4.4 Kcal
Thus, -4.4 Kcal were released from the reaction
