WebChemical potential energy is a form of potential energy related to the structural arrangement of atoms or molecules. This arrangement may be the result of chemical bonds within a molecule or interactions between them. Chemical energy of a chemical substance can be transformed to other forms of energy by a chemical reaction. Web20 hours ago · Contrary to the idea that apes evolved their upright posture to reach for fruit in the forest canopy, the earliest known ape with this stature, Morotopithecus, lived in more open grassy environments.

WebMar 24, 2024 · According to the above equation, you generate 852 kJ of energy for every 2 moles of Fe that are formed. So, we can calculate moles of Fe equivalent to 98.7 g, and then find the energy liberated. moles of Fe formed = 98.7 g x 1 mole/55.85 g = 1.77 moles Fe. Energy evolved = 1.77 moles Fe x -852 kJ/2 moles Fe = 754 kJ. ANSWER = 753 kJ. dog face on pajama bottoms
