The answer would be "This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allowed pain to travel within the body" because this statement best explains how acupuncture reduces pain.
To support such answer, it must be noted that acupuncture is a traditional Chinese mode of pain-relieving through the insertion of extremely fine needles into the skin at specific points in the body known as "acupoints". This may relieve pain by releasing the hormone known as endorphins (happy hormone), which is the body's natural pain-killers and by affecting the brain part that governs serotonin- brain chemical which involved mood.
The bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order <u>increases</u> or <u>decreases</u> or when its potential energy is at the <u>lowest</u>.
<h3>What is bond length?</h3>
Bond length is also referred to as bond distance and it can be defined as an equilibrium distance between the nuclei of two (2) covalently bonded atoms in a molecule.
<h3>What is bond energy?</h3>
Bond energy can be defined as the amount of chemical energy that is required to break one mole of a given chemical bond.
In Chemistry, the bond length and energy of a molecule is typically determined by the following:
- The bond order or number of bonded electrons.
- The potential energy possessed by the molecule.
In conclusion, you can predict that the bond length and energy of the bond formed between hydrogen (H) and astatine (At) would change if the bond order increases or decreases or when its potential energy is at the lowest.
