Answer:
When breaking a chemical bond, energy is absorbed by the chemical bond.
Explanation:
Chemical bonds are the forces of attraction that joins two chemical species. There are two types of chemical bonds: Strong Primary and Weak Secondary bonds.
When a chemical bond is formed between two species, it is accompanied by the release of energy. Therefore, <em>bond formation is an exothermic process</em>.
<u>However, energy is always required to break a chemical bond. As energy is needed to overcome the attractive forces present between the two species.</u> Therefore, <em>bond dissociation is an endothermic process.</em>
<u><em>Therefore, during bond dissociation, energy is absorbed by the chemical bond.</em></u>
It shares the most properties with an element in its same row so it is Magnesium.
The kidneys will excrete increased quantities of acid.
Explanation:
The kidneys will excrete excess H+ ions in the blood (remember H+ ions are responsible for acidity) until the acid-base balance is restored in the blood. Bicarbonates, on the other hand, will be aggressively reabsorbed by the renal tubules as the excess H+ are being excreted.
The acid base balance is mainly determined by the quantities of H⁺ and HCO₃⁻ ions in teh blood. These ions come from the dissociation of carbonic acid formed when carbon dioxide from tissues is dissolved in blood plasma.
