I think O and Cl will form covalent bonds since they are both non-metals and don't have a large enough difference in electronegativities to create an ionic bond.
I hope this helps. Let me know if anything is unclear.
To determine the number of potassium laid side by side by a given distance, we simply divide the total distance to the diameter of each atom. The diameter is twice the radius of the atom. We calculate as follows:
number of atoms = 4770 / 231x10^-12 = 2.06x10^13 atoms
Answer:
When effervescent antacid tablets are dropped into water, the tablets slowly disappear and the water becomes fizzy- endothermic
On a hot day, water vapor condenses out of the air and turns into liquid droplets on the outside of a cold glass of lemonade- exothermic
The copper on the Statue of Liberty oxidizes and turns blue.- endothermic
Explanation:
An exothermic reaction is a reaction in which heat is given out to the surrounding. The temperature of the system increases when an exothermic reaction occurs. An endothermic reaction occurs when heat is absorbed and the temperature of the system decreases. Oxidation of elements and effervescence of antacid solution are endothermic processes.
Given that the water vapour in air losses energy upon condensation to liquid, the process is exothermic
The answer is green light is bent the most.
