Eukaryotic celss have organelles which perform specific functions
Weather... weather is the obvious answer
<span>The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons.Hence we can say that the number of protons is 8 and the number of neutrons is 10. </span>
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
