Kcal=1000 cal
Min=60 sec
0.74 *1000= 740cal/min
740 cal/min /60= 12.333 cal/s
Answer is: <span>fusion of hydrogen atoms.
For example, this nuclear reaction is in the inner core of the Sun and hydrogen is conveted into helium. </span><span>The inner core is
the central region of the Sun and all solar energy is produced in the core
by nuclear fusion.
</span>Cesium has low ionization energy
and lose one electron very easy, but for that energy is needed.
<span>Distillation of ethanol also reqiured energy and does not produce it.</span>
The elements are identified by its aomic number and they are placed in the periodic table in ascending order of atomic number.
There is one unique element for a given atomic number.
For example, atomic number 1 identifies Hydrogen and there cannot be another different element with the same atomic number.
All the elements with atomic numbers from 1 to 118 have been discovered. So, you know that there is not room for new products with atomic number equal or less than 118.
"Aristotle," thought that everything was made from "earth", "air", "fire" and "water".
Option: D
Explanation:
"Aristotle" was against to "Atomic theory" so he believed that all the things were made from earth, air, fire and water called "four classical elements". These are "four classical elements" responsible for creating all the things in "terrestrial spheres". "Aristotle" started believing that all many of the little substances were "made up" of these "four classical elements" earth, air, fire and water. But "Aristotle" views on "elements" went wrong. "Aristotle" also grasped that "heavens" are created by using "weightless" and "unchangeable" the "fifth element" called "Aether".
<span>It makes no difference which reactant is placed first, a strong acid combined stoichiometrically with a strong base will produce a neutral solution. Due to hydrolysis, a weak acid and strong base produce a basic solution when combined stoichiometrically, and a weak base and strong acid produce an acidic solution when combined stoichiometrically
Mark as brainlist please if correct! BTW have a blessed day!</span>
