Alchemists based their theories and experiments on the Aristotelian assumption that the world and everything in it are composed of four basic elements (air, earth, fire and water), along with three that were called "essential" substances: salt, mercury and sulfur.
THE FIVE BASIC ELEMENTS of the UNIVERSE: Fire, Earth, Metal, Water, Wood.
Answer:
2C2H6 + 7O2 → 4CO2 + 6H2O
Explanation:
First off you find them by balancing the equation ( equal amounts of elements on both sides) So add a two infront of the C2H6. Now you have 4 Carbons and 12 Hydrogens on the left aswell as 2 oxygens.
Now go to the right side and put a 4 infront of CO2 and a 6 infront of H2O. You now have 4 carbons 12 hydrogens and 14 oxygens on the right side.
Finally go back to the let side and place a 7 infront to make the left have 14 oxygens just like in the right. A trick to use is to save the coefficients with only one element till the end so you can do less work in the long run.
But i hope this helped its balanced and down to the smallest whole numbers possible most teachers want whole numbers as the coefficient.
These are tricky at first but once you practice a bit you will be a pro.
1. s block elements have spherical s orbital as
their outermost orbital.
2. Since s orbital can accommodate a maximum of 2 electrons, each one of these elements have 1 or two electrons.
3. These s electrons are lost very easily to form
monopositive ions by Isoing one electron in the
outermost orbital or dipositive ions by losing 2
electrons.
4. They have low ionisation potentials and low electronegativities.
5. They are good conductors of heat and electricity, excepting H2 and He.
6. They are silvery, shiny metallic substances, (with the exception of hydrogen and helium which gaseous nonmetals).
7. They are malleable and ductile, i.e., we can
make sheets and wires from them, (exception:
H2, He)
8. They readily form ionic salts with most nonmetals.
