It is a chemical compound that lacks C-H bonds
A moon would be the correct answer.
Answer:
A . 2 O₃(g) + 2 NO ⇒ 2 O₂ (g) + 2 NO₂(g)
B . Yes
C. O and NO₃
Explanation:
A. The overall reaction is obtained by adding the individual steps in the reaction mechanism where we will get the reactants and product and the intermediates will cancel.
Thus, adding 1+ 2 +3 we get
2 O₃(g) + 2 NO ⇒ 2 O₂ (g) + 2 NO₂(g)
B. The reaction intermediates are those that are produced from the initial and/or subsequent steps and are consumed later on in the reaction mechanism, but are neither reactants nor products, they just participate.
From this definition it follows that O(g) and NO₃ are reaction intermediates.
C. O and NO₃
Answer:
A. 6 water molecules, hydrogen is limiting.
Explanation:
For a molecule of water, you need 2 hydrogen atoms and 1 oxygen atom. Therefore, if there is 6 molecules of hydrogen and 6 molecules of oxygen, there are 12 atoms of hydrogen and 12 atoms of oxygen. You need 2 of hydrogen so you will divide 12 by 2. 12-2=6. You need only 1 atom of oxygen so it will stay as 12. The limiting reactant is hydrogen because there are only 6 while there are 6 atoms of oxygen remaining. There will only be 6 water molecules formed due to the insufficient amount of hydrogen.
Answer:
By the Pauling rule, of EN
Explanation:
EN means electronegativity, the ability of atoms to attract electrons.
In the periodic table each atom, has a value of EN.
When there are two atoms bonded, you must substract the EN (the high - the low) → ΔEN
It depends on the ΔEN, that you can define a bond as ionic, covalent or metallic.
Ionic ΔEN → > 1.7
Covalent polar 0.4 < ΔEN > 1.7
Covalent non polar 0.4 < ΔEN
Two metals have always a metallic bond
