Answer:
Explanation:
The equation tells you that for every mol of H2 you need 2 mols of Na to get it.
1 H2 / 4 mols H2 = 2 mols Na / x Cross multiply
1*x = 4 * 2
x = 8 mol Na
Answer:
Resonance structures are represented in the picture below.
Explanation:
When there is a double pair of electrons shared between atoms in a molecule, the position of these electrons can be changed, without changing the molecule conformation. This occurs to stabilization, the electrons are relocated. These structures are called resonance structures.
In the molecule of NO₂F, nitrogen has 5 electrons in its valence shell, so it needs 3 electrons to be stable. Oxygen has 6 electrons and needs 2 to be stable, and fluor has 7 electrons and needs one electron to be stable.
Nitrogen still has electrons after the sharing, so it can also share one pair and will have a partial positive charge. One of the oxygens will not complete the octet, so will share only one pair f electron and will have a partial negative charge, that will compensate the positive charge in nitrogen.
The two resonance structures are shown below:
Answer: The equilibrium constant for the given reaction is 0.0421.
Explanation:
Concentration of = 0.0095 M
Concentration of = 0.020 M
Concentration of = 0.020 M
The expression of the equilibrium constant is given as:
(An equilibrium constant is an unit less constant)
The equilibrium constant for the given reaction is 0.0421.
