Electronegativity difference between Li-F
The electronegativity difference between Li (Li: 0.98) and F (F: 3.98) is 3.00.
What is an electronegativity difference?Electronegativity difference is a measure of the relative tendency of an atom in a chemical bond to attract electrons to itself. It is defined as the difference in electronegativity between two atoms in a chemical bond.
A low electronegativity difference indicates that the bond is nonpolar, with both atoms having a similar attraction to the electrons. The difference between the electronegativity of Li and F is large, indicating that the bond between them is highly polar. This means that the F atom has a greater attraction for electrons in a chemical bond than the Li atom, which results in a polar covalent bond.

2 NO + 2 CO → N₂ + 2 CO₂
By reaction stoichiometry, the following amounts of moles of each compound participate in the reaction:
NO: 2 molesCO: 2 molesN₂: 1 moleCO₂: 2 molesThe molar mass of the compounds is:
NO: 30 g/moleCO: 28 g/moleN₂: 28 g/moleCO₂: 44 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
NO: 2 moles ×30 g/mole= 60 grams
CO: 2 mole ×28 g/mole= 56 grams
N₂: 1 mole ×28 g/mole= 28 grams
CO₂: 2 moles ×44 g/mole= 88 grams
Limiting reagentThe reactant that is consumed first in a chemical reaction is called the limiting reactant, because the maximum amount of product that is formed depends on the amount of this reactant that was originally present. When this reactant is consumed, no more product can be formed and the reaction stops.
Limiting reagent in this caseTo determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 56 grams of CO reacts with 60 grams of NO, 3 grams of CO reacts with how much mass of NO?
mass of NO= (3 grams of CO× 60 grams of NO)÷ 56 grams of CO
mass of NO= 3.21 grams
But 3.21 grams of CO are not available, 3 grams are available. Since you have less mass than you need to react with 3 grams of CO, NO will be the limiting reagent.

Two factors contribute to the ocean's salt content: seabed openings and runoff from the land.
Why is the ocean salty?Most salts that dissolve in seawater come from rocks on land. Rocks crumble because of the mild acidity of rainwater that falls on land. Ions are released as a result, and these ions are transported away by streams and rivers before entering the ocean. Oceanic creatures use a large portion of the dissolved ions, which are then drawn out of the water. Others are left behind, and over time, their concentrations rise.Hydrothermal fluids, which emerge from seafloor vents, are another source of salts in the ocean. Water from the ocean seeps into seafloor fissures and is warmed by lava from the planet's core. Many chemical reactions are triggered by the heat. While picking up metals like iron, zinc, and copper from the nearby rocks, the water tends to lose oxygen, magnesium, and sulfates. Through seafloor vents, the hot water is expelled, carrying the metals with it. Volcanic eruptions that occur undersea that discharge minerals into the ocean are the source of some ocean salts.To Learn more About ocean's salt refer To:
