Correct name for LiCl

Answers

Answer:

lithium chloride

Explanation:

Li=Lithium

Cl=Chlorine

Final answer:

The correct name for LiCl is Lithium Chloride. It's an ionic compound composed of Lithium and Chloride ions, arranged in a lattice structure with Chloride ions contacting each other across diagonally on the face of a unit cell.

Explanation:

The correct name for LiCl is simply Lithium Chloride. This is an ionic compound, which means it is composed of two ions: the lithium ion (Li+) and the chloride ion (Cl-). In this case, Li (Lithium) loses an electron and becomes a cation (Li+), whereas Cl (Chlorine) gains that electron and becomes an anion (Cl-). The compound LiCl is then formed from the electrostatic attraction between these ions.

On the face of a LiCl unit cell, Chloride ions contact each other across the diagonal of the face, showing the close packing arrangement of the ions in the lattice structure of the compound.

It's worth noting that the common naming system for these types of compounds is quite straightforward. The name of the positive ion (the cation) comes first (Lithium), followed by the name of the negative ion (the anion) with an -ide suffix (Chloride).

Please answer number 76,77 and 78.

Answers

76. The level of muddy water will decrease slightly if the model is left in a sunny location for several days because of Evaporation. The sun will vaporize the water found in the mud, turning it into it's gaseous state, which will then cause it to rise up and get stuck on the plastic wrap.

77. Precipitation  

78.The reason that the sediment in the muddy water will remain the same is because the Mud will never evaporate like the water will, and therefore it will remain at the bottom of the container.

Write the pressure equilibrium constant expression for this reaction. 2CO2 (g) + 4H2O (g) → 2CH3OH (l) + 3O2 (g)

Answers

Answer:

The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.

Explanation:

  • For the reaction:

2CO₂ (g) + 4H₂O (g) → 2CH₃OH (l) + 3O₂ (g).

The pressure equilibrium constant (Kp) = the product of the pressure of the products side components / the product of the pressure of the reactantss side components.

each one is raised to a power equal to its coefficient.

∴ The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.
