Write the equilibrium constant expression for the reaction below.
kodGreya [7K]

Answer:

Kc = [H₂S]² . [CH₄] / [ H₂O]⁴ . [CS₂]

Explanation:

The equilibrium constant indicates the % of the yield reaction and can shows where the reaction is going to be equilibrated.

It works with molar concentrations on the equilibrium and it does not consider the solids compounds

Kc also can be modified by the time of the reaction.

This reaction is:

CS₂ (g) + 4 H₂O(g) ⇌ CH₄ (g) + 2H₂S (g)

Kc = [H₂S]² . [CH₄] / [ H₂O]⁴ . [CS₂]

Give example of a compound
MrMuchimi

Answer:

The seven crystal systems are a method of classifying crystals according to their atomic lattice or structure. The atomic lattice is a three dimensional network of atoms that are arranged in a symmetrical pattern. The shape of the lattice determines not only which crystal system the stone belongs to, but all of its physical properties and appearance. In some crystal healing practices the axial symmetry of a crystal is believed to directly influence its metaphysical properties. For example crystals in the Cubic System are believed to be grounding, because the cube is a symbol of the element Earth.

In your own words,provide 2 advantages of using meters as a measurement of length rather than old measurements of length such as
Dafna1 [17]

Answer:

1.Accuracy

2.Acceptance

Explanation:

1. The first advantage is Accuracy. Using meters gives us a far more precise unit of measurement because of the exact scale of reading whereas hands and steps are more of approximate methods as they may not be as accurate as the using meter due to lack of exact scale of reading.

2. The second advantage is Acceptance. Usage of meter as a unit of measurement of length is now a widely accepted unit of measurement whereas, hands and steps are not widely accepted due to their approximate nature as compared to the exact nature of metres.
