Answer:

D

Explanation:

gas are well separated with no regular arrangement and spreaded all over. liquid are close together with no regular arrangement and slightly spreaded. solid are tightly packed, usually in a regular pattern and not spreaded at all.

On the basis of significant figures, the accuracy of measurement made using an analytical balance is more reliable.

<h3>What is an analytical balance?</h3>

An analytical balance is a special type of weighing balance that has a reputation for obtaining the mass of very small objects even as low as milligrams. It consists of a transparent glass casing and a scale.

On the basis of significant figures, the use of an analytical balance to determine the weight will improve the accuracy of the determination since it determines the mass to more significant figures.

The complex [Ni(CN)4]2- is diamagnetic and the complex [NiCl4]2- is paramagnetic. What can you conclude about their molecular ge
quester [9]

Answer:

[Ni(CN)4]2- square planar

[NiCl4]2- tetrahedral

Explanation:

For a four coordinate complex such as [Ni(CN)4]2- and [NiCl4]2-, we can decide its geometry by closely considering its magnetic properties. Both of the complexes are d8 complexes which could be found either in the tetrahedral or square planar crystal field depending on the nature of the ligand.

CN^- being a strong field ligand leads to the formation of a square planar diamagnetic d8 complex of Ni^2+. Similarly, Cl^- being a weak field ligand leads to the formation a a tetrahedral paramagnetic d8 complex of Ni^+ hence the answer given above.

Answer:

K⁺ (aq)  +  F⁻ (aq)  +  H⁺ (aq)  +  Cl⁻ (aq)  → KCl (aq) + H⁺ (aq)  +  F⁻ (aq)

Explanation:

KF (aq) +  HCl (aq) →  KCl (aq)  + HF (aq)

KF (aq) → K⁺ (aq) +  F⁻ (aq)

HCl (aq) →  H⁺ (aq)  +  Cl⁻ (aq)

KCl (aq) → K⁺ (aq) +  Cl⁻ (aq)

HF (aq) →  H⁺ (aq)  +  F⁻ (aq)
