Answer:

The empirical formula of the compound would be A_2Z_3

Explanation:

The A ions are in the body center position and at each corner .

There are 8 faces of the cube and 1 corner is also shared by another 7 cubic unit.

Then number of A ion in a cubic unit = 1+\frac{1}{8}\times 8=2

The Z ions are on each face of the cubic unit :

There are 6 faces of the cube and 1 face is shared by another cubic unit.

Then number of Z ions in a cubic unit = \frac{1}{2}\times 6=3

The structural formula of the cubic lattice is  =A_2Z_3

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula of the compound would be A_2Z_3

When cyclohexene is treated with KMnO4, H2O, the syn-1,2-diol is produced. What reaction occurs when benzene is similarly treate
Ulleksa [173]

Answer:

No reaction is observed

Explanation:

The benzene ring is aromatic. Being an aromatic ring, the benzene ring is remarkably stable to all reactions that destroy the aromatic ring.

Alkenes are oxidized to alkanols in the presence of KMnO4 but this reaction does not occur with benzene. However, substituted benzenes having hydrogen atoms attached to the substituent carbon atom can be oxidized to the corresponding carboxylic acid.

A ground water tank has its height 2m. Calculate the pressure at its bottom when it is completely filled with water.​
Law Incorporation [45]

The pressure at the bottom : 19600 N/m²

<h3>Further explanation</h3>

Given

A ground water tank has its height 2m

Required

The pressure at its bottom

Solution

Hydrostatic pressure is the pressure caused by the weight of a liquid.  

The weight of a liquid is affected by the force of gravity.  

The hydrostatic pressure of a liquid can be formulated:  

\large{\boxed{\bold {P_h ~ = ~ \rho.g.h}}

Ph = hydrostatic pressure (N / m², Pa)  

ρ = density of liquid (kg / m³)  

g = acceleration due to gravity (m / s²)  

h = height / depth of liquid surface (m)  

ρ = density of water (kg / m³) = 1000

g = acceleration due to gravity = 9.8 m/ sec²

The pressure

\tt P=1000\times 9.8\times 2=19600~N/m^2

sladkih [1.3K]
 <span>Use the sequence E (NaCl, Na2SO4, then Na2S). Silver is insoluble as a chloride, so it would be removed first, the others (Pb and Ni) are soluble as chlorides(Note; lead chloride is soluble as a hot solution but will ppt when cold), next, PbSO4 is insoluble but NiSO4 is soluble so use Na2SO4 to separate lead from nickel. Lastly, nickel sulfide is insoluble and can be separated and collected.

Hope I helped :)</span>

1. An acid will have the suffix “–ic acid” at the end of its name when the negative
Nimfa-mama [501]
  • An acid will have the suffix “–ic acid” at the end of its name when the negative ion has a suffix -ide.
  • An acid will have the suffix “–ous acid” at the end of its name when the negative ion has a suffix -ite.

<h3>What is an Acid?</h3>

This is defined as a chemical substance which can react with a base to form a salt in a reaction.

The appropriate acid suffixes and conditions is however correctly given above.
