Given :

a. BH_x b. CH_x c. NH_x d. CH_2Cl_x .

To Find :

Find the most likely vale of x for each one .

Solution :

a . BH_x

Because boron have valency of 3 .

So , x = 3 .

b . CH_x

Valency of carbon is 4 .

x = 4 .

c . NH_x

Valency of nitrogen is 3 .

Therefore , x = 3 .

d . CH_2Cl_x

Now ,we know valency of carbon is 4 and hydrogen is 1 .

Also , two hydrogen are already there .

So , only 2 electrons left to share .

Since , chlorine have valency of 1 .

Therefore , only 2 electrons of chlorine can connect .

x = 2 .

Hence , this is the required solution .

Andrew [12]

Answer:

Option C= Cobalt is not used in medicine

This statement is incorrect.

Explanation:

Pyrite is an ore of gold and is used in jewelry making (correct statement)

Pyrite:

1. pyrite is yellow brass mineral.

2. its chemical composition is  FeS2.

3. it is also called ore of gold

4. it is used in jewelry.

Talc:

Talc is used in paper making, plastics, and paint (correct statement)

1. it is phyllosilicate mineral in the form of sheets.

2. its chemical formula is Mg3Si4O10 (OH)2.

3. it is very important constituent of roofing material.

4. it is used in many industries like paper making, paints, electrical cables, food etc.

Quartz:

Quartz is used to make glass (correct statement)

1. its chemical formula is SiO2.

2. its large amount is used in manufacturing of ceramic and glass.

3. The second most abundant mineral found in the earth crust is also quartz.

Cobalt:

Cobalt is not used in medicine (incorrect statement)

1. Cobalt is widely used in medical field.

2. it is used in the detection of metastasis and tumor.

3. it is used in the replacement of knee and hip as a prosthetic alloys.

Minerals are very important in our daily life. They are widely used in construction material for example in the construction of buildings and roads and also in medical field.

Examples:

1. Copper is used in the electronic and electrical field.

2. Zinc is used in rust resistant metals, skin care creams. rubber paints etc.

Bingel [31]

A complex, ML₆²⁺, is violet. The same metal forms a complex with another ligand, Q, that creates a weaker field.  MQ₆²⁺, be expected to show green color.

<h3>What is spectrochemical series?</h3>

The ligands (attachment to a metal ion) are listed in the spectrochemical series according to the strength of their field. The series has been created by superimposing several sequences discovered through spectroscopic research because it is impossible to produce the full series by examining complexes with a single metal ion. The halides are referred to be weak-field ligands whereas the ligands cyanide and CO are strong-field ligands. Medium field effects are claimed to be produced by ligands like water and ammonia.

What is minimum volume of oxygen required to react with 42.5 g of aluminum in the synthesis of aluminum oxide at stp?
natka813 [3]
<span>26.833 liters

Aluminum oxide has a formula of Al</span>₂O₃,<span> which means for every mole of aluminum used, 1.5 moles of oxygen is required (3/2 = 1.5).

Given 42.5 g of aluminum divided by its atomic mass (26.9815385) gives 1.575 moles of aluminum.

Since it takes 1.5 moles of oxygen per mole of aluminum to make aluminum oxide, you'll need 2.363 moles of oxygen atoms.

Each molecule of oxygen gas has 2 oxygen atoms, so the moles of oxygen gas will be 2.363/2 = 1.1815

Finally, you need to calculate the volume of </span>1.1815 <span>moles of oxygen gas.
1 mole of gas at STP occupies 22.7 liters of volume. Therefore,

1.1815 * 22.7 = </span>26.8 liters <span>of oxygen gas.
