Using the structure of the molecule and the IUPAC nomenclature rules, predict the name of the ternary molecule HCN. A) Hydrocyan

Yakvenalex [24]

Answer:

Hydrocyanic acid.

Explanation:

Hydrocyanic acid or hydrogen cyanide is also known as formonitrile (HCN), it is a colorless, extremely poisonous liquid (because it inhibits cellular oxidative processes) which is having boiling point 26 °C, freezing point -14 °C, and highly volatile in nature.

The solution of hydrogen cyanide in aqueous is known as Prussic acid or Hydrocyanic acid. Hydrogen cyanide is used for many chemical processes such as fumigation, the concentration of ores, the case-hardening of steel and iron.

two perfumes A and B were released at the same time and you are standing 7.5metres away from both of them.molarmass of perfume A

kifflom [539]

17.40 sec is the time will take to smell second perfume after diffusion takes place

Acc. to Graham's law of Diffusion

Diffusion of Gas inversely proportional to square root of its Molecular mass.

<u>rb (Perfume B)</u>

ra(perfume A)

= $\sqrt{\frac{Ma}{Mb} }$ its equation (1)

Give molar mass of Perfume A = 275 g/mol

molar mass of Perfume B= 205g/mol putting value in (1)

» $\frac{rb}{ra}=\sqrt{\frac{275}{205} }$

$\frac{rb}{ra} =1.16$ <em> its eq (2)</em>

» Perfume B will defuse 1:16 times faster than perfume A.

Hence, perfume B will be first smelled by Person.

Sf Equal volume V of two goes diffuse in t1 and t2 sec. respectively ton

$\frac{ra}{rb}=\frac{tb}{ta}$

Now,, from eq(2) toto

1/1:15 = $\frac{tb}{ta}$

ta

Given tb =the smell of Perfume B as it diffuse faster

ta= 1.15 x 15 see

=ta2=17.40 sec

Identify the charge carried by a phosphide ion

insens350 [35]

Answer : The charge carried by a phosphide ion is, (-3)

Explanation :

In phosphide ion, the (-ide) indicates that the phosphide ion is the anion of phosphorous. So, we will have to add electrons.

As we know that the phosphorous belongs to group 5 and have 5 valence electrons.

The atomic number of phosphorous = 15

The electronic configuration of phosphorous is, $1s^22s^22p^63s^23p^3$

In phosphorous, the 'p' sub-shell is half filled. For fully filled 'p' sub-shell, we will need '3' electrons. By adding 3 electrons in 'p' sub-shell of phosphorous, (-3) charge will be created on phosphorous and named as phosphide ion.

Phosphide ion is written as, $P^{3-}$

A. List the potential acute health effects.

AleksandrR [38]

When we handle chemical substances we must be very careful because they can put our:

Physical integrity.
Health
Life at risk.

<h3>What is a chemical?</h3>

A chemical substance is a chemical compound resulting from the union of two or more chemical elements. Compounds have different uses depending on their properties. However, some can be harmful and life-threatening to humans.

<h3>Potential acute effects.</h3>

The potential acute effects of some compounds may be related to skin contact causing:

Inflammation
Redness
Rash
Burns
Dry
Among other.

On the other hand, the chronic effects of chemical compounds can be:

Diseases in the central nervous system.
Respiratory diseases.
Skin diseases.
Degenerative diseases of the bone system.

<h3>What to do when a chemical is ingested?</h3>

There are a large number of chemical substances and each one has different properties. Therefore, it is very difficult to generalize about a treatment in case of ingestion. What must be done is to know the level of risk of the substance that is being handled and avoid ingesting it at all costs. However, if it is ingested, go to the emergency room.

<h3>Product flammability</h3>

Not all chemical compounds have the same flammable response to fire. Due to the above, it is necessary to identify if the substance that we are handling is highly or slightly flammable, for this we can consult the manual of the substance or the label of its packaging.

<h3>3 Chemical that produces a potentially dangerous reaction with hydrochloric acid.</h3>

According to some studies and the hydrochloric acid safety data sheet, it can have dangerous reactions with:

Reacts violently with water.
Gives off hydrogen in reaction with metals.
Keep away from strong bases.

<h3>How to handle small spills?</h3>

Contain the spill.
Soak up with inert absorbent material.
Prevent the product from entering the sewage system.
Keep in suitable, closed containers for disposal.

<h3>Personal Protection</h3>

When we handle chemical substances we are facing a potential risk. Due to the above, protocols have been developed for its handling, which include the use of protection elements such as:

Gloves
Glasses
Helmet
Mask
Boots
Special suit.
Among others.
