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.

A solution with a hydrogen ion concentration of 3.25 × 10-2 m is ________ and has a hydroxide concentration of _______

Romashka-Z-Leto [24]

To know the acidity of a solution, we calculate the pH value. The formula for pH is given as:

<span>pH = - log [H+] where H+ must be in Molar</span>

We are given that H+ = 3.25 × 10-2 M

Therefore the pH is:

pH = - log [3.25 × 10-2]

pH = 1.488

Since pH is way below 7, therefore the solution is acidic.

To find for the OH- concentration, we must remember that the product of H+ and OH- is equivalent to 10^-14. Therefore,

[H+]*[OH-] = 10^-14 <span>
</span>[OH-] = 10^-14 / [H+]

[OH-] = 10^-14 / 3.25 × 10-2

[OH-] = 3.08 × 10-13 M

Answers:

Acidic

[OH-] = 3.08 <span>× 10-13 M</span>

Describe what happens in a condensation reactions

dlinn [17]

A condensation reaction is described to be a reaction wherein two molecules form an even larger product and consequently produces a smaller molecule as a by-product. For example, when two amino acids are combined, a dipeptide bond is formed. As a result, 1 molecule of water is produced as a by-product.

At a certain temperature, the vapor pressure of pure benzene ‍ is atm. A solution was prepared by dissolving g of a nondissociat

erastova [34]

Answer:

Molar mass of solute: 300g/mol

Explanation:

<em>Vapor pressure of pure benzene: 0.930 atm</em>

<em>Assuming you dissolve 10.0 g of the non-volatile solute in 78.11g of benzene and vapour pressure of solution was found to be 0.900atm</em>

<em />

It is possible to answer this question based on Raoult's law that states vapor pressure of an ideal solution is equal to mole fraction of the solvent multiplied to pressure of pure solvent:

$P_{sln} = X_{solvent}P_{solvent}^0$

Moles in 78.11g of benzene are:

78.11g benzene × (1mol / 78.11g) = <em>1 mol benzene</em>

Now, mole fraction replacing in Raoult's law is:

0.900atm / 0.930atm = <em>0.9677 = moles solvent / total moles</em>.

As mole of solvent is 1:

0.9677× total moles = 1 mole benzene.

Total moles:

1.033 total moles. Moles of solute are:

1.033 moles - 1.000 moles = <em>0.0333 moles</em>.

As molar mass is the mass of a substance in 1 mole. Molar mass of the solute is:

10.0g / 0.033moles = <em>300g/mol</em>
