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.

How are molarity and osmolarity different? What property of salts necessitates this distinction? How does this property affect t
lubasha [3.4K]

<u>Explanation:</u>

The number of moles that are present in a liter of a solution is called Molarity. Mole is the unit of Molarity.The concentration of the solutes that are present in a solution refers to Osmolarity . The unit is osmol. This helps in observing the movement of water from one side to another side of a semipermeable membrane.

The main property of salts that helps to understand the differentiation between the molarity and osmolarity is the salts Ionization.  One mole Na+ and one mole of Cl- is produced by the dissociation of a mole of sodium chloride occurs. The diffusion of water is the osmosis. Here, the one molar sodium chloride solution produces a osmotic pressure which is high than one molar glucose solution and this will not undergo dissociation.

Answer:

Carbohydrates provide energy to organisms.

Explanation:

Im 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen.
