Answer:

The answer is: Law of superposition

Explanation:

In geochronology, the law of superposition is a fundamental principle given by the Danish scientist Nicolas Steno.

According to this law, in an undisturbed stratigraphic sequence,<u> the youngest strata is always found on the top of the sequence,</u> and the layers present below get progressively older as we go from the top to the bottom of the sequence. Thus, <u>the oldest strata is found at the bottom of the stratigraphic sequence.</u>

<h3>What is SDS?</h3>

SDSs provide students, researchers, workers, and emergency personnel with the proper procedures for handling a pure chemical, as well as information on what to do in an emergency situation involving the chemical.

The following items are:

A) Physical state

B) Routes of exposure and symptoms

C) Required protective equipment

D) First aid procedures

E) Fire-fighting measures

F) Chemical reactivity

G) Safe storage

H) Safe disposal

I) Environmental precautions and ecotoxicity

j) Spill cleanup procedures

A) Physical state : Thin liquid

B) Routes of exposure and symptoms :

Inhalation: Exposure to vapor or mist may irritate respiratory tract and cause coughing. Inhalation of  high concentrations may cause pulmonary edema.

Eye Contact:  Corrosive. May cause severe damage to eyes.

Skin Contact: May cause severe irritation to the skin. Prolonged contact may cause burns to the skin.

Ingestion: Ingestion may cause burns to the gastrointestinal tract and respiratory tract, nausea, vomiting,  and diarrhoea.

C) Required protective equipment :

Eye/Face Protection If splashes are likely to occur: Wear safety glasses with side shields (or goggles) or a face shield.

Skin and Body Protection Wear rubber or neoprene gloves and protective clothing such as a long-sleeved shirt.

Respiratory Protection If irritation is experienced, NIOSH/MSHA-approved respiratory protection should be worn.

Positive-pressure supplied air respirators may be required for high airborne contaminant concentrations. Respiratory protection must be provided in accordance with current local regulations.

Hygiene Measures Handle in accordance with good industrial hygiene and safety practice. Wash hands after direct contact. Do not wear product-contaminated clothing for prolonged periods. Remove  and wash contaminated clothing before re-use. Do not eat, drink, or smoke when using this  product

D) First aid procedures:

General Advice Call a poison control centre or doctor immediately for treatment advice. Show this safety data sheet to the doctor in attendance.

Eye Contact Hold eye open and rinse slowly and gently with water for 15 - 20 minutes. Remove contact lenses, if present, after the first 5 minutes, then continue rinsing the eye. Call a poison control centre or doctor for treatment advice.

Skin Contact Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Call a poison control centre or doctor for treatment advice.

Inhalation Move to fresh air. If breathing is affected, call a doctor.

Ingestion has the person sip a glassful of water if able to swallow. Do not induce vomiting unless told to do so by a poison control centre or doctor.

Do not give anything by mouth to an unconscious person. Call a poison control centre or doctor immediately for treatment advice.

Protection of First-aiders Avoid contact with skin, eyes, and clothing. Use personal protective equipment as required.

Unsuitable Extinguishing Media

CAUTION: Use of water spray when fighting fire may be inefficient.

Specific Hazards Arising from the Chemical

This product causes burns to the eyes, skin, and mucous membranes. Thermal decomposition can release sodium chlorate and irritating gases and vapours.

Explosion Data

Sensitivity to Mechanical Impact None.

Sensitivity to Static Discharge None.

Protective equipment and precautions for firefighters

As in any fire, wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or equivalent) and full protective gear.

F) Chemical reactivity

Reactivity :

Reacts with other household chemicals such as toilet bowl cleaners, rust removers, acids, or products containing ammonia to produce  hazardous irritating gases, such as chlorine and other chlorinated compounds

G) Safe storage

Store away from children. Reclose the cap tightly after each use. Store this product upright in a cool, dry area, away from direct sunlight and heat to avoid deterioration. Do not contaminate food or feed by storage of this product.  

H) Safe disposal

What is an experimental control
attashe74 [19]

The experimental control is the standard used as a comparison for the experimental groups.


For example, you may be trying to find out how different types of disinfectants affect bacterial growth.  The control group would receive <em>no</em> disinfectant whereas the experimental groups would be the ones on which the disinfectants were tested.


Hope this makes sense!
