The answer would be: a) one substance dissolves uniformly in another substance

The solution can be made from solid, liquid or even gas as long as they are dissolves uniformly in the solvent.
It's not mandatory that a solution is made from solid mixed in liquid. If a compound made that means there is a chemical reaction happens, and that is not related to the solution.

Answer:

a.One substance dissolves uniformly in another substance.

Explanation:

Solution: It is consist of solute and solvent.

Solute is present in solution in small quantity and solvent present in large quantity in comparison to solute.

When we dissolve solute completely in the solvent then the solution is formed.

Solute and solvent can not be separated by filtration.

It is homogeneous mixture of two or more substance.

a.One substance dissolves uniformly in another substance.

It is true because when we dissolve one substance uniformly in another substance .Then substance dissolve completely and form solution.

b.liquid are mixed together

It is not true because if we mix oil and water then they will not form homogeneous mixture.

c.a compound is created.

It is not true because when a compound is formed then it is not necessary that solution is always formed.

d.Solids and liquids are mixed together

It is not true when we mix stone and water then the mixture is not homogeneous.Therefore, it is false.

• Can you explain what a scientific theory is and what a scientific law is

lions [1.4K]

A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements.A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

evablogger [386]

Answer:

Explanation:

The MSDS is Material Safety Data Sheet of HCl. Among the major hazards of hydrochloric acid is corrosive and irritant to skin and eye contact. Permanent damage may be in case.

What are the precautions to be taken while handling chemicals?

General rules for handling chemicals

Do not return chemicals to their original packaging. ...

Keep chemical containers closed. ...

Never use a wrong or an unmarked reagent. ...

Never put spatulas, stirrers or other objects into a storage container for chemicals.

What are the major hazards and what precautions would you take when handling HCl?

.Handling. Wear a chemical-resistant apron, chemical-resistant gloves and chemical splash goggles at all times when handling HCl to protect your eyes and skin. Concentrated hydrochloric acid is toxic if inhaled, so avoid breathing it in and always handle it while under a fume hood.

If heat is supplied to the stillpot too rapidly, the ability to separate two liquids by fractional distillation may be drastical

almond37 [142]

Answer:

Yes, it's temperature dependent

Explanation:

A good fractional distillation depends largely upon maintaining a temperature gradient within the column. Perfectly, the temperature at the bottom of the column should be close or similar to the boiling temperature of the solution in the pot, and it should reduce continuously in the column until it reaches the boiling point of the more volatile component at the top of the column. If the distillation flask is heated too quickly, the whole column will heat up almost distributively and eliminate the desired temperature gradient. The result will be little fractionation and separation of the components.
