AURORKA [14]2 years ago
4 0

Answer:

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. ... Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

How many milliliters of a 0.40%(w/v) solution of nalorphine must be injected to obtain a dose of 1.5 mg?
ozzi
The number  of Ml  of  a  0.40 %w/v solution  of   ,nalorphine  that must  be injected  to  obtain  a  dose  of 1.5 mg is  calculated as  below


since M/v%   is  mass  of solute  in  grams per 100  ml

convert Mg to  g
1 g = 1000 mg  what  about  1.5 mg =?  grams
=   1.5 /1000 = 0.0015 grams


volume is therefore =  100 (  mass/ M/v%)

= 100  x(  0.0015/ 0.4) =  0.375  ML

Listed following are some distinguishing characteristics of comets, meteors, and asteroids. Match these to the appropriate categ
9966 [12]

The distinguishing characteristics of comets, meteors, and asteroids are its composition.

<h3>What are the characteristics of comets, meteors and asteroids?</h3>

Asteroids are the fragments of rock that were left over from the creation of the solar system, Meteors are the rocks that enter the atmosphere of the Earth from space while on the other hand, Comets are the remnants of the formation of the solar system that are made of dust, rocks, and ice. All these materials i.e. comets, meteors and asteroids are different from one another due to its structure and chemical composition.

So we can conclude that the distinguishing characteristics of comets, meteors, and asteroids are its composition.

How does a network solid differ from most other covalent compounds
blondinia [14]

Answer:

Covalent compounds are held by intermolecular forces while network solids are held by strong bonds in unit cells which are closely packed together.

Explanation:

Covalent compound molecules are held by vanderwaals forces which are relatively weak but strong enough to hold some covalent molecules together in the solid state. However, network solids contain atom to atom covalent bonds arranged in an orderly manner and regular repeating unit cells to form a rigid three dimensional network solid.

Which of the following is a mixture <br><br> Water<br><br> Ink<br><br> Alcohol <br><br> Mercury
Zepler [3.9K]
Paper chromatography can be applied to "ink" to determine if it is a pure substance or a "mixture" of pure substances (in which two or more pure substances are combined). Since, tested with paper chromatography, "ink" separates into its constituent pure substances, Ink is a mixture.

I hope this helps.

P.S. Thank you for choosing me as brainliest answer on my last.
