Hey Secretlystupid........ANYWAYS, the percent composition of sodium phosphate is 42.1.
-Steel jelly
Answer: This is evidence that the solution a mixture.
Explanation:
Mixture :
- It is defined as a substance which is made by mixing two or more different materials.
- No chemical reaction occurs between the mixed materials.
- Usually mixture can be separated into its original components.
A solution in a dish contains 4.0 grams of salt dissolved in 100 grams of water. If 50 grams of the water evaporate is a mixture because it is made up two substances salt and water which can be easily separated out by the means of evaporation.
<u>Explanation:</u>
There are 3 states of matter:
<u>Solid state:</u> In this state of matter, the particles are closely packed and they do not have any space between them. Thus, this state of matter has the highest intermolecular forces of attraction between them.
The kinetic energy of the solid particles is the least.
<u>Liquid state:</u> In this state of matter, the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. The intermolecular forces between the particles are less as compared to the solid state.
The kinetic energy of the liquid particles lie in the intermediate of solid and gases.
<u>Gaseous state:</u> In this state, the particles are loosely arranged and have a lot of space between them. Thus, this state of matter has the lowest intermolecular forces of attraction between them.
The kinetic energy of the gaseous particles is the highest.
- <u>Conversion of solid to liquid:</u>
The spacing between the particles increases and so does the kinetic energy. The particles which were closely packed, on getting converted to liquid particles are now present in random and irregular pattern.
- <u>Conversion of liquid to gas:</u>
The spacing between the particles increases and so does the kinetic energy. The particles which were present in irregular pattern, on getting converted to gas particles are now loosely arranged.
The final temperature of the water will be 31.2 °C... i don’t know the second one sorry :(
