Answer: A volume of 500 mL water is required to prepare 0.1 M 
from 100 ml of 0.5 M solution.
Explanation:
Given: 
= 0.1 M, 
= ?
= 0.5 M, 
= 100 mL
Formula used to calculate the volume of water is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that a volume of 500 mL water is required to prepare 0.1 M from 100 ml of 0.5 M solution.
Answer:
To find the mass percent of hydrogen in hydrogen chloride, we must divide the weight of the hydrogen atom alone by the weight of the entire molecule. Then we multiply by 100% to find the percentage. Thus, 2.77% of the mass of hydrogen chloride is hydrogen.

1ft=.3048meter
So if we have 2063ft and want it in meters we just do a simple unit conversion.
(2063ft)(.3048meters/1ft)=628.8meters. Here ft cancel out and leave us with meter units.
Any questions please feel free to ask. Thank you.
Energy transfer is not an efficient process.
Explanation:
There is less amount of energy in the top of the energy pyramid than at the bottom because energy transfer is not an efficient process. During the process of energy transferring, some amount is lost and some are converted to other forms of energy.
- The sun is the ultimate source of energy for all life in the solar system.
- When autotrophs takes this energy, they produce food from it.
- They use light energy from the sun to produce chemical energy in food.
- Even this conversion process waste precious amount of energy.
- As one goes up the pyramid, more energy is lost during the process of converting from one form to another.

Potassium chloride reacts with ammonium nitrate to give ammonium chloride and potassium nitrate.
This is a type of double displacement reaction. The balanced chemical equation can be represented as,
Total ionic equation for this reaction will be,
There is no apparent reaction as this reaction is not accompanied by the formation of a gas or a solid precipitate. We cannot observe any visual reaction as there is not net reaction taking place. All the ions remain as spectator ions.
