You would add water to the mixture to dissolve the salt. When the salt is dissolved, you have your sand alone.
Explanation:
The given data is as follows.
Mass of refrigerant, m = 10 kg
Volume of the refrigerant, V = 1.595 
Formula for specific volume of the refrigerant is as follows.
v = 
= 0.1595 
So, at 
specific volume will be within 
and 
and pressure is constant.
The fluid will be in super-heated state at temperature 
and at T = pressure 1 bar = 0.1 MPa.
According to super-heated tables, the specific volume is v = 0.30138 .
Hence, the final volume will be calculated as follows.
= 
= 3.0138
Thus, we can conclude that final volume of the R-134a is 3.0138 .
Answer:
The correct option is: provide a source of counterions to prevent the build-up of charge at both the cathode to the anode.
Explanation:
A salt bridge is a U-shaped glass tube that is used in a voltaic cell or galvanic cell to connect the oxidation and reduction half-cells and complete the electric circuit.
<em>It allows the ions to pass through it, thus preventing the accumulation of charge on the anode and cathode as the chemical reaction proceeds.</em>
<u />
Therefore, the correct option is: <u>provide a source of counterions to prevent the build-up of charge at both the cathode to the anode.</u>
Answer:
A. Increasing the temperature of a chemical reaction speeds up the reaction rate.
Explanation:
The higher the temperature is, the faster a chemical reaction will happen. Food rots slower in refrigerators because it is cold, outside, they rot faster.
Combination or synthesis reaction
