Answer:
V2= 531.4 ml
Explanation:
T1= 273+45 °C= 318 Kelvin
T2= 273+65 °C= 338 Kelvin
V1= 500ml *( 0.001L/1ml)= 0.5 Liters
V2= 
= 
= 0.5314465409 Liters* (1 ml/0.001 L)= 531.4 ml
Answer: There are 0.373 kJ in 373 joules.
Explanation:
According to the standard conversion units 1 kJ is equal to 1000 J. This means that 1 J is equal to 0.001 kJ.
Hence, 373 joules is converted into kilojoules as follows.
Thus, we can conclude that there are 0.373 kJ in 373 joules.
Answer:
The concentration is 4.16 grams per liter, we call the solution saturated.
Explanation:
Step 1: Data given
The solubility of calcium chromate in water is 4.16 grams per liter.
Saturated Solution : A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.
Unsaturated Solution: A solution (with less solute than the saturated solution) that completely dissolves, leaving no remaining substances.
Supersaturated Solution: A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate.
Step 2:
If the calcium chromate solution has a concentration of 4.16 grams per liter.
If the concentration is less than 4.16 grams per liter, we call it unsaturated.
If the concentration is more than 4.16 grams per liter, we call it supersaturated.
The concentration is 4.16 grams per liter, we call the solution saturated.
The answer is calcium chloride.
