Answer:
No, tobacco companies do not reuse tobacco in their cigarettes, I also did some extra research to make sure I wasn’t giving a false answer
Thanks!
"The water becomes warmer."
<u>Remember</u>: Kinetic energy means how much, on average, a molecule is moving around. This is directly translated into heat. Therefore, the higher the kinetic energy, the more heat produced.
No it is redistributed and the state changes to gas and liquid
Limiting Reactant - The reactant in a Chemical Reaction that limits the amount of product that can be formed.
Excess Reactant - The reactant in a chemical reaction that remains when a reaction stops when the limiting reactant is completely consumed.
Theoretical Yield - The quantity of a product obtained from the complete conversion of the limiting reactant in a Chemical reaction.
I hope this helped make your question easier ^_^
Taking into account the definition of molarity, the molarity of solution of sodium sulfate is 0.0732 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Molarity of solution of sodium sulfate.</h3>
In this case, you have:
- number of moles of sodium sulfate=
(being 142 g/mole the molar mass of sodiums sulfate) - volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
Solving:
Molarity= 0.0732
Finally, the molarity of solution of sodium sulfate is 0.0732 .
