Answer: The law of conservation of mass states that mass is neither created or destroyed, so the combined mass of all the products after the reaction will be the same as the mass of all the reactants and never more, but since the flask is not closed, the gases produced from the reaction will move into the atmosphere and the product left behind , the solids and/or liquids, will be the only products that you’ll end up weighing, meaning it’ll be less weight than the original reactants. The reason I’m interchanging weight and mass is because although weight changes with gravity, so long as the gravitational force stays constant throughout the experiment, it’s pretty much the same.
Explanation:
I would say your answer is 22.4L
Hope that helps!!
have a wonderful day!!
Answer:
The density of water .
Explanation:
Density of water = 1.00 g/mL
1 lb = 453.592 g
Density of the water in :
The density of water .
Answer:
A)
Explanation:
Hi,
A) First we need to calculate the heat consumed (because the temperature decreased) by the dissolution process.
All the heat consumed was shown in the change of temperature given that there is no heat loss in the calorimeter.
So:
We know that:
The heat is:
1 mol of the amonium nitrate weighs: 80g/mol:
The heat for 1 mol:
