Answer:
The quantity of salt is "957 lb". A further explanation is given below.
Explanation:
(1)
As we know,
1 hour 40 Min
= 60 min + 40 min
= 100 min
Salt water is going in at the rate of 2 gal/min
Salt water went into the tank in 100 min will be:
=
We have 1.92 lb of salt per gal.
In 200 gal, salt went in 1 hour 40 min will be:
=
=
Now,
ft3 = 7.5 gal
The density of solution will be:
=
=
The solution went out in 100 min 1920 lb as well as going out at 19.2 lb per min.
=
= (salt went out)
The salt remained in the tank at the end of 1 hour 40 min i.e.,
=
=
(2)
As well as the upper limit for the no. of pounds for continues stirring indefinitely per 100 gal will be:
=
Answer:- 3333 g of solution.
Some of the question part is missing here. It would be like, "Determine the mass in grams of each NaCl solution that contains 1.5 g of NaCl.
(i) 0.045% NaCl by mass
Solution:- 0.045% NaCl by mass means 0.045 g of NaCl are present in 100 g of solution. 1.5 g of NaCl would be present in how many grams of solution?
We could solve this using proportions...
(0.045/100) = (1.5/X)
0.045(X) = 1.5(100)
0.045X = 150
X = 150/0.045 = 3333
So, 1.5 g of NaCl is present in 3333 g of solution.
Answer:
Explanation:
The perfect illustration for the Table is shown below:
Generic Reactions Reactants Products Transition state
Synthesis
A + B → AB A+B = -15 kJ AB = 20 kJ 30 kJ
Single
Replacement
C + AB → CB + A C + AB = 65 kJ CB + A = 30 kJ 85 kJ
Double
Replacement
AB+CD → AD+CB AB+CD = 10 kJ AD+CB = 60 kJ 70 kJ
We are tasked to create the potential energy diagrams for each of the three chemical reactions.Then, analyze the data and your diagrams for each reaction.
TO ANSWER THAT ; I HAVE CAREFULLY DRAWN THE POTENTIAL ENERGY DIAGRAMS FOR THE THREE CHEMICAL REACTIONS & THE ANALYSIS FOR EACH ARE SHOWN IN THE DIAGRAMS ATTACHED BELOW .
NOW; over to the total change in enthalpy and the activation energy: Using the energy values provided for each reaction is : we can see the calculation of the total change in enthalpy and the activation energy in the diagram as well by using the energy values provided for each reaction.
Activation Energy Enthalpy change
Synthesis reaction 45 kJ + 35 kJ
Single replacement 20 kJ - 35 kJ
reaction
Double replacement 65 kJ + 50 kJ
