Answer:
a. 0.4544 N
b. 
Explanation:
For computing the normality and molarity of the acid solution first we need to do the following calculations
The balanced reaction



= 0.27264 g


= 0.006816 mol
Now
Moles of
needed is

= 0.003408 mol


= 0.333984 g
Now based on the above calculation
a. Normality of acid is


= 0.4544 N
b. And, the acid solution molarity is


= 0.00005112
=
We simply applied the above formulas
Answer:
b. 10A
Explanation:
Using the formula, E= k × r×I
200= 0.5 ×2000×0.02×I
200=20×I
Dividing with 20
I = 200/20= 10A
Answer:
250.7mw
Explanation:
Volume of the reservoir = lwh
Length of reservoir = 10km
Width of reservoir = 1km
Height = 100m
Volume = 10x10³x10³x100
= 10⁹m³
Next we find the volume flow rate
= 0.1/100x10⁹x1/3600
= 277.78m³/s
To get the electrical power output developed by the turbine with 92 percent efficiency
= 0.92x1000x9.81x277.78x100
= 250.7MW
I am not sure I am stuck on this and I have been for 45 min someone please help me and this girl or boy!!
