Explanation:
It is known that,
No. of moles = Molarity × Volume
So, we will calculate the moles of as follows.
No. of moles =
= 0.0125 mol
Now, the moles of KOH are as follows.
No. of moles =
= 0.0374 mol
And, =
= 0.0375 mol
Now, the balanced reaction equation is as follows.
This means 1 mole of produces 173.2 kJ of heat. And, the amount of heat produced by 0.0125 moles of is as follows.
M =
= 2.165 kJ
Total volume of the solution = (55.0 + 55.0) ml
= 110 ml
Density of the solution = 1.13 g/ml
Mass of the solution = Volume × Density
=
= 124.3 g
Specific heat = 3.78
Now, we will calculate the final temperature as follows.
q =
2165 J =
2165 - 469.854 =
17.417 =
T =
Thus, we can conclude that final temperature of the solution is .
210 cm converted into inches is 82.67716535 in.

Explanation:
If we know the grams of a chemical compound in a specific reaction, it is possible to know the percentage of each atom that composes it.
For the Aluminum Oxide in this problem, we know its total weight and the grams of each component.
therefore we can determine the percentage ratio of its components through:
For Al

Based on what you have read about wind turbines and dams, how does a generator work? A loop of ______ spins in a ______ field, producing ______ current.
Answer:
Wire
Magnetic
Electric
Explanation:
The generator works on the principle of converting mechanical energy into electrical energy.
For example in a wind turbine generator, the mechanical energy is the wind that pushes the blades of the turbine directly that leads to conversion of this it's linear motion to the rotary motion required to make rotor of the generator to spin. Finally, the harder the wind pushes, the more the mechanical energy applied and consequently, the more electrical energy can be generated.
Now, all generators work because of the effect of the magnetic field moving past an electrical coil.
Thus, the movement of a magnet across a single loop of wire produces a voltage that is induced within the wire loop as a result of the magnetic field produced by the magnet.
As a voltage is induced across the wire loop, electrons begin to flow around the loop thereby generating electric current.
