Answer:
Losing 2 valence electrons
Gaining 2 electrons
Write a balance equation for the reaction between the analyte and the titrant.
Calculate the # of moles of titrant using the volume of titrant required and the concentration of titrant.
Calculate the # of moles of analyte using the stoichiometric coefficients of the equation.
Calculate the concentration of the analyte using the number or moles of analyte and the volume of analyte titrated.
Answer:
<h2>500 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
![k = \frac{1}{2} m {v}^{2} \\](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20m%20%7Bv%7D%5E%7B2%7D%20%5C%5C%20%20)
where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have
![k = \frac{1}{2} \times 1.6 \times {25}^{2} \\ = 0.8 \times 625 \\ = 500](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%201.6%20%5Ctimes%20%20%7B25%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%200.8%20%5Ctimes%20625%20%5C%5C%20%20%3D%20500)
We have the final answer as
<h3>500 J </h3>
