Answer:because they run out of energy when it is transferred and to other objects, or their kinetic energy
Explanation:
<em><u>Answer:</u></em>
Potassium.
<u><em>Explanation:</em></u>
Therefore, the answer is Potassium. You might think, that because we were talking about Argon as well, the answer is both of them, but no. Everything starts with Potassium but it decays into Argon during the process.
It will slowly rotten and turn brown
For a solution to be tested in this experiment and must be buffered to pH of 10, the [OH-] change will be, The hydroxide concentration would be higher and the formation of insoluble hydroxide salts with Mg^2 and Ca^2 would cause the determined concentration of water hardness to be too low.
<h3>What would be the [OH-] change?</h3>
Generally, the equation for the Total hardness is mathematically given as

Where

D=0.02/0.01=2
Therefore

T=1632ppm
in conclusion, The hydroxide concentration would be higher .
