Answer:
Ca2+ is an ion with a correct charge.
I do not know if this is the correct answer,
Ionic Bonds - Whichever two atoms give one electron to the other
Covalent Bond - Is whenever two atoms share electrons and they go back and forth between the two
I do not know what the third type is you would have to comment and let me know and I will try to find it for you! :)
Answer:
Potassium iodide increases the decomposition rate of hydrogen peroxide.
Explanation:
Potassium iodide increases the decomposition rate of hydrogen peroxide because potassium iodide act as a catalyst. A catalyst speed up the process of chemical reaction without reacting with the molecules present in reaction. If the potassium iodide is not present as a catalyst for the decomposition of hydrogen peroxide then the decomposition of hydrogen peroxide takes too much time because the catalyst is absent that speed up the reaction.
It would cost a little less than one thing but it was a little bit too late to get it to me
