The balance chemical reaction describing the reaction between Mg2+ and Cl- is shown below,
Mg2+ + 2Cl- ----> MgCl2
This is a reaction where there is a transfer of electrons. Since the valence electron of Mg2+ is 2 and that of Cl- is only 1. There is a need for 2 Cl- to react with 1 Mg2+ in order to balance the equation.
Thus, the anwer is MgCl2.
Direct titration of aspirin with NaOH have a side reaction simply because aspirin is a weak acid
<h3>What is direct titration?</h3>
Direct titration can simply be defined as a type of titration in which a titrant of known concentration and volume is added to a substance in order to analyze it.
As the name implies, it is called direct titration simply because the one approaches the endpoint of the experiment directly.
Furthermore, the significance of direct titration is that it is used to find the quantity of a substance within a solution with chemical reactions.
So therefore, direct titration of aspirin with NaOH have a side reaction simply because aspirin is a weak acid

Answer:
a. 226/88Ra --> 222/86Rn + 4/2He
Explanation:
Alpha decay you lose four from the mass number and two from the Atomic number. Giving you 222 mass and 86 atomic. Radon has 222 mass and 86 atomic 222/86Rn + the four from the mass we took and the two from the atomic we took. What element has 4 mass and 2 atomic. Helium 4/2He
The first person to organize the periodic table was chemist Dimitri Mendeleiv. He ordered the elements by mass number and organized them in columns and rows. These columns and rows shared similar characteristics both fisical and chemical. Back then there were only 60 or so discovered elements of the 118 that exist today. Mendeleiv left some blank spaces in between elements, predicting that future scientists would find elements to fill this spaces and these would have similar characteristics as the one around it. both of these predictions were right. However, he admitted that his method or organization may be wrong for he could have calculated the mass number incorrectly. Then another scientist named Henry Moseley found that he could reorganize the table by the atomic number and still be able to group elements by their characteristics.
I hope that answers your question!
I’m not 100% sure, but I think hydrogen gas is also produced :)
