I’m pretty sure the correct answer is “tetrad”
Answer:
The answer to your question is 0.54M
Explanation:
Data
Final concentration = ?
Concentration 1 = 0.850 M
Volume 1 = 249 ml = 0.249 l
Concentration 2 = 0.420 M
Volume 2 = 0.667 M
Process
1.- Calculate the number of moles in both solutions
Number of moles 1 = Molarity 1 x Volume 1
= 0.850 x 0.249
= 0.212
Number of moles 2 = Molarity 2 x Volume 2
= 0.420 x 0.667
= 0.280
Total number of moles = 0.212 + 0.280
= 0.492
2.-Calculate the final volume
Final volume = Volume 1 + Volume 2
Final volume = 0.249 + 0.667
= 0.916 l
3.- Calculate Molarity
Molarity = 0.492 / 0.916
Molarity = 0.54

<h3><u>Answer</u>;</h3>
<h3><u>Explanation</u>;</h3>
- Elements in the periodic table are classified into various categories including alkali metals, alkaline-earth metals, halogens, and noble gases among others.
- <u>Alkali metals are Group 1 elements in the periodic table.</u> They comprise of elements lithium (Li) through francium (Fr). They have similar characteristics and behavior.
- <u>Halogens is another category of elements which is a subset of the nonmetals.</u> They comprise group 17 of the periodic table, from fluorine (F) through Astatine (At). These elements are chemically reactive and reacts with other elements such as group 1 and group 2 element.
