The first one and last one I think
Answer: 24.0g of NaCl.
The number seems the highest, but I am not in Honors Chem (I am taking honors biology), so I do not know.
Hey there!:
Molarity of NaOH = 6 M or 6 mol/L
Volume of NaOH = 40 mL
Therefore , number of moles of NaOH:
40 mL =( 6 mol / 1000 mL)*40=
6/ 1000 * 40 => 0.24 moles of NaOH
Hope this helps!
Answer: option C) Na, Mg, K
Explanation:
Similar chemical properties are expressed by elements found in the same or close groups. There are Seven (7) groups in the Periodic table.
Of all the options, ONLY sodium Na, Magnesium Mg, and Potassium K, are located in closely together with SODIUM and MAGNESIUM being in the Same period, while SODIUM and POTASSIUM are placed in the same Group 1.
Therefore, Na, My, and K are most similar in chemical properties
