16) According to the Activity Series chemistry reference table, which of these metals will react most readily with 1.0 M HCl to produce H2(g)?
1) Zn
2) Mg
3) Ca
4) K

The correct answer is (1). Zn has the highest electronegativity of all the metals in its column. It has a strong attraction for electrons and low ionization potential, so if potassium chloride were used instead of hydrochloric acid, potassium would react most readily.

Explanation:

This question is asking which metal will react most readily. According to the activity series, alkali metals are more reactive than alkaline earth metals. Magnesium has the lowest outer electron configuration of all the metals in its row on the periodic table so it will have a strong attraction for electrons. The magnesium atom therefore requires less energy to reach an outer energy level so it has the lowest first ionization potential. Therefore, magnesium will react most readily with HCl.

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
