The solid oxide of generic metal M is added to 67 mL of water and reacts to produce a basic solution that is 0.40 M in the resulting compound. Neutralization of the solution required titration with 31 mL of 0.86 M HCl. How many valence electrons must M have

Answer to The solid oxide of generic metal M is added to 69 mL of water and reacts to produce a  Neutralization Of The Solution Required Titration With 31 ML Of 0.89 M HCl. How Many Valence Electrons Must M Have? to 69 mL of water and reacts to produce a basic solution that is 0.20 M in the resulting compound.

Explanation:

mark brainliess plss!

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
