Suppose that on a particular day, the atmospheric pressure supports a column of water to a height of 2.70 m. Required:
a. Calculate the corresponding atmospheric pressure in pascals.
b. Calculate the height in meters for a column of mercury required to support this same atmospheric pressure. The density of water is 1.00 g/cm' and the density of mercury is 13.6 g/cm.

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
