In an alien world, a different periodic table exists. It is organized similar to the periodic table in our world, just smaller. The first group contains the alkali metals, the second group the alkaline earth metals, there are a few transition metals, and then some non-metals. The periodic table is shown below in picture form, and a table is given with molar masses and common ionic charges. Also in the table is a list of common ion groups (similar to carbonate, nitrate, etc. in our world.)

A sample contains one or more of the ions: aluminum, calcium, copper(II), iron(III); upon addition of NH3, after centrifuging, it looks like the picture shown below. For each metal put in the correct letter: P = definitely present, A = definitely absent, U = uncertain, can't tell if present or absent. aluminum = , calcium = , copper = , iron = .

1. Give reasons why the helium atom is smaller than the cesium atom. 2. A student got a problem wrong. They were asked, “How many grams of MgCl2 (molar mass = 95.21 g/mol) are needed to make 3.16 L of a 0.500 M MgCl2 solution?” The correct answer is 150. but the student got 1.58. What mistake did the student make? 3. To solve the following problem what is the reason you must subtract the vapor pressure of water, 24 torr, from the total pressure, 747 torr in order to solve the problem? “A 500.0-mL sample of H2 gas is collected over water at 298 K and 747 torr. What volume would the dry H2 gas occupy at STP? (Given: the vapor pressure of water at 298K is 24 torr).” By the way, the answer is .436 liters. NOTE: I am not asking you to solve this problem. I am asking the reason for subtracting the vapor pressure. If you simply solve the problem, you will get no points.
