100 grams of KBr was dissolved in 100 grams of water at 60 degrees Celsius. The solution is .

supersaturated

saturated

unsaturated

This solutions is supersaturated

Explanation:

Step 1: Data given

Mass of KBr = 100 grams

Mass of water = 100 grams

Temperature of water = 60.0 °C

Saturated Solution =A solution with solute that dissolves until it is unable to dissolve anymore.

Unsaturated Solution= A solution (with less solute than the saturated solution) that completely dissolves.

Supersaturated Solution = A solution (with more solute than the saturated solution) that contains more undissolved solute than the saturated solution because of its tendency to crystallize and precipitate

Step 2

A KBr solution is saturated when 85.5 grams of KBr, at a temperature of 60.0 °C, is dissolved in 100 mL (100 grams ) of water.

100 grams > 85.5 grams

This solutions is supersaturated

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
