Answer:
12.9 L Kr
General Formulas and Concepts:
<u>Chemistry - Gas Laws</u>
- Using Dimensional Analysis
- STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K
Explanation:
<u>Step 1: Define</u>
0.575 mol Kr
<u>Step 2: Identify Conversions</u>
1 mol= 22.4 L at STP
<u>Step 3: Convert</u>
<u /> = 12.88 L Kr
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
12.88 L Kr ≈ 12.9 L Kr
Answer:
The sole purpose is to rejuvenate the column. After long use the ions bound in the permutit column will get washed away. This can be replaced by washing the column with NaCl.
The property of ionic compounds is <u>Option B. they react with water and oxygen.</u>
Ionic compounds are very strong and require a lot of energy to break down so they have high boiling and melting points. Ions are formed due to electrostatic attraction between oppositely charged ions. All ionic compounds form crystals. Ionic compounds tend to have high melting and boiling points. Ionic compounds are very hard and very brittle.
Ionic compounds conduct electricity when dissolved in water. A property that is not characteristic of ionic compounds is that they are good conductors of electricity as solid crystals. Description To form a neutral ionic compound the cation and anion charges must be balanced. Some of the physical properties of ionic compounds are Physical State Ionic compounds are solid and relatively rigid due to the strong attraction between cations and anions.
