Answer:
Since the noble gases are unreactive or inert, they are safe to use. Helium is used to fill balloons and airships, because it is much lighter that air and it will not catch fire. Neon is used in advertising signs. It will give red glow, but the color can be changes by mixing it with other gases.
Explanation:
Synthesis. Iodine monobromide is formed when iodine and bromine are combined in a chemical reaction: I2 + Br2 → 2 IBr.

Exhibit 11:3 presentation outlines; Exhibit Mechanistic vs. Organic Organizations: The Building Blocks of Organizational Structure
Zappos is an organic organization. The elements in Zappos as an organization include;
• Low degree of specialization
• Flexible division of labor • Employees focus on "bigger picture" • Clear understanding of organization's core competencies and strategic intent • Domain expertise in different areas • Generalized knowledge of how to accomplish strategic goals valued • Distributed decision making • Vertical (top-down and bottom-up) as well as horizontal communication • Flat structures High span of control • Horizontal as well as two-way vertical communication • Mutual adjustment • Differentiation strategy

Answer:
1. 77.5g,
2. 1.78 mol,
3. 281 g
4. add 80 mL of water
Explanation:
1. Molar mass (Na2O) = 2*23.0 + 16.0 = 62.0 g/mol
1.25 mol *62.0 g/1mol = 77.5 g Na2O
2. Molar mass (KOH) = 39.1 +16.0+1.0 = 56.1 g/mol
100 g * 1 mol/56.1 g = 1.78 mol KOH
3. Molar mass (KOH) = 39.1 +16.0+1.0 = 56.1 g/mol
5 mol * 56.1g/1 mol = 281 g KOH
4. M1V1 =M2V2
M - molarity, V- volume of solution
2.0M*20mL = 0.4M*V2
V2 = 2.0*20/0.4 = 100 mL
Volume of diluted solution = 100 mL
We have 20 mL of solution, we need 100 mL of solution,
so we need to add (100-20) =80mL of water.
Take 20 ml 2.0 Molar of solution of HCl , add 80 mL of water, then we get 100 mL 0.4 M solution of HCl.
