Answer:

Correct answer is Li

Explanation:

Lithium reacts with chlorine to form Lithium chloride.

$2Li+Cl_{2} \to 2LiCl$

This is a redox (Oxidation -Reduction) reaction

$2Li^{0} \to 2Li^{+2}+2e^{-}$ - Oxidation$Cl_{2}^{0}+2e^{-} \to 2Cl^{-}$  - Reduction

Hence the reducing agent in this reaction is Li

Which expression represents the concentration of OH– ions in solution? a. [OH–]  10–14 b. 10–14  [H3O+] c. 10–14  [H3O+] d. 1
7nadin3 [17]

Answer:

10^-14 / [H3O+]

Explanation:

Hydronium (H3O+) and hydroxide ions (OH-) are both present in pure water and in all aqueous solutions.

Their respective concentrations in water are 10^-7 M each and are inversely proportional to each other as given by the ion product of water, Kw.

Kw = [H3O+][OH−]

Where Kw = 1.0 * 10^-14,

[H3O+] = concentration of hydronium ions

[OH-] = concentration of hydroxide ions

Therefore, [OH-] = Kw / [H3O+]

[OH-] = 10^-14/[H3O+]

Explain why copper is used for the<br> roofs of some buildings and magnesium is not.
Scrat [10]

Answer:

Because of the less reactivity of copper.

Explanation:

As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.

Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.
