The space shuttle's solid rocket boosters use ammonium perchlorate and aluminum to create an explosive reaction. the unbalanced reaction can be seen below. nh4clo4(s) + al(s) yields al2o3(g) + hcl(g) + n2(g) + h2o(g) which of the following statements correctly describes this reaction? 1. chlorine is being oxidized 2. aluminum is gaining electrons 3. nitrogen is being reduced 4. aluminum is a reducing agent.

Here we have to choose the statement which correctly describe the reaction NH₄ClO₄ (s) + Al (s) → Al₂O₃ (g) + HCl (g) + N₂ (g) + H₂O (g).

The correct statement for the reaction:

NH₄ClO₄ (s) + Al (s) → Al₂O₃ (g) + HCl (g) + N₂ (g) + H₂O (g) is 4. aluminum is reducing agent.

The reaction between ammonium perchlorate and aluminium metal as given:

NH₄ClO₄ (s) + Al (s) → Al₂O₃ (g) + HCl (g) + N₂ (g) + H₂O (g)

In this reaction the change of oxidation state of each element is:

a) nitrogen (N) from -3 to 0 thus oxidation. Thus nitrogen is oxidized in this reaction.

b) chlorine (Cl) from +7 to -1 thus reduction. Thus chlorine is reduced in this reaction.

c) Aluminum (Al) from 0 to +3 state thus oxidation. Al is loosing electrons; Thus aluminum is being oxidized.

We know the gaining of electron is a reducing process and the compound itself is an oxidizing agent, whereas the loosing of electrons is a oxidation process and the compound itself is an reducing agent.

Thus aluminum is a reducing agent in this reaction.

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
