The best answer is Titanium
Answer: Combustion reactions are characterized by the reaction of a substance with O2 to form one or more oxygen, often water. Combustion reactions emit heat, and they are important because most of society's energy is derived from them. Ex.: CH4 (g) + 2O2 (g) -- CO2 (g) + 2H2O (g)

The approximate partial pressure of oxygen at 1500 m is 0.18 atm.
<h3>Pressure of the air</h3>
From barometric pressure table;
1500 m = 85 kPa
1 kPa = 0.0099 atm
85 kPa = ?
= 0.84 atm
Oxygen percentage in air = 21%
<h3>Partial pressure of oxygen in air</h3>
P = 0.21 x P(total)
P = 0.21 x 0.84 atm
P = 0.18 atm
Thus, the approximate partial pressure of oxygen at 1500 m is 0.18 atm.

Answer:
1.08 grams of nitrogen
Explanation:
Thermally ammonium perchlorate dissociate as shown in figure.
Thus as per equation two moles of ammonium perchlorate will give four moles of water, two moles of oxygen, one mole of chlorine and one mole of nitrogen,
The molar mass of ammonium perchlorate = 117.5g/mol
Two moles of ammonium perchlorate = 2X 117.5 = 234 g
The molar mass of nitrogen = 28g
thus 234 grams of ammonium perchlorate will give 28 grams of nitrogen
Hence 9 grams of ammonium perchlorate will give 1.08 grams of nitrogen
