Answer:
Carbon dioxide and water.
Explanation:
Oxidation which is combustion with oxygen gives off CO2 and H20 under complete combustion.
<u>Given:</u>
Enthalpy of decomposition of NO2 = 33.84 kJ/mol
<u>To determine:</u>
Enthalpy change when 2.5 moles of NO2 decomposes
<u>Explanation:</u>
The decomposition of NO2 is represented as:
2NO2(g) → N2(g) + 2O2(g)
Enthalpy change when 1 mole of NO2 decomposes is 33.84 kJ
therefore the enthalpy change corresponding to the decomposition of 2.50 moles of NO2 = 33.84 kJ * 2.40 moles/ 1 mole = 81.22 kJ
Ans: ΔH(decomposition) = 81.22 kJ

Answer: Option (3) is the correct answer.
Explanation:
In an aqueous solution, a compound exists in the form of ions that is in the form of protons and electrons.
Protons are positively charged and electrons are negatively charged. A proton (usually hydrogen ion, ) in water (solvent) also exists as .
For example,
This shows that the conjugate acid of is .
Thus, we can conclude that a hydrogen ion, H+, in aqueous solution may also be written as .
