N2 (g) + 2O2(g) = 2NO2 (g) ΔH = 66.4 kJ 2NO (g) + O2 (g) = 2NO2 (g) ΔH = -114.2 kJ the enthalpy of the reaction of the nitrogen
RSB [31]

Answer:

ΔH  = 180.6 kJ

Explanation:

Given that:

N2 (g) + 2O2(g) = 2NO2 (g)           ΔH = 66.4 kJ

<u>2NO (g) + O2 (g) = 2NO2 (g)         ΔH = -114.2 kJ                     </u>

N2 (g) + O2 (g) = 2NO (g)              ΔH  = ????

The subtraction of both equations would yield the unknown ΔH , therefore:

ΔH = 66.4 - ( - 114.2 kJ)

ΔH  = 180.6 kJ

balance the reaction equation describing the biological formation of glucose (c6h12o6) with the lowest set of whole number coeff
Ivan

The given reaction equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.  As water is present as a reactant, it doesn’t also appear on the ’products’ side of the equation. So:

Water + carbon dioxide > glucose + oxygen.

As glucose contains 6 carbon atoms, these must be obtained from 6 molecules of CO2. So, overall:

6CO2(g) + 6H2O(l) > C6H12O6(aq) + 6O2(g).

What is photosynthesis?

Photosynthesis is the process  plants and other organisms use to convert light energy into chemical energy, which is later released through cellular respiration to power the activity of the organism.

Therefore, This is the equation for photosynthesis whereby, in the presence of light energy from the Sun and chlorophyll, plants synthesize glucose from carbon dioxide and water.
