The first step in the metabolism of ethanol is dehydrogenation by reaction with nicotinamide-adenine dinucleotide (nad): c2h5oh+nad+→c2h4o+nadhwhat is the heat effect of this reaction upon metabolizing 10 g of ethanol from a typical cocktail? what is the total heat effect for complete metabolism of the 10 g of ethanol to co2and water? how, if at all, is the perception of warmth that accompanies ethanol consumption related to these heat effects? for computing heat effects, you may neglect the temperature, ph, and ionic strength dependence of the enthalpy of reaction

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
