Question

Environmental Engineering

List and describe (in one sentence each) the three dimensions of the Human Development Index (HDI).

b. Following the example and equations in the textbook, calculate each index below forJapan, Mexico, and Nigeria. The values are given in problem 1-4 at the end of chapter 1.

i. Life Expectancy Index

ii. Educational Index

iii. Income Index

iv. Human Development Index

For the HDI you calculated above

.Which is the highest? Give an explanation as to why the HDI is higher in this country.

i. Which is the lowest? Give an explanation as to why the HDI is lower in this country.

Draw simple line graphs to show the general relationship for these variables:

] Human Development Index.

ii. Expected years of schooling vs. Education Index

i. HDI vs. Life Expectancy Index

iii. Gross national income vs. Income Index

Environmental Engineering

\mathrm{NH}_{4}^{+}+2 \mathrm{O}_{2} \longrightarrow \mathrm{NO}_{3}^{-}+2 \mathrm{H}^{+}+\mathrm{H}_{2} \mathrm{O}
How many kg of oxygen is required for the complete conversion of 49 kg ofammonia (NH4-N) to nitrate (NO3 -N)? Remember that NH4-N is measured"as N", so you can assume 14 g NH4-N per mole of NH4*.
