A team of engineers has decided to design a new shoe for people suffering from a painful foot condition. Which of the following tasks should the team
undertake during the process of researching the condition?
A. Determine how much potential consumers would be willing to pay
for this new product.
B. Find a rubber manufacturer to design the sole of the new shoe.
C. Test the shoe in a trial.
D. Consult with an orthopedist about how to best accommodate
potential consumers in terms of physical comfort and pain
alleviation.

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 cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
