Dan drives a pickup truck and has it loaded full of boxes. He forgets to close the tailgate before driving away and all the boxes fall out the back. Explain your reasoning

What layer of the atmosphere is directly above the troposphere?

Which formula can be used to calculate the molar mass of ammonia (nh3)? molar mass of n + molar mass of h 3 × molar mass of n + molar mass of h molar mass of n + 3 × molar mass of h 3 × molar mass of n + 3 × molar mass of h

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol
