What is the quantum number set of the ground-state electron that is found in helium (he) but not in hydrogen (h)
(1, 0, 0, -1/2)
(1, 0, 1, -1/2)
(1, 1, 0, -1/2)
(1, 1, 1, -1/2)

Here’s one way to follow the scientific method. place the missing steps in the correct position in the process

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

The melting point of sulfur is 115 °c and its boiling point is 445 °c. what state would sulfur be in at 200 °c?
