Solid sodium reacts with liquid water to form hydrogen gas according to the equation 2 na(s) + 2 h₂o(l) → 2 naoh(aq) + h₂(g) what is the pressure of hydrogen gas in the 20.0 l headspace of a reactor vessel when 1.00 kg sodium is reacted with excess water at 50.0°c?

my teacher would say no s

d.embryo is the correct one

the statements that apply here about binary star system are

"have stars that might appear to wobble"

"often have one star that is brighter than other"

a binary star is a star system consisting of two stars revolving around their common barycenter. systems of two or more stars are called multiple star systems.
