Which of the following are molecules? Which of them are both molecules and compounds? oxygen (O2), carbon dioxide (CO2), sulfuric acid (H2SO4), ozone (O3), nitrogen (N2)
Hydrogen (H2), salt (NaCl), vinegar (C2H4O2), ammonia (NH3), baking soda (NaHCO3), methane (CH4)

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.

H tricky one let me think and get back to u
