A scientist needs to use 4 moles of hydrogen and 2 moles of oxygen in order to make 2 moles of water. Using the molar amounts of hydrogen and oxygen, calculate the mass in grams of the samples of hydrogen and oxygen. Predict what the mass of the water (combined hydrogen and oxygen would be).

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.

Is there any options, for this
